Last Modified:


After applying a hot-fix the "Method not found" error pops up when working with the backup console.

You encounter the error below when browsing the Backups list and job settings, deleting backups, etc.

Method not found: 'Int32 Veeam.Backup.Common.get_MinRemovedVMRetentionDays()'

There is most likely a conflict between *.dll versions. Go to the folder where Veeam Backup & Replication is installed and make sure all *.dll files have the same version:

The conflict can happen if the hotfix was previously installed over the incorrect version, and new methods from the new version are not recognized in the earlier version.


To address the issue, follow the tasks below:


  1. Back-up VeeamBackup SQL database. To be on the safe side, you can use Management Studio.

  2. Upgrade to the latest build of Veeam Backup & Replication.
  3. Re-apply the hotfix.
