Exchange 2010 DAG backup issue
Hello. I've got a strange backup problem (Backup Exec 2012 SP4 with hotfix 215906 and 216746). I do full backup once a week and incremental backups every 6 hours and use GRT. Everything was OK until about 3 weeks ago. Full backup works fine but incremetal backups work only for 3-4 days. After that Backup Exec starts to fail incremetal backup of one database with the error V-79-57344-862 - The Backup Exec Agent for Microsoft Exchange was not used to create the last full backup of this database. You must use the Exchange Agent to run a full backup before you run a differential or incremental backup. And another error is 'JET_errDatabaseDirtyShutdown This error is obsolete and has been replaced by JET_errDatabaseDirtyShutdown. ' But there are no problems with the database. It mounts and works OK. The members of the DAG weren't even rebooted. All other databases (the second mailbox database and 2 public folders databases) backup perfectly. If I make full backup again this fixes the issue for another serveral days.
