Block-Level Restores

You can perform a file-level or a volume-level restore from a block-level backup.

The Job Results directory stores the result files that are created when a restore job is initiated. You must restart the SnapProtect services whenever you change the Job Results directory; otherwise, restore jobs fail because they continue to access the older Job Results directory.

Note: If you manually delete the tape copy of a full, incremental, or synthetic full block-level backup job before the data ages, you might not be able to restore data from the entire backup cycle, even though the other jobs are intact. Do not manually delete individual jobs before the data ages, because the jobs are interdependent.

High-Level Process for Block-Level Restores

  1. If you are performing a volume-level browse and restore, the entire volume is restored.
  2. If you are performing a file-level browse and restore, the following operations occur:
    • Depending on whether the metadata collection was enabled during backup, one of the following browse methods is selected if you perform a browse from the backup copy:
      • If metadata collection was enabled, a browse from the index is initiated.
      • If metadata collection was disabled, a live browse is initiated.
    • A browse from the index is initiated only when metadata collection was enabled if you perform a browse from the snapshot copy.
    • The selected files and folders are restored.
