HP 3PAR Application Software Suite for Microsoft Exchange Licenses - Manual (Page 15)

Multiple Host Backup Configuration
HP recommends that you use a separate Recovery Manager for Exchange backup server for the
mailbox databases on each HP 3PAR Storage System and that you execute commands from each
Recovery Manager backup server for each HP 3PAR Storage System. For example, if your Exchange
configuration involves two systems, System1 and System2, you should use two backup servers and
execute Recovery Manager commands for System1 from Backup Server 1, and execute commands
for System2 from Backup Server 2. If you have one HP 3PAR Storage System, you need just one
Recovery Manager backup server, and the -vs parameter is the server name of the Recovery
Manager backup server.
DAG Backup Configuration
If your Exchange 2010 configuration uses Database Availability Groups (DAGs), which replicates
mailbox database(s) across multiple HP 3PAR Storage Systems, HP recommends that you use a
master Recovery Manager backup server and use the other Recovery Manager backup servers as
verification servers (designated with the -vs parameter). Under this configuration, the Recovery
Manager for Exchange repository is centralized, and managed from one server. Keep in mind
that under this configuration, each verification server must have Recovery Manager Backup Server
installed in order to perform backups to media.
When implemented at a single site, you can use a single backup server, as shown in Figure 4
(page 15) and Figure 5 (page 16) . For implementations that span multiple sites, you must use one
backup server per site, as shown in Figure 6 (page 16) .
