ABSTRACT
For the average business, a backup and recovery system represents the most pervasive data protection option that will be deployed. Replication, snapshots, and continuous availability are typically focused on mission critical or business-essential systems (or compliance regulated systems), while backup and recovery systems might interact with as much as 100% of the systems in an environment—far more systems than end users might be aware of. In such a model, the data protection storage becomes a centralization locus. The backup and recovery system should still be a largely centralized environment (with even the application and database servers performing filesystem and OS layer backups to the system), which allows for continued efficient management of much of the data protection strategy for the environment. To perform a complete system recovery from such a backup configuration, the full backup, the most recent differential backup, and any incremental backups performed since that differential would be required for recovery.
