3PAR Management Plug-In and Recovery Manager 2.1.0 for VMware vSphere User’s Guide
When enabling the expirable virtual copies option, you must specify the length of time (Days, Months, Years) from the current time that the virtual copies are to expire. You can set the expiry period up to 1825 days.
NOTE: Expirable virtual copies are not included in the maximum count.
When enabling expirable virtual copies, you also have the choice of specifying how existing non-expirable copies are handled.
◆Delete the oldest when count reaches maximum. This is the recommended setting.
Select this option if you plan to create both expirable and non-expirable virtual copies. All non-expirable copies (new and existing) will be counted against the maximum count with the oldest being deleted as it exceeds the maximum count. The RMVMware CLI and Scheduler have the option of overwriting the default policy. However, virtual copies created using the GUI interface are bound by the default policy.
◆Phase out non-expirable virtual copies (Advanced)
Select this option if you plan to mostly create expirable virtual copies and want to eventually phase out older non-expirable virtual copies. In this case, whenever a newer expirable virtual copy is created, the oldest non-expirable copy will be deleted. You can still create non-expirable virtual copies, as long as the aggregate count is below the policy maximum.
NOTE: If all non-expirable virtual copies are in valid retention and have already reached the maximum count, choosing the Enable expirable virtual copies option with the Phase out non-expirable virtual copies setting will fail. If this happens, choose the Delete the oldest when count reaches maximum option instead.
