SnapManager protects your data by creating backups of your databases (Snapshot copies). You can increase your data protection by using built-in mirroring and archiving technologies (SnapMirror and SnapVault) or by archiving backups to third-party tape devices. You need to prepare your environment if you want to use SnapMirror or SnapVault with SnapManager.
You can use any combination of the following methods to protect your data on secondary storage.
Method | Description |
---|---|
Replicating volumes using SnapMirror | SnapMirror technology mirrors a Snapshot copy of data on a source volume to one or more destination volumes. After source and destination relationships are established, a SnapMirror baseline transfer initializes the mirror to create a replica of the source on the destination. |
Archiving backups using SnapVault | SnapVault is a disk-to-disk backup and recovery solution. It leverages the efficiencies of Snapshot copies and protects data at the block level. After the initial full backup is complete, only changed blocks are replicated to the secondary storage system. |
Archiving backups to third-party tape devices | You can use NDMP, the storage system's dump command, or a Windows backup utility to archive backups to tape. |
The following table describes the advantages and disadvantages of each method.
