Configuring Manual or Automatic Selection of the Backup Source

In a DAG environment, you select the Exchange server backup source to be a single server (manual selection) or the next available passive server (automatic selection).

Manual selection

For each database, configure backups to run on any one of the available DAG servers.

Manual server selection allows backups of Mailbox and Public Folder databases.

Automatic selection

Determine from which server the backup is run.

  • Because database-centric processes require a lot of resources, running a backup job on the active server might slow down other processes. By default, backups run on the first available passive server.
  • If there are no passive servers available, you can configure backups to run on the active server.
  • In addition, you can configure backups to run on the server with the highest number of activation preferences. This ensures the backup runs on a server that is least likely to become active in a failover case.

Automatic server selection allows backups of Mailbox and Public Folder databases.
