They do not necessarily reflect EMC Corporation’s views, processes or methodologies.IntroductionThis article will focus on four things:1. New features in Avamar® 7.1 which help WAN backups2. How to estimate the bandwidth required for WAN links based on the application anddata size. This depends on the dedupe rate for the application and use of a WANemulator to measure it (Linux, open source tools, i.e. netem, etc.)3. Performance number for desktop/laptop (DTLT), Avamar Extended Retention (AER),Data Domain® (DD) with different encryption strengths4. Broad recommendations for the customerNew in Avamar 7.1 for WANStarting with Avamar 7.1, WAN is a supported configuration with Data Domain as the target storage device. With this support, metadata can be stored in Avamar and the data can be moved across the WAN to the Data Domain device.A salient feature is support of a 60-minute outage of the WAN Link and support for over-WAN backup to Data Domain as the target.Figure 1 depicts a type of network configuration that is supported.Figure 1This support provides customers the flexibility to deploy AVE’s in each remote office and have one Data Domain in a central location. Optionally, the customer can have one central Avamar server and deploy Data Domain virtual edition in each branch office.Sizing of WAN LinksThe customer has to estimate the size of the WAN links required for backing up their data. To do so, open source tools like netem, available on any Avamar server or Linux machine, can be used.Customers can use the results of the test shown below to decide where Avamar and Data Domain needs to be deployed, i.e. in a remote location or in a central office.The following set of test equipment will enable customers to easily perform the test decide for themselves.∙ESX Server - host∙Avamar Server – AVE virtual edition∙Data Domain – Virtual Edition∙Linux – SLES 11 SP1∙Windows client∙Linux ClientAvamar server virtual edition, Data Domain virtual edition, and Linux WAN emulator can be installed in a single ESX host.The network diagram will look like that which is shown in Figure 2.Figure 2Configuration∙Client should be in the same network as that of one interface of the network appliance ∙Server should be in the same network as that of one interface of the network appliance ∙Server and client should be on different network∙Data Domain should be on a different network on the same ESX hostFollow the steps below:1.ESX Configuration: Step to add new network to the ESX.o Log in to the ESX host using vSphere Cliento Click on Configurationo Click on Networkingo Click on Add networking (which will be displayed on the right side)o Select Virtual machineo Use the network label as VM Network 1o Repeat the above steps again and add VM Network 2, 3, 4, and 52.ESX VM Appliance Configuration: We need to add four interfaces to the SLES machine.The interfaces can be added by following the steps below.o Log in to the ESX host using vSphere Cliento Deploy the VM using the vmdk fileo Add disk capacityo Power Ono Right click on the VMo Edit Settingso Click on ADDo Select Ethernet Adaptero Select the VM network (for the second interface, select VM network 1 (by default first interface will be added). For the third interface, select VM Network 2)Shown below is the sample snapshot after the interfaces are added.3.ESX Configuration for client and server:o Log in in to the ESX host using vSphere Cliento Right click on the Client VMo Edit Settingso Click on the Network Adaptor and then change the label to VM Network 1o In a similar way, click on the Server VM (AVE) and then change the label to VM Network 24.IP Address on the network appliance:o Give the command ifconfig –a and get the list of interfaces (ex: eth0, eth2, eth5, etc. and then configure the IPs using the commands below (replacing theinterface respectively)i. Ifconfig eth0 10.110.209.230 netmask 255.255.252.0ii. Ifconfig eth1 192.168.2.11 netmask 255.255.255.0iii. Ifconfig eth2 192.168.1.3 netmask 255.255.255.0iv. Ifconfig eth3 192.168.3.1 netmask 255.255.255.0After configuring the IP address, the configs can be checked by using the ifconfigcommand.5.Routing-related configo Sysctl –p net.ipv4.ip_forward=1o On Client sidei. route add –net 192.168.1.0 netmask 255.255.255.0 gw 192.168.2.11ii. route add –net 192.168.3.0 netmask 255.255.255.0 gw 192.168.2.11b. On Server sidei. route add –net 192.168.2.0 netmask 255.255.255.0 gw 192.168.1.3ii. route add –net 192.168.3.0 netmask 255.255.255.0 gw 192.168.1.3c. On Data Domain sidei. route add –net 192.168.1.0 netmask 255.255.255.0 gw 192.168.3.1ii. route add –net 192.168.2.0 netmask 255.255.255.0 gw 192.168.3.1d. Route-related config can be checked using route –n commandNote: In the above sample ifconfig and route commands, the ipaddress/netmask should