HP 3PAR Recovery Manager Software for Microsoft SQL Server Licenses - Manual (Page 28)

Updating Registration after Server Modification
If you modify a registered instance's configuration (e.g., you create a new database under that
instance), you must rescan the instance to update the registration.
To rescan an instance:
1.
Right-click the MS SQL Server node.
2. Select Rescan Server Configuration.
Unregistering a SQL Server Instance
To remove a server instance from the list of registered servers:
1.
Right-click the MS SQL Server node.
2. Select Register Server.
3. Unselect the Register checkbox for the server instance you are deleting.
4. Click OK.
Setting the Recovery Manager Policy
Recovery Manager applies policy settings at the instance level; therefore, each instance can have
its own policy. In addition, you can configure individual virtual copies with their own policy settings.
How Recovery Manager Policies Work
The Recovery Manager policy-setting feature allows you to:
•
Specify either a numeric-based or expiration-based policy for each instance and database on
a selected SQL server
•
Specify a retention time during which the instance or database and its virtual copies cannot
be removed (if you have a Virtual Lock license)
NOTE: Modifications you make to an existing policy are not retroactive. Virtual copies created
under a previous policy (whether numeric or expiration-based) retain the policy setting under which
they were created.
Numeric-Based Policies
If you specify a numeric-based policy, you can modify the maximum number of virtual copies
allowed per database and per instance. By default, Recovery Manager allows you to create a
maximum of 10 virtual copies per database and 10 virtual copies per instance.
The numeric-based policy also enables you to set Recovery Manager to automatically remove the
oldest virtual copy for each database and instance, after the maximum limit of virtual copies is
reached, before creating a new virtual copy. If you do not choose to automatically remove virtual
copies when required in order to create a new virtual copy, you must manually delete old virtual
copies before you can create new copies.
NOTE: A virtual copy must be unmounted to be removed. If the oldest virtual copy is mounted,
a new virtual copy is not created until the oldest copy is unmounted.
Expiration-Based Policies
If you choose an expiration-based policy, you can set Recovery Manager to automatically remove
virtual copies after a specified period of time has elapsed.
