dell 电脑win8改win7系统

想要让电脑预装的Windows 8 Pro操作系统变回更加熟悉的Windows 7 Professional吗?一起学习如何从Windows 8 Pro降级到Windows 7 Professional如果不备份正版win8系统,按照以下步骤就可以了。
1、开机按F2(或其它F键),进入BIOS2、在BIOS 的Boot菜单下,将Secure Boot 改为Disabled3、将Boot List Option 改为Legacy,设置启动顺序,按F10保存后,重启。
4、按F12 U盘启动进入win8pe,运行分区工具,删除分区,在“硬盘”菜单里面“转换分区表类型为mbr格式”,然后在win8下分区安装系统。
注意:win7pe会蓝屏。
详情参考:目录:1. 免责声明2. 开始之前3. 创建Windows 8恢复介质4. 将关键驱动程序下载到USB 闪存盘5. 在戴尔BIOS 中禁用安全启动6. 安装Windows 77. 从USB驱动器更新关键驱动程序 8. 从戴尔支持网站更新所有驱动程序本文档中的说明专为购买了预装Windows 8 Pro 的计算机并希望将操作系统降级为Windows 7 Professional 的客户提供。
Microsoft 不为其它Windows 8版本的客户提供降级路径,戴尔可能不会为出厂安装Windows 8 Pro 的计算机上的Windows 7 Professional 提供旧驱动程序支持。
为在此系统上实现Windows 7降级,此系统上的BIOS设置已更改为引导至传统BIOS模式。
如果未在安装前将BIOS设置更改为本机UEFI模式引导,Windows8 Pro可以安装;但是,以下Windows8 Pro功能将不起作用,因为它们依赖本机UEFI模式引导:∙安全启动∙无缝启动体验∙Bitlocker网络解锁- 用于具有可信平台模块(TPM)的系统∙eDrive支持以下系统支持从Windows 8 Pro降级到Windows 7 Professional:把计算机从Windows 8 Pro降级到Windows 7 Professional将需要以下材料:∙最多四(4)张可写DVD(DVD+R或DVD-R)或一个16GB USB闪存盘∙Windows 7 Professional安装介质(DVD或USB闪存盘)∙用于关键驱动程序的USB闪存盘(64MB或更大)开始将计算机降级到Windows 7 Professional之前,请务必为Windows 8 Pro创建恢复介质,以防将来要恢复出厂安装的操作系统。

win8 系统修复

如果出厂预装了win8,需要恢复原厂系统,可以通过调用Dell backup and Recovery进入恢复(相当于Dell Datasafe Local),调用方式:
✧如果能进入win8系统:(以下有图解)
⏹点击“开始”中的Recovery图标
⏹设置—电源--(按住shift键点击重启)--疑难解答--Dell backup and Recovery
⏹设置—更改电脑设置-常规—高级启动—立即重启--疑难解答--Dell backup and
Recovery
✧如果不能进入win8系统:
⏹多次非法关机,自动进入高级启动菜单(相当于F8的功能)--疑难解答--Dell backup
and Recovery
恢复过程中笔记本的充电器和电池必须要接着
恢复系统会把C盘的东西格式化,如果可以开机的话,要C 盘和桌面的东西,先做好备份
接下重启之后就跟第一次拿到电脑一样了。

给你的DELL本本重建Recovery分区

给你的DELL本本重建Recovery分区,恢复F8(恢复到出厂设置)功能[原创]引用地址:/thread-706761-1-1.htmlQUOTE:说明:本文仅适合安装Vista的电脑,但不限于Dell品牌电脑。
其他安装Vista的组装电脑也能轻松实现。
前言:大家知道,预装Vista的Dell本本都有一个F8修复功能(图1),供用户在Vista系统出现问题时,用户可以利用这个功能进行启动修复(图2)或恢复到DELL出厂状态(同时还有一个隐藏的Recovery分区)。
但厂方的分区常常不适合我们的需要,很多本友拿到本本后都重新分区并重新安装系统,但这样官方的这个恢复功能也同时丢失了。
本文目的就是修复这个功能(虽然DELL的这个恢复工具其实并不怎么好)。
图1好,废话少说。
我们开始,先做准备工作:一.需要工具:1. Vista安装光盘(或ISO):从中提取WinRE.wim和boot.sdi.2. ImageX:见附件。
其实这些也可以从windows aik中获得(windowsaik 下载地址:/download/9/c/1/9c123325-7ff1-41 7f-bd65-349dd97e2f1e/vista_6000.16386.061101-2205-3-LRMAIK_CN .img)3. Dell恢复工具,见附件。
这个也可以用其他工具代替,譬如Ghost。
制作过程(以下操作,除创建C盘映像在WinRE环境中操作外,其余都在Vista环境下操作):一:制作WinRE.wim和boot.sdi(从安装光盘制作)。
1. 在硬盘上(譬如D盘)建立以下2个目录D:\winre_imageD:\winre_mount2. 用Imagex命令将Windows PE映像文件复制到硬盘上将下载得到的Imagex解压到硬盘的任意地方(譬如D:\imagex),执行以下命令:D:\imagex\imagex.exe /export /boot E:\sources\boot.wim 2 D:\winre_image\winre.wim "windows Recovery Environment"(上面命令假设安装光盘在E盘)而boot.sdi直接从Vista安装光盘拷贝即可。
DELL恢复出厂设置

Dell电脑Win7重装系统后如何用Recovery分区有Factory.wim文件恢复出厂设置公司现在有一台Dell 电脑,预装的Win7 Home 32位系统,现在我们需要恢复系统,但现在安装光盘找不到了,电脑系统的Recovery分区有Factory.wim文件。
我就用Win7 Pro 64位光盘安装了系统,并从Dell公司网站下载了Backup & Recovery Manager,但是我发现“恢复系统”选项是灰色,不可选。
如何才能给恢复出厂设置呢?一、Dell Backup and Recovery Manager识别Backup.wim需要两个文件来配置,分别放在R:\DellBackups和磁盘根目录下。
①ResSys.ini文件是放在根目录下的文件,内容为:[出厂映像]ImageIndex=1Date=2010/10/1Time=00:00Location=R:\DellBackupsFilename=Backup.wimMediaType=HDDDvdNumber=0DTG=20101001000000[Backups]1=出厂映像把上述内容复制到记事本,保存为ResSys.ini②catalog.ini放在DellBackups下内容为:[Backups]20101001000000[20101001000000]20101001000000=1同样把上述内容复制到记事本保存为catalog.iniU盘下建立文件夹Dell,把两个文件放进去备用。
二、安装windows 分区:使用windows 7光盘安装盘启动安装,进入磁盘分区时按下shift+F10来启动Diskpat进行分区。
分区步骤如下:输入diskpart调动Diskpart工具,select disk 0clean (清除磁盘内容)划分隐藏的Recovery分区:create partition primary size=15360 (划分恢复分区为15G)format quick fs=ntfs label=Recovery (格式化分区并命名为Recovery)assign letter=R (分配盘符为R)set id=27 (设置为隐藏)划分windows的系统保留分区:create partition primary size=100format quick fs=ntfs label=Systemassign letter=Sactive (活动分区)划分安装操作系统的分区:create partition primary size=51200format quick fs=ntfs label=OSassign letter=C完成后连续输入两个EXIT来退出Diskpart,回到磁盘分区界面,刷新一下就看到分区了,下面安装系统。

重建DELL Recovery分区(win7)的出厂状态

重建DELL Recovery分区(win7)的出厂状态很多朋友买了DELL的电脑,由于出厂分区不适合自己需要而重装系统,造成Recovery分区消失无法恢复,本人也有过这样的经历。
如何重建分区并制作恢复出厂状态,其实只要有Dell Backup and Recovery Manager就能搞定。
下面就重建分区,制作DELL出产状态的步骤逐一作解释:一、准备工1、Windows AIK 3.02、Dell Backup and Recovery Manager(视系统版本,下载与之相匹配版本64bit或32bit)下载地址:ftp:///二、使用Windows AIK 3.0制作带ImageX的winPE3.0(略)三、制作OEM未解包状态按照符合自己需要的分区使用系统光盘或USB安装win7系统(硬盘安装没有oem信息),预留10G左右的空间以备制作Recovery。
