HP 3PAR Recovery Manager Software for Microsoft SQL Server Licenses - Manual (Page 29)

If you specify an expiration time for a remote virtual copy:
•
If Remote Copy is set up in asynchronous periodic mode, Recovery Manager sets the expiration
time for the remote virtual copy on the Remote Copy backup server only, not for the virtual
copy created on the primary server.
•
If Remote Copy is set up in synchronous mode, Recovery Manager sets the expiration time for
both the virtual copy on the primary server and the remote virtual copy on the Remote Copy
backup server.
For more information, see the HP 3PAR Remote Copy Software User’s Guide.
The expiration-based policy option is only available if your HP 3PAR Storage System is running
HP 3PAR InForm Operating System Software 2.3.1 or above.
Retention Time Restrictions
If you have a Virtual Lock license, you can set a retention time for virtual copies. The instance or
database and the associated virtual copies created within the retention period cannot be removed
during the retention period.
When setting a retention time, keep in mind the following restrictions:
•
You must have a Virtual Lock license to set retention times.
•
The minimum retention time is 1 hour; the maximum is 43,800 hours/1,825 days (5 years).
The default maximum retention time is 336 hours (14 days).
•
You can set a retention time for both numeric-based and expiration-based policies.
•
The retention time cannot exceed the default maximum retention time set for the Storage Server.
•
The retention time cannot be longer than the expiration time (if the policy is expiration-based).
•
If you create a remote virtual copy and Remote Copy is set up in asynchronous periodic mode,
the retention time is applied to the remote copy on the Remote Copy backup server only. If
Remote Copy is set up in synchronous mode, the retention time is applied to both the remote
copy on the Remote Copy backup server and the virtual copy on the primary server.
•
After the retention time is set, it can be increased, but it cannot be removed or reduced.
Setting Recovery Manager Policies
1. In the node tree pane, right-click the instance you want to configure and select Policy.
2. Depending on whether you want to set a maximum number of copies or you want to set an
expiration time frame, do the following in the Policy Setup dialog box:
Follow these steps: To set:
Maximum number of virtual copies 1. Select the Numeric radio button.
2. In the Maximum Instance level Virtual Copies and Maximum Database
level Virtual Copies text boxes, enter the desired maximum for each as a
number between 1 and 500.
3. To remove the oldest virtual copy each time a copy above the maximum
is created, check the Remove the oldest Virtual Copies checkbox.
To keep the oldest virtual copy (and therefore prevent new virtual copies
from being made after the maximum number is reached), unselect the
Remove the oldest Virtual Copies checkbox.
Expiration time frame for virtual
copies 1. Select the Expiration radio button.
2. In the Expire In text box, enter the number of hours or days after which
you want Recovery Manager to remove each virtual copy. The maximum
expiration period is 43800 hours/1825 days (5 years).
3. In the drop-down list, select either Hours or Days.
