HP 3PAR Recovery Manager Software for Microsoft SQL Server Licenses - Manual (Page 74)

Setting Up Remote Copy
1. Install and configure Remote Copy. For more information, see the HP 3PAR Remote Copy
Software User’s Guide.
NOTE: Be sure to configure the Remote Copy backup server with the same names, structure,
and Windows authentication mode settings as the primary server.
2. After you have set up Remote Copy on two HP 3PAR Storage Systems, create a Remote Copy
volume group for testing purposes.
3. Configure the Remote Copy volume group for synchronization either in synchronous mode or
in asynchronous periodic mode with a period value of zero.
Support for Remote Copy Modes and Policies
Recovery Manager supports Remote Copy in synchronous and asynchronous periodic mode.
•
If you are using synchronous Remote Copy, the policies on the production system (the Remote
Copy primary system) and the Remote Copy backup system must match. If the policies do not
match, Recovery Manager cannot create virtual copies on a synchronous Remote Copy system.
However, if you manually specify an expiration value, a retention value, or both when you
create a virtual copy, Recovery Manager creates the virtual copy on a synchronous Remote
Copy system even if the policies on the Remote Copy primary and backup servers do not
match.
NOTE: For more information on specifying values at the time you create virtual copies, see
the description of the RMSql create command in “Using the Recovery Manager CLI”
(page 42) .
•
If you are using asynchronous periodic Remote Copy, you can create 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.
•
If you are running Remote Copy in a Synchronous Long Distance configuration, the virtual
copies on the synchronous Remote Copy backup servers have the same timestamp. The virtual
copies on the asynchronous periodic Remote Copy backup servers do not have the same
timestamp.
