Repairing Backup Repository

In case an immutable backup or the Backup Repository itself is corrupted, it is possible to initiate a repair process. During this process, NAKIVO Backup & Replication attempts to revert the Backup Repository or a specific backup to its uncorrupted state.

Refer to the following topics:

Running the Repair Process for a Backup Repository

To run repair for a Backup Repository, do the following:

  1. Go to Settings > Repositories and hover over the name of the Backup Repository.

  2. Click ••• and select Repair. Alternatively, you can click on the name of the Backup Repository and then go to Manage > Repair to start the repair process.

    Note

    The Repair option is only available in the following cases:

    • Non-immutable recovery points have been removed from the Backup Repository of the Local folder or Amazon S3 type.

    • The local Backup Repository is inaccessible and meets the conditions specified in the feature requirements section.

    • A forever incremental repository becomes corrupted due to space reclaim interruption. This may occur as a result of rebooting the transporter assigned to the repository or disconnecting storage while space reclaim is in progress.

  3. Select the desired options from the following:

    • Overwrite repository metadata: When this option is selected, the metadata file is overwritten even if it is present and valid. If the metadata file is not present, the new file is then created regardless of whether this option is selected or not.

    • Overwrite backup objects: When this option is selected, the locked backup objects are overwritten with the immutable data during the repair process.

    • Verify backup objects: When this option is selected, NAKIVO Backup & Replication runs verification of the backup object after the repair process is completed. When this option is not selected, NAKIVO Backup & Replication runs automatic self-healing after the repair process is completed.


      Note
      When initiating a repair for a Forever Incremental repository that has become corrupted as a result of space reclaim interruption, the following dialog will appear instead.

Running the Repair Process for a Specific Backup Object

To run a repair for a specific backup object located in a Local Folder or Amazon S3 type of Backup Repository, do the following:

  1. Go to Settings > Repositories and can click on the name of the Backup Repository. Hover over the name of the backup and click Repair to start the repair process. Alternatively, you can click on the name of the backup and then click Repair.


    Note

    You can also perform the Repair process for a backup object when all files except immutable files were manually deleted from the Backup Repository. The Repair option is only available in the following cases:

    • The Backup Repository is inaccessible, was created in Amazon S3, and has Object Lock enabled.

    • The local Backup Repository is inaccessible and meets the conditions specified in the feature requirements section.

  2. Optionally, select the Verify backup object option. When you select this option, NAKIVO Backup & Replication runs verification on the backup object after the repair process has completed. In case Verify backup object is not selected, NAKIVO Backup & Replication runs automatic self-healing after the repair process is finished.

  3. Click Repair to begin the repair process.
