HP 3PAR Recovery Manager Software - Manual (Page 133)

•
If you are using asynchronous Remote Copy, you can create HP 3PAR Recovery Manager
virtual copies even if policies on the servers do not match. If policies do not match, the virtual
copies use the policies on the Remote Copy backup server.
•
When running Remote Copy in a Synchronous Long Distance configuration, the virtual copies
on the synchronous and asynchronous periodic Remote Copy backup servers do not have the
exact same timestamp.
Support for GeoCluster for Microsoft Windows
HP 3PAR Recovery Manager for Exchange supports the use of both Remote Copy and HP 3PAR
GeoCluster Software for Microsoft Windows:
•
When synchronous mode Remote Copy is used with HP 3PAR Recovery Manager for Exchange
and GeoCluster, you can use HP 3PAR Recovery Manager to create virtual copies on both
the production system (the Remote Copy primary system) and the backup system.
•
When Synchronous Long Distance Remote Copy is used with HP 3PAR Recovery Manager
for Exchange and GeoCluster, you can use HP 3PAR Recovery Manager to create virtual
copies on all three systems: the production system (the Remote Copy primary system), the
synchronous mode backup system, and the asynchronous periodic mode backup system.
Setting Up Remote Copy Volume Groups for Mailbox Databases/Storage
Groups
1. Identify the virtual volumes that contain the mailbox database/storage group and log files to
be copied.
2. Create one (and only one) Remote Copy volume group per mailbox database/storage group.
3. Add the virtual volumes belonging to the mailbox database/storage group files and log files
to the primary Remote Copy volume group, and add the associated secondary virtual volumes
to the secondary volume group on the backup server.
CAUTION: The relationship between mailbox databases/storage groups and Remote Copy
volume groups is 1:1.
•
You must add mailbox database/storage group files to a primary Remote Copy volume
group for Remote Copy to function.
•
You must add files from only one mailbox database/storage group to one primary volume
group.
◦ Do not disperse files from one mailbox database/storage group over multiple primary
Remote Copy volume groups.
◦ Do not add files from multiple mailbox database/storage groups to the same Remote
Copy volume group.
If the system fails to meet these requirements, it may result in data corruption and loss.
4. Synchronize the Remote Copy primary and secondary volume groups.
Recovering a Mailbox Database/Storage Groups from a Remote Copy
Backup Server
If a mailbox database/storage group crashes at the site that holds the production system (the
Remote Copy primary system), you can recover the data from the backup server at the remote site
as long as it is set up in an identical manner to the original production server.
