Problem with the Backup Infrastructure

Product version: 9.3

Last modified: 25 May 2020


The error message states that the Backup Repository is corrupted or that there might be an issue with the 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, NAKIVO Backup & Replication periodically runs quick self-checks on Backup Repositories. If a quick self-check finds symptoms of a problem in a backup infrastructure, such as incorrect timestamps on metadata and data files, or incorrect file size, the Backup Repository is locked to prevent any potential data corruption.

In many cases, the issue is caused by incorrect timestamps on Backup Repository files, which can be caused by a time difference between the NAKIVO Backup & Replication server and the backup server or NAS.


  • Synchronize system time on both the NAKIVO Backup & Replication server and the backup server/NAS

  • Run a full self-check to unlock the Backup Repository.

If the problem persists, contact NAKIVO Support.


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