【Cisco白皮书】Cisco MDS 9000 系统备份与恢复解决方案

摘　要：
Global enterprises with mission critical data residing on their servers demand continuous availability for their applications. Applications such as supply chain management (SCM), enterprise resource planning (ERP), and customer relationship management (CRM) are creating voluminous amounts of data that must be protected at all costs. At a minimum, this data must be backed up to tape regularly as an insurance policy against a potential loss of data. However, growing data volumes requiring larger storage capacity, faster servers, and also require longer time windows for backup. One must also consider that data taking several hours to backup will also take the same length of time for a full restore should the need arise. This restore time is often unacceptable as it translates into lost revenue due to extended downtime. Therefore, in many cases, tape backup is considered a minimum level of disaster recovery (DR) planning.