be replaced by your ip/netmask, respectivelyType of WAN simulations and their configurations1. Drop, delay, out-of-order(TCP Level)2. Bandwidth throttlework impairments can be done on both client/server interfacesCommands to simulate Network impairments:After executing the command, we can check whether those settings are in effect using the tc filter show dev <interface>command.How to measure the traffic on the applianceThe iptraf tool, installed and running the iptraf command, will help monitor traffic on the appliance.Follow the steps below:∙On the command line, run the command iptraf∙Enter a key to continue∙Select General Interface statistics∙Select a file to which you want to log the statsThe screen will display the traffic flowing through each of the interfaces.Below is the snapshot of how it will look after following the steps above.Performing the test set up above and using those commands, customers can simulate different WAN conditions, i.e. Drop rate, bandwidth throttle, etc.Customers can also disable WAN conditions on Avamar® and have only WAN condition for Data Domain (and vice versa), enabling them to check which application offers better results and decide on the architecture .Performance test results over WANOur testing on filesystem backup over WAN delivered the results below.Bandwidth Throttle results: With 1MbpsWith 10MbpsResults for different WAN profiles we have tested in desktop laptop environment (DTLT) are shown below.AERThe Avamar Extended Retention (AER) feature is used for Avamar backup retention to tape and restore those retained backups to clients. Formerly called Direct-to-Tape Out (DTO), it is an archiving solution for Avamar.Main tasks involved in AER are∙Exports (Identifying the backups and pushing it to tape libraries which is attached to AER Node),∙Imports (Moves the backup from Tape to AER Node (physical storage).∙Restore (Registering the client to AER and restoring the respective backups to Client).Observations∙Impact of delay on restore is greater compared to backup in exports. Additionally, there is 50% greater impact on restore compared to backup.∙Impact of bandwidth throttle is greater in restore, at least 10x worse. These things should be taken into account when the customer wants to restore (import) from AERnode.Recommendations∙WAN throughput different between medium and high encryption is minimal∙Backup window required for different clients/applications∙Test with different CPU throttles and test whether CPU usage has any impact on WAN throughput. Our assumption is that the bottleneck is only the network and thisassumption needs to be validated.Broad recommendations based on the tests conducted∙Data Domain performs better if the delay is less, in the range of 5-100ms. If the delay is 500ms, Avamar performance is much better, by at least 2x. However, with bandwidthless than 1Mbps, even with 500ms delay, Data Domain is better.∙The impact of delay when the available bandwidth is 1Mbps is much less, roughly a 20% drop in performance for Avamar and 5% for Data Domain when the delay increases from 5ms to 500ms. Hence, with bandwidth throttle, it is better to use Data Domain as storage target rather than Avamar.ConclusionPerformance numbers in WAN conditions are given in this article. The same can be used for sizing the WAN links. Customers can also easily test their numbers using open source tools like netem/tc, etc. This will help customers avoid surprises and evaluate the different products available to select the best product. This set of WAN tools cannot only be used with Avamar but also with other backup products to select the right product and right WAN size.AppendixBelow is the bandwidth script which can be used on the Linux SLES box (WAN Emulator). Using the script, bandwidth throttle can be applied and tests can be conducted.#!/bin/bash## tc uses the following units when passed as a parameter.# kbps: Kilobytes per second# mbps: Megabytes per second# kbit: Kilobits per second# mbit: Megabits per second# bps: Bytes per second# Amounts of data can be specified in:# kb or k: Kilobytes# mb or m: Megabytes# mbit: Megabits# kbit: Kilobits# To get the byte figure from bits, divide the number by 8 bit### Name of the traffic control command.TC=tc# The network interface we're planning on limiting bandwidth.IF=eth5 # Interface4# Download limit (in mega bits)DNLD=10mbit # DOWNLOAD Limit# Upload limit (in mega bits)UPLD=10mbit # UPLOAD Limitit# IP address of the machine we are controllingIP=192.168.4.12 # Host IP# Filter options for limiting the intended interface.U32="$TC filter add dev $IF protocol ip parent 1:0 prio 1 u32" start() {# We'll use Hierarchical Token Bucket (HTB) to shape bandwidth. # For detailed configuration options, please consult Linux man# page.