进入系统后右键点击我的电脑-管理-本地用户和组-用户,在Administrator下右键-属性-账户已禁用前的勾去掉。
注销用户,以Administrator登陆,在控制面板里找到“用户账户”,进去原来自己建立的账户全删除,文件也删除,只要不是系统默认自带的账户都删除!在Administrator完成以下工作:1、安装驱动程序和必要的软件、并更新系统到最新状态。
为了保持系统纯洁,不要安装任何系统优化软件。
2、格式化D盘,并命名为“Recovery”,把下载的dellbackups.rar里的文件解压到D盘根目录。
3、安装并运行Dell Backup and Recovery Manager,出现“Dell备份和回复管理器”窗口后关掉它。
4、如果你使用的是DSL宽带接入并且已经建立了宽带连接,请打开网络和共享中心,右边找到“更改适配器设置”-右键“宽带连接”-删除。
回到“网络和共享中心”-双击“未识别的网络”前的那条长椅-合并或删除网络设置-宽带连接-删除。
dell_DataSafe_Local_Backup备份系统的详细解析

用dell DataSafe Local Backup基础版备份系统的详细解析测试电脑:戴尔灵越15R一、对出厂设置进行备份及还原一般刚入手一台电脑时都会对其做原始备份,也就是创建恢复介质。
步骤很简单,打开dell DataSafe Local Backup 然后选择“备份”—“创建恢复介质”—选择“光盘”或者“USB 闪存盘”。
然后根据提示即可完成创建。
本人创建的是光盘。
用此恢复介质进行系统恢复时有两种选择:1、恢复出厂设置;2、还原我的计算机方法:插入光盘后重启,按F12选择光盘启动即可进入恢复界面,选择“使用系统恢复光盘继续”—选择“选择其他系统备份和更多选项”1、恢复出厂设置:选择“出厂恢复—删除数据并重新设置所有分区”。
此项将格式化所有硬盘,删除所有数据,重新分区,重新安装系统。
包括重装恢复分区recovery、dell DataSafe Local Backup引导分区OEM、重新安装所有出厂软件。
总之电脑将恢复成出厂时的状态,恢复完成后电脑将从“首次使用win7系统”开始。
2、还原我的计算机:选择“还原我的计算机”—选择“出厂映像”。
此选项会恢复出厂时的操作系统。
对硬盘分区状态及除C盘外的其他磁盘不做改变。
二、对DIY后的系统进行备份及还原现在很多笔记本预装的都是家庭版,使用不方便,一般都会升级到旗舰版,然后安装所需软件,如果有一天系统出问题了,用dell DataSafe Local Backup基础版还原系统后又变成了家庭版,还要升级,安装自己所需的软件,很麻烦。
虽然dell DataSafe Local Backup升级到高级版可以还原到任何时间点,但是升级需要花银子。
接下来我给大家介绍一个用dell DataSafe Local Backup基础版制作属于自己的系统备份的方法。
可以用这个备份还原到自己希望的状系统态。

Backup and Recovery Strategies

2Backup and Recovery StrategiesThis chapter offers guidelines and considerations for developing an effective backup and recovery strategy.This section includes the following topics:∙Data Recovery Strategy Determines Backup Strategy∙Planning Data Recovery Strategy∙Planning Backup Strategy∙Validating Your Data Recovery StrategyData Recovery Strategy Determines Backup StrategyTo decide on backup strategies, start with your data recovery requirements and your data recovery strategy. Each type of data recovery will require that you take certain types of backup.Failures can run the gamut from user error, datafile block corruption and media failure to situations like the complete loss of a data center. How quickly you can resume normal operation of your database is a function of what kinds of restore and recovery techniques you include in your planning. Each restore and recovery technique will impose requirements on your backup strategy, including which features of the Oracle database you use to take, store and manage your backups.When thinking about recovery strategies, ask yourself questions like these:∙If a disk failed and destroyed some of the database files, such as datafiles or redo logs, how would you recover the lost files? As described in "Planning a Response to Media Failure: Restore and Media Recovery", you should be able to handle the loss of datafiles, control files, and online redo logs.∙If a logic error in an application or a user error caused the loss of important data from one or several tables or tablespaces, how could you recover that data, and what would happen to databaseupdates since the error? Could you determine the cause of the error, to prevent it from happening again? As described in "Planning aResponse to User Error: Point-in-Time Recovery and FlashbackFeatures", techniques available to you include point-in-timerecovery of the whole database or one or more tablespaces, importing data from earlier logical exports with one of the data importutilities, and using the Oracle database's flashback features.∙If the instance alert log indicates that one or more tables contains corrupt blocks, how can you repair the corruption? Does thetablespace have to remain available during the repair? As described in "Planning a Response to Datafile Block Corruption: Block Media Recovery", the RMAN BLOCKRECOVER command can help you in thissituation. Also, troubleshoot recovery with the SQL*Plus RECOVER ...TEST command.∙If the entire data center is destroyed, can you perform disaster recovery? Assume that all you have is an archive tape containing backups. How would you recover the database? How long would that recovery take?