Exchange database backup source for a Database Availability Group (DAG) backup
For backups of a Database Availability Group (DAG) you can choose whether to back up the active or the passive copy of the database. The client backs up and catalogs the selected database as if it were a local snapshot backup.
On the Attributes tab of the policy, for the backup source select one of the following:
| This option backs up the passive copy of a database or passive server if the database is all of the following: mounted, included in the backup selections list, and healthy. For a DAG, you must also configure a preferred server list. In that case, NetBackup backs up the passive copy on a server in the preferred server list, provided that the database meets the other criteria. If a database does not have any passive copies, then it is backed up on its active (and only) server. For example, the Public Folder database only has an active copy. A preferred server list is not required for any databases that only have an active copy. |
| This option backs up the active copy of a database or active server. The preferred server list is ignored. |
This option backs up the passive copy of a database or the passive server that is all of the following: mounted, included in the backup selections list, and healthy. For a DAG, you can also configure a preferred server list. In that case, NetBackup backs up the passive copy on a server in the preferred server list, provided that the database meets the other criteria. If the passive copy is not available and healthy, NetBackup backs up the active copy. This option is the default. |