$TC qdisc add dev $IF root handle 1: htb default 30$TC class add dev $IF parent 1: classid 1:1 htb rate $DNLD $TC class add dev $IF parent 1: classid 1:2 htb rate $UPLD$U32 match ip dst $IP/32 flowid 1:1$U32 match ip src $IP/32 flowid 1:2# The first line creates the root qdisc, and the next two lines# create two child qdisc that are to be used to shape download# and upload bandwidth.## The 4th and 5th line creates the filter to match the interface. # The 'dst' IP address is used to limit download speed, and the # 'src' IP address is used to limit upload speed.}stop() {# Stop the bandwidth shaping.$TC qdisc del dev $IF root}restart() {# Self-explanatory.stopsleep 1start}show() {# Display status of traffic control status. $TC -s qdisc ls dev $IF}case "$1" instart)echo -n "Starting bandwidth shaping: " startecho "done";;stop)echo -n "Stopping bandwidth shaping: " stopecho "done";;restart)echo -n "Restarting bandwidth shaping: " restartecho "done";;show)echo "Bandwidth shaping status for $IF:" showecho "";;*)pwd=$(pwd)echo "Usage: tc.bash {start|stop|restart|show}" ;;esacexitReferences/collaborate/workgroups/networking/netem/linux/man-pages/man8/tc-netem.8.html/index.php/tag/traffic-shaping//2.2/manual.htmlhttp://www.slashroot.in/linux-iptraf-and-iftop-monitor-and-analyse-network-traffic-and-bandwidth https:///watch?v=Y5un7JTGp3ohttps:///jterrace/1895081/man/8/ifconfig/od/commands/l/blcmdl8_route.htm/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-networking-guide.pdf/tools/traffic-control.phpEMC believes the information in this publication is accurate as of its publication date.

It integrates the latest version of Avamar software with SUSELinux as a VMware virtual machine.AVE is similar to single-node Avamar offerings on physical machines in the following ways:◆Runs autonomously as a target for all Avamar client backups◆Performs replication to a physical Avamar system or another AVEAVE is available in three configurations: 0.5 TB, 1 TB, and 2 TB licensed capacity. It is notscalable to a multi-node Avamar server and resizing the virtual machine is not supported.You can increase storage capacity by deploying additional AVEs and dividing backupsamong them. Or you can replicate your data to another Avamar server, delete the smallervirtual machine, create a larger virtual machine, and replicate your data back to the largervirtual machine.AVE supports backup of physical and virtual clients:◆For physical clients, install Avamar client software on each client◆Virtual clients can be backed up through guest OS backups (requires installing Avamarclient software on each virtual machine) or through host based backups (requires aproxy server)See the EMC Avamar Compatibility and Interoperability Matrix on the EMC online supportweb site at for a complete list of supported ESX/ESXiServer/AVE configuration scenarios.Appropriate environments for AVEThe following factors have the most direct impact on the long-term reliability, availabilityand supportability of the AVE virtual machine:◆I/O performance capability of the AVE storage subsystem◆Amount of data added daily to the AVE virtual machine (change rate)◆Capacity utilized within the AVE virtual machineSpecifications in this section and “AVE disk configuration” on page 15 describe minimumor maximum requirements for these factors. AVE generally performs better when I/Operformance is higher, and change rate and utilized capacity are lower. To maximize thecapacity that can be utilized within the AVE virtual machine, the daily change rate of thedata being protected by AVE must be balanced with adequate I/O performance.The first step in determining the proper implementation of AVE is to establish which kindof customer environment AVE will be used to protect, file server or mixed environment. Fileserver environment includes file system data and mixed environments include file systemdata and structured data (for example, database data).10EMC Avamar Virtual Edition 6.1 Installation GuideAppropriate environments for AVE 11IntroductionThe following table describes the maximum change rates supported by AVE for file server and mixed environments.Table 2 Maximum change rates supported by AVE for file server and mixed environmentsConfigurationFile server data Mixed data 0.5 TB AVE Less than 2 GB per dayFor example, this change rate corresponds to 650 GB of 100% file server data capacity or 0.3% daily change rate. See note that follows.Less than 5 GB per day For example, this change rate corresponds to 500 GB or less than 20% Microsoft Exchange or SQL Server database data and greater than 80% file server data capacity. That is 3% daily change rate for Exchange and SQL Server data, 0.3% for file server data or 1% overall. See note that follows.1 TB AVE Less than 4 GB per day For example, this change rate