∙If you were not available to recover your database, could someone else recover it in your absence? Are your recovery proceduressufficiently automated and documented?With these needs in mind, decide how you can take advantage of features related to backup and recovery, and look at how each feature meets some requirement of your backup strategy. For example:∙Using Recovery Manager simplifies most backup and recovery operations compared to user-managed backup and recovery. Itautomates management of most backup files, including the deletion of backups and archived redo logs from disk or tape when no longer needed to meet recovery goals. It provides detailed reporting on backup activities, can verify that your available backups can be used to recover your database. Finally, RMAN makes possible many recovery techniques not available if you are using user-managedbackup and recovery, such as incremental backups.∙Flashback Database will help you restore a database to a previous time much faster than media recovery. However, you must decide in advance to keep flashback logs, and keeping flashback logs requires that you configure a flash recovery area.∙Block media recovery may be better than datafile media recovery if availability is critical. While block media recovery is possible even if you do not base your backup and recovery strategy on RMAN, RMAN-based block media recovery can be performed more quickly and with less effort.Once you decide which features to use in your recovery strategy, you can plan your backup strategy, answering the following questions, among others:∙How and where will you store your recovery-related files? Will you use a flash recovery area? Will you use an ASM disk group? Will you store backups on tape or other offline storage, or only on disk?∙At what intervals will you take scheduled backups? And what form of physical backups will you take in each situation?∙What situations require you to take a database backup outside of the regular schedule? Sometimes you must take an unscheduled backup to ensure that you can recover your data, such as after an OPENRESETLOGS or after changes to your database such as NOLOGGINGoperations that do not appear in the redo log. You may also have business requirements that require backups for auditing purposes or other reasons not related to database recovery.∙How can you validate your backups, to ensure that you can recover your database when necessary?∙How do you manage records of your backups?∙Do you have detailed recovery plans that cover each type of failure?How do your DBAs can execute these plans in a crisis? Can scripts be written to automate execution of these plans in a crisis?∙Can you apply Oracle database availability technologies, such as Data Guard or Real Application Clusters, to improve availability during a database failure? How does using these availabilitytechnologies affect your backup and recovery strategy?These are of course only a few of the considerations you should take into account. Available resources (hardware, media, staff, budget, and so on) will also be factors in your decision.Planning Data Recovery StrategyYour data recovery strategy should include responses to any number of database failure scenarios. The key to an effective, efficient strategy is envisioning failure modes, matching Oracle database recovery techniques and tools to the failure modes in which they are useful, and then making sure you incorporate the necessary backup types to support those recovery techniques.To help match failure modes to recovery techniques that can help resolve them, refer to the following sections:∙Planning a Response to User Error: Point-in-Time Recovery and Flashback Features∙Planning a Response to Media Failure: Restore and Media Recovery ∙Planning a Response to Datafile Block Corruption: Block Media RecoveryPlanning a Response to User Error: Point-in-Time Recovery and Flashback FeaturesYour backup and recovery strategy should enable you to handle situations in which a user or application makes unwanted changes to database data, such as deleting the contents of a table or making incorrect updates during a batch run. The goal in such a case will be to restore the affected parts of your database to their state before the user error.Depending on the situation, your appropriate response will be one of the following:∙If you have performed a logical backup by exporting the contents of the affected tables, sometimes you can import the data back into the table. This technique presumes that you are regularly exporting logical backups of your data, and that any changes between exports are unimportant.