HP Application Recovery Manager software Integration guide (March 2008)

backup session backing up a specific storage group can be running on the same
application system at once. Consequently, if you start a backup while another
one is in progress, the latter waits until the first one finishes.
Recommendations
• With EVA provider, an Exchange storage group should not reside on more than
four source volumes.
• Configuration with transaction logs residing on different source volume than stores
enables you to perform a rollforward recovery when only the stores are lost.
• Create one backup specification for each storage group and schedule them in a
row.
Writer stabilization
After each Microsoft Exchange Server Writer backup, Application Recovery Manager
by default waits 10 minutes for Microsoft Exchange Server Writer to stabilize. You
can disable this option or you can reduce the waiting time using the
OB2VSS_EXCHANGE_WRITER_STABILIZATION omnirc variable.
Consistency check
A backup of the Microsoft Exchange Server database is considered as successful
only if the consistency check of the replicated datafiles succeeds. To enable
consistency check, click on a created backup specification, right-click Microsoft
Exchange Writer in the Source tab, and then click Additional options.
The consistency check can also be run before instant recovery.