corresponds to 1.3 TB of 100% file server data capacity or 0.3% daily change rate. See note that follows.Less than 10 GB per dayFor example, this change rate corresponds to 1.0 TB or less than 20% Microsoft Exchange or SQL Server database data and greater than 80% file server data capacity. That is 3% daily change rate for Exchange and SQL Server data, 0.3% for file server data or 1% overall. See note that follows.2 TB AVE Less than 8 GB per dayLess than 20 GB per day rate is greater than 5 GB per day for a 0.5 TB configuration, 10 GB per day for a 1 TB configuration or 20 GB for a 2 TB configuration, deployment of a single or multi-node Avamar Data Store is required.IntroductionPre-sales performance analysisPre-sales performance analysis for AVE is required. It is performed by EMC-trainedpersonnel. Server hardware and the virtual environment must meet resource capabilitybenchmarks according to results from the AVE Performance Assurance Tool (PAT). This toolalso simulates the load imposed on the ESX/ESXi Server so that the customer can gaugethe potential impact on the targeted ESX/ESXi Server. After the PAT is complete, theinstructions contain information on how to analyze the data collected and determine if theESX/ESXi Server is a good candidate for AVE.download the PAT tool and its associated checksum file with the following FTP commands:ftp://ave_user@/PAT-3.0/PAT-3.0.zipftp://ave_user@/PAT-3.0/PAT-3.0.zip.md5sumUse the checksum file to verify the PAT file was properly downloaded.the PAT completes successfully with acceptable load levels, the Benchmark Test is notrequired. If you experience problems during installation and suspect it is bandwidthrelated, “Benchmark Testing” on page 43 is documented for troubleshooting purposes. 12EMC Avamar Virtual Edition 6.1 Installation GuideCHAPTER 2InstallationThis chapter includes the following sections:◆System requirements (14)◆Preinstallation requirements (14)◆Installation (17)◆Viewing installation history information (30)Installation13InstallationSystem requirementsAvamar Virtual Edition (AVE) is supported on VMware ESX/ESXi 4.1 and ESXi 5.0.The following table lists the minimum requirements for AVE.Table 3 Minimum requirements for AVE0.5 TB AVE 1 TB AVE 2 TB AVEProcessors dedicated to AVE Minimum two 2 GHzprocessors availableto AVE at all timesMinimum two 2 GHzprocessors availableto AVE at all timesMinimum two 2 GHzprocessors availableto AVE at all timesPhysical memorydedicated to AVE6 GB8 GB16 GBDisk space850 GB1,600 GB3,100 GBNetwork connection 1 GbE connection 1 GbE connection 1 GbE connection Preinstallation requirementsPrior to installing AVE, the following requirements must be met:◆“Preinstallation DNS configuration” on page 14◆“AVE disk configuration” on page 15◆“Additional requirements” on page 15“Best practices” on page 16 provides guidance on disk configuration. Preinstallation DNS configurationVerify that the IP address you intend to deploy the AVE to already has a reverse andforward DNS name assigned to it. Proper DNS configuration is important. Failure to haveDNS set up properly can cause many runtime or configuration issues.To confirm that DNS is configured properly:1.Open a command prompt and type:nslookup <AVE_IP_address><IP_address_of_DNS_Server>The nslookup command will return the FQDN for AVE.2.Type the following command:nslookup <AVE_FQDN> <IP_address_of_DNS_Server>The nslookup command will return the IP address for AVE.3.If the nslookup commands returned the proper information, close the commandprompt, if not resolve the DNS configuration prior to AVE installation.14EMC Avamar Virtual Edition 6.1 Installation GuidePreinstallation requirements 15InstallationAVE disk configurationPrior to AVE installation, the disks should be partitioned as follows:0.5 TB AVE is installed into four partitions:◆One operating system partition (100 GB)◆Three storage partitions (250 GB each)1 TB AVE is installed into seven partitions:◆One operating system partition (100 GB)◆Six storage partitions (250 GB each)2 TB AVE is installed into 13 partitions:◆One operating system partition (100 GB)◆12 storage partitions (250 GB each)Additional requirementsBefore installation, obtain the items listed in the following table.Table 4 Additional installation requirementsRequirementDescription ApplicationsPuTTY, WinSCP and VMware vSphere Client FilesAVE Package, operating system security patches (if applicable)Licensing dataCustomer Number (Customer ID), Reference ID (Asset Reference ID)Customer-supplied information Hostnames and IP addresses for:•AVE virtual machine•DNS server•SMTP serverGateway, netmask and domain of the AVE virtual machineFirewall openings (if appropriate)Email address for ConnectEMCfirewall requirements.InstallationBest practicesESX/ESXi supports multiple disk formats.