∙You can perform point-in-time recovery, bringing one tablespace or the whole database back to its state before the time of the error.In either case, you need backups from before the time of the error, plus the redo logs from the time of the backup to the time of the error.Note:Oracle's Flashback Technology provides faster and lessdisruptive alternatives to media recovery in manycircumstances.∙Oracle Flashback Database is a physical-levelrecovery mechanism similar to media recovery, butgenerally faster and not requiring the restore ofdata from backup.∙Oracle Flashback Table and Oracle Flashback Dropwork at the logical level, undoing unwanted changesto tables, including reversing the effects of DROPTABLE statements.∙Oracle Flashback Query and Oracle Flashback VersionQuery are useful in viewing past contents of tablesand investigating how and when logical corruptionsaffected your database.Information about these features is collected in OracleDatabase Backup and Recovery Advanced User's Guide. Thisdocument will allude to such features where they can behelpful and provide pointers for more information.Familiarize yourself with these features before planningyour backup and recovery strategy, because you may findthat they can be quite valuable and require limitedadvanced planning.Planning a Response to Media Failure: Restore and Media RecoveryA media failure occurs when a problem external to the database prevents Oracle from reading from or writing to a file during database operations. Typical media failures include physical failures, such as head crashes, and the overwriting, deletion or corruption of a database file. Media failures are less common than user or application errors, but your backup and recovery strategy should prepare for them.The type of media failure determines the recovery technique to use. For example, the strategy you use to recover from a corrupted datafile is different from the strategy for recovering from the loss of the control file.Example: Online Redo Log RecoveryThe method of recovery from loss of all members of an online log group depends on a number of factors, such as:∙The state of the database (open, crashed, closed consistently, and so on)∙Whether the lost redo log group was current∙Whether the lost redo log group was archivedFor example:∙If you lose the current group, and the database is not closed consistently (either it is open, or it has crashed), then you will have to restore an old backup and perform point-in-time recovery,followed by OPEN RESETLOGS. You will lose all transactions that were in the lost log. You should take a new full database backupimmediately after the OPEN RESETLOGS. Backups from before the OPEN RESETLOGS will not be recoverable because of the lost log.∙If you lose the current redo log group, and if the database is closed consistently, then you can perform OPEN RESETLOGS with notransaction loss. However, you should take a new full databasebackup. Backups from before the OPEN RESETLOGS will not berecoverable because of the lost log.∙If you lose a noncurrent redo log group, then you can use the ALTER DATABASE CLEAR LOGFILE statement to re-create all members in the group. No transactions are lost. If the lost redo log group was archived before it was lost, then nothing further is required.Otherwise, you should immediately take a new full backup of your database. Backups from before the log was lost will not berecoverable because of the lost log.Planning a Response to Datafile Block Corruption: Block Media RecoveryIf a small number of blocks within one or more datafiles are corrupt, you can perform block media recovery instead of restoring the datafiles from backup and performing complete media recovery of those files. The Recovery Manager BLOCKRECOVER command can be used to restore and recover specified data blocks while