Using Multiplexing with Microsoft Exchange Backup Jobs

Use the following registry key to control over how Arcserve Backup backs up Exchange data when using multiplexing. You can back up Exchange storage groups or mailbox database on the same server sequentially, with one sub-job, or simultaneously. You must set this registry value on the backup server running the multiplex job.

Note: In prior versions of Arcserve Backup, all storage groups on the same server were backed up simultaneously when multiplexing was enabled.