These andother related terms are described as follows:◆Thick provisioning — A thick disk has all space allocated when it is created. It hasoptimal I/O latencies during usage but may be a security issue as it may contain staledata as it exists on the physical media at creation.◆Thin provisioning — Space is allocated and zeroed on demand as opposed to uponcreation. There is a higher I/O penalty during the first write to an unwritten file block,but the same performance as thick and eager zeroed on subsequent writes.◆Eager zeroed — An eager zeroed thick disk has all space allocated and zeroed outwhen it is created. It has a longer creation time, but optimal performance and bettersecurity.◆Lazy zeroed — Zeroes out the block on first write, but has the same performance asthick and eager zeroed on subsequent writes.By default, in ESX 4.x, disks created on NFS storage use thin provisioning and diskscreated on block-based (SAN) storage use lazy zeroing. Both thin provisioned and lazyzeroed thick provisioned disks produce misleading benchmark testing results; EMC doesnot recommend thin/lazy zeroed provisioned disk configuration for production use of AVE.Convert a thin provision disk to thick by right-clicking the disk's.vmdk file in the datastorebrowser and choose Inflate. Convert a lazy zeroed thick provision disk to eager zeroed byusing the -k option with vmkfstools on an ESX/ESXi console command line. If a disk is thinprovisioned, it must be converted to thick before converting it to eager zero. See VMwaredocumentation for details and other methods to perform these conversions.A virtual machine running AVE aggressively uses disk I/O and is almost never idle.VMware's recommendations for appropriate resources for a high performance databaseserver virtual machine are generally applicable to an AVE virtual machine. In particular, astorage pool allocated from a group of dedicated physical disks in a RAID 1 (mirror) orRAID 10 configuration are likely to provide best performance.16EMC Avamar Virtual Edition 6.1 Installation GuideInstallationInstallationThe following topics describe how to install an AVE virtual machine.Installation roadmapThe following steps are required to install an AVE virtual machine.1.“Preparing the virtual machine” on page 172.“Running ave-part.pl” on page 203.“Configuring network settings” on page 214.“Installing AvInstaller” on page 235.“Installing and configuring Avamar software” on page 246.“Running ave-post.sh” on page 277.“Installing server software patches” on page 27Preparing the virtual machine1.Download the AVE virtual appliance and checksum file.downloaded.2.Extract the AVE virtual appliance.unch a VMware vSphere Client and connect to vCenter or directly to the ESX/ESXihost that will host the AVE virtual machine.4.Login with administrative rights.5.If you logged into vCenter, select the ESX/ESXi server that will host the AVE virtualmachine.6.Select File > Deploy OVF Template.The Source page appears.7.Select Deploy from a file and browse to the AVE virtual machine file (OVF extension).8.Click Next.The OVF Template details page appears.9.Click Next.The Name and Location page appears.Installation17Installation10.Type in the AVE name and select the inventory location.11.Click Next.The Storage page appears.12.Select the storage for AVE .13.Click Next.The Disk Format page appears.14.Select one the following.•For ESX/ESXi 4.1, select Thick Provisioned Format.•For ESXi 5.0, select Thick Provision Lazy Zero format.15.Click Next.The Network Mapping page appears.16.Map the network to the OVF template.17.Click Next.The Ready to Complete page appears.18.Confirm the deployment settings are correct.19.Click Finish.The installation may take several minutes.

