Job fails with Filegroup backups can only be performed on databases configured to support Log backups.

 I recently started with a new company and inherited Backup Exec 2010 R3. There was a job that was on hold for awhile due to space issues, that I placed back into scheduling. Now it fails with "Filegroup backups can only be performed on databases configured to support Log backups". The link V-79-57344-37911 gives absolutly no direction. This used to work and nothing has changed on the SQL server, so I am not sure what to do. Yes, I can see the filegroups are checked, but again it used to work. The job contains Enterprise Vault and the SQL server used for it.
