Failed to synchronize Details: Unsupported method.

After updating our Cloud Connect Infrastructure to the latest Veeam Patch our customers reported the following error when synchronizing their repository:

Failed to synchronize <RepoName> Details: Unsupported method.
Agent failed to process method {Stg.SetGlobalOptions}.

Restarting services as well as rebooting the whole server did not help to solve. I had to reapply all settings by doing the following procedure:

  1. On your Veeam B&R Console go to “Backup Infrastructure” and click on “Backup Repositories”
  2. Choose your Repository from the list and choose “Properties”
  3. Go trough all the settings and click finish.

After the wizard has completed your customers should be able to continue their backups.


Source backup file has different block size. Expected block size: 512

If you configure a backup copy job within Veeam and get this error it quite likely happens because you have chosen “LAN Target” for storage optimization on your basic backup job. Jobs with this settings have another block size and will not process with copy jobs – even not with Veeam Cloud Connect.

Error you will see:


The only solution that worked for me was to perform a new active backup (on the source job) or delete all the backup files and start over (in case you do not have enough space for additional full backups).


Change “Storage optimization” to local target and start your full backup. After all your copy job will work like it should.
