How VBS works: Disaster Recovery
Leveraging VCS Global Clusters for service level DR
Veritas Ope百度文库ations Manager
• Discover vulnerabilities that lead to data loss and application outages. DR Advisor non-intrusively scans environments as often as needed • Take advantage of Symantec’s deep expertise. DR Advisor is aware of over 2,500 potential vulnerabilities – from the most common to the extremely rare • Protect all parts of the environment. DR Advisor understands DR, HA, application and SAN configurations

容灾环境面临的挑战 传统的方法成本高而且不全面！
现有方法：
• 定期进行容灾节点的配置检查
• 手工审计容灾节点配置 • 自定义脚本检查 • “Best practice” 文档
