AAG Backup

  • Hi all I have 2 doubts on this can anyone please clarify:

    On primary for system database backup I have not selected copy only backup, will that be okie?

    On secondary while configuring Txlog backup If I select all databases backup plan is failing where as if I choose user databases backup it is running fine. Don't we have txlog bkp for system databases backups in AAG?

  • You must use COPY_ONLY when backing up a database on a secondary server. When backing up a database on the primary you can run a regular backup, or a COPY_ONLY backup. As to the transaction logs for system databases, not all system databases have transaction logs, and no, in general, they don't need to be backed up. For system databases I usually just run full backups.

  • you cannot do a log backup on the master database as it can only be in simple mode. That will be why the TLOG backup is failing for system databases (model and msdb may also be in simple mode).

    Full backups will suffice for system databases.
