VMware Data Recovery backups fail with the error: failed, error -2241 (Catalog File invalid/damaged) (1015901)

Symptoms

You are experiencing these issues with VMware Data Recovery (VDR):
  • Cannot perform the backup
  • Backup fails
  • You see the error:
     
    failed, error -2241 (Catalog File invalid/damaged)

Cause

This issue occurs if the VDR catalog files are corrupt.

Resolution

To resolve the issue:
  1. Recreate the catalog files:
    1. Verify that there are no operations running on the appliance.
    2. Stop the datarecovery service. See  Restarting the datarecovery service on a VMware Data Recovery appliance (1036768)

         service datarecovery stop
    3. Delete the following files in the dedupe store mount point:
      • /{dedupe mount point}/VMwareDataRecovery/BackupStore.cat
      • /{dedupe mount point}/VMwareDataRecovery/BackupStore.cat.bak

        Note: The restore points are temporarily deleted.

    4. Start the datarecovery service. A restart of the VDR virtual machine will similarly restart the service.

            service datarecovery start
    5. Run an integrity check on the destination directory to recreate the catalog files. The integrity check rebuilds the BackupStore.cat files, and repopulate VDR with all restore points.

      Note: The integrity check fails because the catalog files have just been deleted. This is an expected behavior. However, the catalog files are created in the background, which might take a long time. You can monitor the rebuilding process by running this command from the VDR command line: 

         watch -n1 -d "ls -lt /{dedupe mount point}/VMwareDataRecovery/".

      If you cannot observe any progress, it is most likely due to the re-catalogue process not starting. This may be caused due to locks on the deduplication store. For more information, see VMware Data Recovery Integrity Check fails with the error: Trouble reading from destination volume, error -2241 (1018060).

  2. Ensure that the VDR appliance does not have any hot-added vDisks from other virtual machines attached to it. To verify this, click Edit Settings in the VDR appliance.
  3. Upgrade to the latest version of VDR. For more information, see VMware Data Recovery Documentation.
