Specifying the Volume to Back Up
To perform block-level backup operations on a snapshot-capable volume, configure the volume as subclient content. The volume that you back up can be a from a local disk or from a hardware snapshot engine that is supported by Commvault.
The Phases of Block-Level Backup Operations
Block-level backup operations have the following phases:
Both of these phases have several sub-phases. For native (CVBF/LVMs) backup operations, both the phases run as a single job. For hardware snapshots, the snapshot copy phase and the backup copy phase run separately as two jobs.
Snapshot Copy Sub-Phases
Backup Copy Sub-Phases
For native backup operations, a spool copy is automatically configured, and the snapshots are deleted after the backup copy job completes. For hardware backups, the snapshots are deleted according to the storage policy settings.
File Indexing After Block-Level Backup Job Completion
If you enable the Index files after backup option, files are cataloged offline as a separate job after the block-level backup completes.