the database is open and the corrupted datafile is online.See Also:Oracle Database Backup and Recovery Advanced User's Guideto learn how to perform block media recovery with RMAN. Planning Backup StrategyYour plans for data recovery strategies are the basis of your plans for backup strategy. This discussion describes general guidelines that can help you decide when to perform database backups, which parts of a database you should back up, what tools Oracle provides for those backups, and how to configure your database to improve its robustness and make backup and recovery easier. Of course, the specifics of your strategy must balance the needs of your restore strategy with questions of cost, resources, personnel and other factors.Protecting Your Redundancy SetThe set of files needed to recover an Oracle database from the failure of any of its files--a datafile, control file, or online redo log--is called the redundancy set. The redundancy set should contain:∙The last backup of the control file and all the datafiles∙All archived redo logs generated after the last backup was taken ∙Duplicates of the online redo log files, generated by Oracle database multiplexing, operating system mirroring, or both ∙Duplicates of the current control file, generated by Oracle database multiplexing, operating system mirroring, or both ∙Copies of configuration files such as the server parameter file, tnsnames.ora, and listener.oraThe first rule of protecting your redundancy set is:The set of disks or other media that contain the redundancy set for your database should be separate from the disks that contain the datafiles, online redo logs, and control files.This practice ensures that the failure of a disk that contains a datafile does not also cause the loss of the backups or redo logs needed to recover the datafile. Consequently, a minimal production-level database requires at least two disk drives: one to hold the files in the redundancy set and one to hold the database files. Ideally, separate the redundancy set from the primary files in every way possible: on separate volumes, separate file systems, and separate RAID devices. Keeping the redundancy set separate from the primary files ensures that you will not lose committed transactions in a disk failure.The simplest way to manage your redundancy set is to use a flash recovery area, on a separate device from the working set files. Allrecovery-related files will be stored in a single location on disk, disk space usage is managed automatically, backups required to meet your data recovery requirements are never deleted from disk while they are still needed, and recovery time is minimized without compromising the completeness of the redundancy set.Whether or not you use a flash recovery area, Oracle Corporation recommends following these guidelines:∙Multiplex the online redo log files and current control file at the database level. (For instance, configure the database to write its online logs to two or more destinations, so that each write is a separate operation carried out by the database, rather than byoperating system-level or hardware-level redundancy.) If youmultiplex at the database level, then an I/O failure or lost write should only corrupt one of the copies.Ideally, the multiplexed files should be on different disks mounted under different disk controllers. The flash recovery area is anexcellent location for one copy of these files.You can also mirror the online redo logs and current control file at the operating system or hardware level, but this is not asubstitute for multiplexing at the database level.∙If running in ARCHIVELOG mode, archive the redo logs to multiple locations, ideally on different disks. If you are using a flashrecovery area, use it as one of the archiving locations.∙Use operating system or hardware mirroring for the control file.All copies of the control file multiplexed at the database level must be available at all times, or the instance will crash. If you use operating system or hardware mirroring for your control file, your database can continue to operate even if one copy of the control file mirrored at the operating system level is unavailable due toa disk failure.