Performing BLI Backups

The BLI Backup method uses snapshots to perform Full, Incremental, and Differential Backups of the selected volumes. You can either create a snapshot with Plug‑in for SnapMirror to Tape or use an existing snapshot to perform these backups.

Creating snapshots using Plug‑in for SnapMirror to Tape: The plug-in automatically creates a snapshot for Full Backup. This snapshot is used as the base for subsequent Incremental and Differential Backups. To create snapshots for Incremental and Differential Backups, select the “Create New Snapshot” check box while creating the Backup Options Set.
Here “x-x-x-x” represents a hexadecimal number and “n” represents the snapshot sequence number (0 for Full Backup, 1 for Incremental Backup 1, 2 for Incremental Backup 2, and so on).
Using existing snapshots: The plug-in can also use existing snapshots for BLI backups. These snapshots must be named as follows:
snapshot_for_smtape.<any string>.n
Here “n” represents the snapshot sequence number (0 for Full Backup, 1 for Incremental Backup 1, 2, and so on).
To use existing snapshots for backups, do not select the “Create New Snapshot” check box while creating the Backup Options Set.
