Support for Remote Copy Modes and Policies

Recovery Manager supports Remote Copy in synchronous mode 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.

If you manually specify an expiration value, or a retention value, or both when you create a
virtual copy, Recovery Manager creates the virtual copy on a synchronous Remote Copy
system if

the policy on both the Remote Copy primary server and backup servers is an expiration
based policy and

all the policy values including retention values match

You can specify only the retention value when you create a virtual copy on synchronous Remote
Copy system, if the policy on both the Remote Copy primary servers and backup servers is
numeric and all the policy values, including retention values, match.

NOTE:

For more information on specifying values at the time you create virtual copies, see

the description of the HpRmCli Sql create command in

“Using the Recovery Manager

CLI” (page 54)

.

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.

Support for GeoCluster for Microsoft Windows

HP 3PAR Recovery Manager for SQL 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 SQL
and GeoCluster, you can use Recovery Manager to create virtual copies on both the production
system (the Remote Copy primary system) and the Remote Copy backup system.

When Synchronous Long Distance Remote Copy is used with HP 3PAR Recovery Manager
for SQL and GeoCluster, you can use Recovery Manager to create virtual copies on all three
systems: the production system (the Remote Copy primary system), the synchronous mode
Remote Copy backup system, and the asynchronous periodic mode Remote Copy backup
system.

Setting Up Remote Copy Volume Groups

Setting Up a Remote Copy Volume Group for Databases

1.

Identify the virtual volumes that contain the database and log files to be copied.

2.

Create one (and only one) primary Remote Copy volume group per database.

NOTE:

Recovery Manager supports multiple databases in one Remote Copy volume group

if all the databases in the group belong to the same instance.