∙Use operating system or hardware mirroring for the primary datafiles if possible, to avoid having to perform media recovery for simple disk failures.∙Keep at least one copy of the entire redundancy set--including the most recent backup--on disk. The flash recovery area is the ideal location for the redundancy set.∙If the target database is stored on a RAID device, then store the redundancy set on a set of disks that are not in the same RAID device.∙If you store the redundancy set on tape, then maintain at least two copies of the data to protect against the risk of tape failure. Also, if you have more than one copy of the same data, then considerkeeping backups from different points in time. In this way, if one backup or split mirror was done when the database was corrupted, then you have an older backup when the database was not corrupted.Deciding Between ARCHIVELOG and NOARCHIVELOG ModeThe redo logs of your database provide a complete record of changes to the datafiles of your database (with a few exceptions, such as direct path loads).You can run your database in one of two modes: ARCHIVELOG mode or NOARCHIVELOG mode. In ARCHIVELOG mode, a used online redo log group must be copied to one or more archive destinations before it can be reused.Archiving the redo log preserves all transactions stored in that log, so that they can be used in recovery operations later. In NOARCHIVELOG mode, the online redo log groups are simply overwritten when the log is re-used. All information about transactions recorded in that redo log group is lost.Implications of Running in NOARCHIVELOG ModeRunning your database in NOARCHIVELOG mode imposes severe limitations on your backup and recovery strategy.∙You cannot perform online backups of your database. You must shut your database down cleanly before you can take a backup inNOARCHIVELOG mode.∙You cannot use any data recovery techniques that require the archived redo logs. These include complete and point-in-time media recovery, as described in "Forms of Data Recovery", and moreadvanced recovery techniques such as point-in-time recovery ofindividual tablespaces and Flashback Database (described in Oracle Database Backup and Recovery Advanced User's Guide.).If you are running in NOARCHIVELOG mode and you must recover from damage to datafiles due to disk failure, you have two main options for recovery:∙Drop all objects that have any extents located in the affected files, and then drop the files. The remainder of the database is intact, but all data in the affected files is lost.∙Restore the entire database from the most recent backup, and lose all changes to the database since the backup. (Recovering changes since the backup would require performing media recovery, whichuses the archived redo logs.)Implications of Running in ARCHIVELOG ModeFor most applications, running in ARCHIVELOG mode is preferable to running in NOARCHIVELOG mode because you have more flexible recovery options after a data loss. There are, however, associated costs of running in ARCHIVELOG mode:∙Space must be set aside for archiving destinations, locations on disk where the archived redo logs will be stored. These can become quite large in databases with large numbers of updates.∙The stored archived redo logs must be managed. To limit the disk space used by archived redo logs, archived redo logs can be moved to tape for longer-term storage, and older logs no longer neededto meet your recoverability goals should be deleted. (RMAN canautomate most of the management of archived redo logs, by recording the location and contents of all archived redo logs, making it easy to move archived logs to tape, and identifying and deleting redo logs no longer required to meet your recoverability objectives.) Some performance overhead is associated with the background processes ARC0 through ARC n which copy filled online redo logs to the archiving destinations.When performance requirements are extreme or disk space limitations are severe, it may be preferable to run in NOARCHIVELOG mode in spite of the restrictions imposed.Deciding