Restore Corrupted File Backup (New Backup Format)

Situation

In case some part of file-level backup in the new backup format is accidentally deleted or lost from the backup storage, as of Backup Agent version 7.9.2 for Windows you can now try to restore the intact part of such backup dataset.

Solution

1. Open the Backup Agent software.
2. In Tools > Options menu, perform and save any change in any settings parameter. For example, you can increase logging level in the Logging tab from Low to High.
3. Click Apply. This action would update the Backup Agent service settings configuration file.
4. Reset the adjusted option back to a previous state. For example, you can reduce logging level in the Logging tab back from High to Low. Click Apply.
5. Open enginesettings.list configuration file which is:

• Located in the C:\ProgramData\Online Backup folder (this path could be different in case you are using branded company and/or product name).

6. Within that configuration file, change string value from <IgnoreMissingBlocks>false</IgnoreMissingBlocks> to <IgnoreMissingBlocks>true</IgnoreMissingBlocks>.
7. Save the changes made to the configuration file.
8. Open the Backup Agent again. If prompted, press "Accept" button on the "Unauthorized changes" automatic pop-up window.

Now you should be ready to retry the restore procedure.

Once the restore task is complete, all the files that cannot be restored due to damaged backup chain integrity should be listed and accounted for on the Backup History grid, which is available:

• In the Backup Agent on History tab.

• In Management Console (Reporting > Backup History, on file view tab of side panel for the completed restore task).
