The error message is stating that backup repository is corrupted or there might be an issue with backup infrastructure.


Network disruptions, hardware failures, improper backup repository detach, and third-party software can cause metadata and backup data to be locked, partially written, or even corrupted. To ensure data integrity at all times, the product periodically runs quick self-checks on backup repositories. In case a quick self-check finds symptoms of a problem in a backup infrastructure, such as incorrect time stamps on metadata and data files, or incorrect size of the files, the backup repository is locked to prevent any potential data corruption.

In many cases the issue is caused by incorrect time stamps on backup repository files, which can be caused by time difference between NAKIVO server and backup server or NAS.


  • Synchronize system time on both Nakivo server and the backup server / NAS
  • Run the full self-check to unlock the backup repository.

If the problem still persists, please contact NAKIVO Support for further investigation.


To avoid disrupting NAKIVO Backup & Replication processes and data corruption, add the application to the whitelist / exclusions list of the antivirus software running on the machine where the NAKIVO backup repository is set up.