EMC AVAMAR 商业版针对中端市场的专用备份应用装置要点•专为中端市场公司设计的 Avamar 商业版•全包式、价格合理的专用备份应用装置•通过网络进行传输前，在客户端消除重复数据•通过现有 LAN/WAN 链路执行快速的每日完整备份•一步恢复•全局重复数据消除将总备份存储减少到原来的 1/50•每日对服务器和数据执行可恢复性检查•提供 7.8 TB 经重复数据消除的备份磁盘存储空间•可以灵活地选择一半容量或完整容量Avamar 软件许可证选项•具备可选复制软件（非必需）的独立节点•由 EMC Velocity 渠道合作伙伴独家销售EMC Avamar 商业版是专用备份应用装置，提供可方便调整大小、全包式、价格合理且消除重复数据的备份解决方案。
该产品专为中端市场公司设计，采用简化的管理，非常适合IT 资源有限的组织。
此外，通过内置的存储恢复能力，它还消除了对第二个复制系统的需求和相关费用。
借助业内领先的 EMC Avamar 软件支持，Avamar 商业版可提供快速的每日完整备份，并且一步即可恢复物理环境和虚拟环境。
新一代备份的需求必须在可用备份窗口中保护的数据量成为影响备份性能的一个关键因素。
因为传统解决方案要反复备份所有内容，包括服务器、台式机、笔记本电脑和办公室中存在的重复文件和子文件数据段，所以效率十分低下。
在将这种传统解决方案与传统的每日增量备份和每周完整备份计划一并使用时，重复数据将多得令人震惊。
由于庞大的数据量必须通过早已拥堵不堪的网络、备份服务器和基础架构，满足备份窗口要求就成了一大挑战。
这就导致传统的备份方法总是超出可用的备份窗口，并消耗掉过多的存储。
很多中端市场公司承认重复数据消除和专用的备份应用装置是这一问题的解决之道。
但是，有限的IT资源和预算，再加上对这些新一代解决方案复杂性的主观感知，让他们的部署止步不前。
EMC Avamar 商业版解决了这些难题，并提供了一个完整、易于管理且价格合理的解决方案。

如果 Avamar 以前已备份某数据，将不再备份它。
这使备份期间通过网络传输的数据量减至最少，从而节省了大量带宽。
Avamar 可以跨客户端/ 站点消除重复数据。
这意味着，如果子文件数据块出现在受保护环境中的多个位置，Avamar 将只对它备份一次——但在恢复过程中允许任何需要该数据块的客户端进行访问。
跨客户端的全局重复数据消除大大减少了备份的存储需求。
而且，通过提供完整解决方案（包括存储、服务器、软件和支持），EMC 方便了客户，让他们只需要与一家成熟的供应商打交道即可解决其备份和恢复需要。
Avamar有多个型号——从单节点到可扩展的多节点配置，它们在功能上完全相同，只是在容量、可升级性和高可用性选项上有所差别。
Avamar支持功能包括远程访问和管理，还有系统级的“给总部发邮件”功能，其中包括可以通过 SNMP与管理框架集成的诊断功能。
再加上针对受保护客户端的 Avamar 代理，提供了一个完整、预组包并经过测试的备份和恢复解决方案。

可扩展性、高可用性和高可靠性
与许多服务器部署不同的是，Avamar 服务器利用了一种网格体系结构，只需添 加存储节点就可以让性能得到线性提高。每增加一个节点，都会增强整个网格 的 CPU、内存、I/O 和磁盘容量。增加存储节点时，数据会自动保持负载平衡， 同时不会对系统性能造成影响。
对于远程办公室，可在服务器上部署高效的轻量级 Avamar 软件代理，而无需添 置远程硬件。这样就可通过现有的广域网连接将数据直接备份到数据中心的中 央 Avamar Data Store，而无需使用本地磁带备份，避免了将磁带送往异地的相关 风险。
在执行特定于应用程序的备份时，Avamar 可使用 EMC Data Domain Boost 软件将企 业应用程序数据（Oracle、SQL、Sharepoint、Exchange、VMware 映像）直接发送 至 Data Domain 系统。现在，客户可以利用业界领先的重复数据消除软件和硬件 来统一数据保护过程，进而打造出性能最高、可扩展性最强的备份和恢复解决 方案。
EMC AVAMAR
重复数据消除备份软件和系统
重要功能
• 通过网络进行传输前，在客户端消 除重复数据
• 非常适合于保护 VMware 环境、远程 办公室、NAS 服务器及台式机/笔记 本电脑
• 备份窗口最多可缩短 %；一步恢复 • 备份所需的网络带宽最多可减少 % • 通过现有 LAN/WAN 链路安全地备份