Whether to Use a Flash Recovery AreaIt is recommended that you take advantage of the flash recovery area to store as many backup and recovery-related fileas as possible, including disk backups and archived redo logs.Some features of Oracle database backup and recovery, such as Oracle Flashback Database, require the use of a flash recovery area. In such cases, you must create a flash recovery area, though you do not have to use it to store all recovery-related files.Even when its use is not required, however, the flash recovery area offers a number of advantages over other on-disk backup storage methods. Backups moved to tape from the flash recovery area are retained on disk until space is needed for other required files, reducing the need to restore backups from tape. At the same time, obsolete files no longer needed to meet your recoverability goals and files backed up to tape become eligible for deletion and are deleted when space is needed, eliminating the need for DBA intervention to clear out old files.See Also:"Setting Up a Flash Recovery Area for RMAN"for more aboutthe uses and benefits of the flash recovery area.Choosing a Backup Retention PolicyYour backup retention policy is the rule you set regarding which backups must be retained (whether on disk or other backup media) to meet your recovery and other requirements.Backup retention policy can be based on redundancy or a recovery window. In a redundancy-based retention policy, you specify a number n such that you always keep at least n distinct backups of each file in your database. In a recovery window-based retention policy, you specify a time interval in the past (for example, one week, or one month) and keep all backups required to let you perform point-in-time recovery to any point during that window.A backup no longer needed to satisfy the backup retention policy is said to be obsolete.Implementing Backup Retention Policy with RMANRMAN automates the implementation of a backup retention policy, using the following commands:∙CONFIGURE RETENTION POLICY command lets you set the retention policy that will apply to all of your database files by default.∙REPORT OBSOLETE command lets you list backups currently on disk that are obsolete under the retention policy. You can also specifyparameters to see which files would be obsolete under differentretention policies.∙DELETE OBSOLETE command deletes the files which REPORT OBSOLETE would list as obsolete.∙CHANGE... KEEP lets you set a separate retention policy for specific backups, such as long-term backups kept for archival purposes. You can specify that a given backup must be kept until a future time, or even specify that a backup be kept forever. CHANGE... NOKEEP is used to let the retention policy apply to a backup previouslyprotected by CHANGE... KEEP.If you use a flash recovery area to store your backups, the database will delete obsolete backups automatically as disk space is needed for newer backups, archived logs and other files. For backups stored on disk outside a flash recovery area and for backups stored on tape, you should periodically run the DELETE OBSOLETE command to remove obsolete backups.Recovery Window-Based Backup Retention PolicyA recovery window-based retention policy lets you guarantee that you can perform point-in-time recovery to any point in the past, up to a number of days that you specify. The earliest point in time to which you can recover your database under your retention policy is known as the point of recoverability. All backups required for recovery or point-in-time recovery back to that time will be retained.Note that this will generally require that you keep backups older than the beginning of the recovery window. A point-in-time recovery to the beginning of the recovery window would require a restore from this backup, and then applying all changes between the backup time and the point of recoverability. For example, you might configure a recovery window of three days:RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;If your last full database backup was six days ago, RMAN will keep the six-day-old backup, and all redo