Recommendations
Number of clients in a cell
In typical environments, 25 clients per cell is a recommended number.
Concurrent backup or restore sessions
Successful Application Recovery Manager backup and restore completion is influenced
by a number of factors imposed by non-Application Recovery Manager components,
including Microsoft Exchange Server and Microsoft Volume Shadow Copy Service.
One of the factors is timing, which in turn is impacted by environmental conditions
such as I/O loads, storage device activity, and concurrent Application Recovery
Manager actions.
To inhibit potential issues, it is recommended that you balance Application Recovery
Manager activity across the available activity or maintenance window. If you
encounter issues, review and possibly reduce concurrent Application Recovery
Manager activities such as concurrent backups or restores.