灵活的部署选项满足您的实际需要
Avamar 提供了多种解决方案部署选项，您可以根据具体使用情形和恢复要求灵 活选择。EMC Avamar Data Store 是一款采用 RAIN 网格技术的全包式备份和恢复解 决方案，它将 Avamar 软件与经 EMC 认证的硬件集成在一起，可简化部署过程。 复制的 Avamar Data Store 单节点非常适合于具有严格 SLA 的小型公司或远程办 公室。
高效的重复数据消除
确定数据段大小的方法是在子文件级别消除冗余数据的关键因素之一。市场上 的有些解决方案在执行重复数据消除时使用固定长度数据段。采用这种方法， 即便对数据集只进行很小的改动（例如，在文件开头插入数据）也会改变数据 集中所有后续的固定长度数据段。虽然实际上只更改了很少的数据，但是整个 文件将显示为必须重新备份的新数据。
高效导出到磁带
如果您需要使用磁带介质，Avamar Data Transport 可将经过 Avamar 重复数据消除处 理的备份数据轻松导出到物理磁带，以实现经济高效的长期存储。利用 Avamar 强大的重复数据消除技术，可通过 EMC NetWorker® 和其他流行备份软件在磁带上 高效存储日常完整备份。Avamar 可通过验证数据的完整性让您高枕无忧，并提 供可搜索的目录来简化磁带恢复。此外，直观的界面和精简的报告，可使整个 过程易于管理。
在远程办公室，由于网络带宽有限，几乎没有可能集中自动执行基于广域网的 备份。因此，备份任务必须由非 IT 员工处理。容易发生故障的磁带型硬件以及 临时的手动操作过程难以为远程办公室数据提供可靠的保护。
保护 NAS 文件服务器也成为一项异常艰难的任务，尤其是在分配的时间段内无 法完成完整备份时，这既影响员工生产效率，又会使数据处于无保护状态。
和复制数据
• 全局重复数据消除最多可使总体备 份存储需求减少 %
• 独立节点冗余阵列 (RAIN) 可提供高 可用性和高可靠性
• 每日对服务器和数据执行可恢复性 检查
• 将消除了重复数据的备份数据导出 到磁带，以实现长期存储
• 灵活的部署选项：仅 Avamar 软件、 Avamar Data Store、Avamar Virtual Edition for VMware
传统解决方案需要额外的存储容量来备份重复的数据，这同样增加了成本。为 了遵从法规，需要满足其数据保留要求，这常会使问题进一步加剧。另外，传 统备份通常涉及到将物理磁带运送到异地，这样可能会导致机密信息暴露、失 窃或数据丢失。
产品介绍
EMC Avamar Data Store
从不重复备份同一数据
EMC Avamar 可先减少客户端的备份数据量，再通过网络传输和存储数据，实现 了快速、高效的备份和恢复。Avamar 可提供快速的每日完整备份，所需时间只 是传统备份的几分之一。Avamar 还可跨服务器、台式机、笔记本电脑和世界各 地的办公室全局消除重复的备份数据，最多可使总体磁盘存储需求减少 %。 结果，Avamar 不仅可以帮助您在磁盘上高效而长期地保留备份数据，同时极大 地降低了资本开支和运营开支（包括占地面积、耗电量和制冷）。
传统数据保护方式的缺点
影响备份性能的一个关键因素是必须在可用备份窗口中保护的数据量。因为传 统解决方案要反复备份所有内容，包括服务器、台式机、笔记本电脑和办公室 中存在的重复文件和子文件数据段，所以效率十分低下。在将这种传统解决方 案与传统的每日增量备份和每周完整备份计划一并使用时，重复数据将多得令 人震惊。由于巨大的数据量必须通过早已拥塞不堪的网络、备份服务器和基础 架构，在备份窗口内完成备份往往成为一项异常艰难的任务。
• 与 Data Domain 系统集成，可实现特 定于应用程序的备份
如今，数据呈指数级增长，法规遵从性要求和服务级别协议日益严格，备份窗 口不断缩小，这一切让企业不得不重新审视自己的数据保护方法。由于企业不 断寻求极富进取的虚拟化战略，并且需要更好地保护驻留在远程办公室的数 据，IT 团队面临着更多新的难题。
“磁带根本无法满足我们的需要。Avamar 解决 方案为我们提供了更得力的数据保护，让我 们在需要时可以更有效地恢复丢失的数据。 这样，我们就可以更快地恢复发生故障的 系统，并缩短恢复面向客户的服务所需的 时间。”
TODD GOURD IT 系统管理经理 CHEROKEE NATION ENTERPRISES