logs required to roll the database forward to the beginning of the recovery window three days ago, in addition to any backups and redo logs needed to recover the database to all points in time within the three day window.A recovery window-based backup retention policy provides the most certain recoverability for your data. The disadvantage is that more careful disk space planning is required, since it may not be obvious how many backups of datafiles and archived logs must be retained to guarantee the recovery window.Redundancy-Based Backup Retention PolicyA redundancy-based backup retention policy determines whether a backup is obsolete based on how many backups of a file are currently on disk. You might configure a redundancy level of 3:RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 3;In this case, RMAN keeps three backups of each database file, and all redo logs required to recover all retained datafile backups to the current time. Any older backups will be considered obsolete.Assume, for instance, that you make backups of a datafile every day, starting on a Monday. On Thursday, you make your fourth backup of the datafile, and the backup from Monday becomes obsolete because you have the backups from Tuesday, Wednesday and Thursday. On Friday, the backup from Tuesday becomes obsolete, because you have the backups from Wednesday, Thursday and Friday.Archiving Older BackupsThere are several reasons to keep older backups of datafiles and archived logs:∙An older backup of datafiles and archived logs is necessary for performing point-in-time recovery to a time before your most recent backup.∙If your most recent backup is corrupt, you can still recover your database using an older backup and the complete set of archived logs since that older backup.∙You may want to keep a copy of the database for archival purposes.To perform point-in-time recovery to a given target time earlier than your current point of recoverability, then you need a database backup that completed before the target time, as well as all of the archived logs created between the time the backup was started and the target time. For example, if you take full database backups starting at 1:00 AM on February 1 (at SCN 10000) and on February 14 (at SCN 20000), and if you decide on February 28 to use point-in-time recovery to bring your database to its state at 9:00AM February 7 (SCN 13500), then you must use the February 1 backup, plus all redo logs containing changes from between the beginning of the creation of the backup (SCN 10000) and 9:00AM February 7 (SCN 13500).Note that point-in-time recovery to a time between backups is not an option for a database operating in NOARCHIVELOG mode. You can only restore your entire database from a consistent whole database backup, and re-open the database as of the time of that backup. You will lose all changes since the backup was taken.Determining Backup FrequencyFrequent backups are essential for any recovery scheme. Base the frequency of backups on the rate or frequency of database changes such as:∙Addition and deletion of tables∙Insertions and deletions of rows in existing tables∙Updates to data within tablesThe more frequently your database is updated, the more often you should perform database backups. The scenario in "Backup Scripts When Blocks Change Frequently" backs up the database every week.If database updates are relatively infrequent, then you can make whole database backups infrequently and supplement them with incremental backups (which will be relatively small because few blocks have changed).。

• Win7/Vista 系统, 可以将工厂镜像分区备份到U 盘/移动硬盘/DVD 光盘,当系统出现故障可以直接通过Usb 设备/DVD 启动恢复到出厂模式。
•您可以将Windows 系统分区(C 盘)备份为可引导的恢复 DVD ,U 盘或移动硬盘; •能将各分区的数据备份到硬盘,DVD ,USB 设备上。
如果您备份了系统也备份了各分区的文件,即使发生灾难性硬盘故障,您也可以将系统和文件完全恢复过来。
出厂镜像和数据建议不要选择备份在同一个存储设备上。
• 创建可引导的 Dell 硬件诊断程序 CD 。
出厂如果没有配置Dell 诊断光盘,借助DBRM 实现直接刻录。
警告:如果在笔记本上进行备份或恢复,Dell 强烈建议您使用 AC 电源而不是电池运行,以免中途掉电导致数据丢失。
警告:不论您是台式机或笔记本,建议禁用电源管理设置(如休眠和待机),以免导致备份和恢复进程中断。
警告:由于Dell 恢复工具下的创建系统介质只能操作一次,请拿到机器后,首先创建系统光盘。
警告:重新格式化主硬盘或删除硬盘的WRE 分区(Win7的恢复分区)将导致Dell 出厂映像丢失。
从而导致无法在恢复系统选项中使用Dell 出厂映像。
警告:要使用 Dell 备份和恢复管理器,您必须具有Windows 的管理员权限。
