HP 3PAR Application Software Suite for Microsoft Exchange - Manual (Page 38)

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
When you set a retention time for virtual copies, Recovery Manager creates a virtual lock on the
mailbox database/storage group and its virtual copies. The mailbox database/storage group and
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 an HP 3PAR 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 retention time on a system 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 maximum retention time set for the HP 3PAR Storage
System.
•
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 backup server only. If Remote Copy is
set up in synchronous mode, the retention time is applied to both the remote copy on the
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 mailbox database/storage group 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 Virtual Copies kept in Storage System text box, enter the desired
maximum 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), uncheck the Remove the
oldest Virtual Copies checkbox.
Expiration time frame for
virtual copies 1. Select the Expiration radio button.
2. In the Default Expiration Time text box, enter the number of hours or days after
which you want Recovery Manager to remove each virtual copy.
The minimum expiration period is 1 hour; the maximum is 43,800 hours/1,825
days (5 years).
3. In the drop-down list, select either Hours or Days.
3. To modify the default retention time for the mailbox database/storage group and its virtual
copies, enter the number of hours or days you want to keep the mailbox database/storage
group and its contents.
The minimum retention period is 1 hour; the maximum is 43,800 hours/1,825 days (5 years).
