volume group have changed. This represents a case where the target volumes have been modified
over time, but you want to revert them back to their old state captured in the source snapshot set.
When a volume group is restored,
• source_time is set to the source_time of the snapshot set it is being restored from.
A volume group that is acting as the destination in a replication session cannot be restored.

Description
Refresh the contents of a volume group (the target volume group) from another volume group in
the same family. A backup snapshot set of the target volume group will be created before refresh is
attempted. This behavior can be overridden by setting the create_backup_snap property to false.
The profile for the backup snapshot set will be auto-generated, unless a custom profile is specified.
The auto-generated profile only initializes the name to an auto-generated, unique value. Other
optional parameters are not specified. The table below outlines supported modes of operation and
resulting updates to source_id and source_time attributes of protection_data. |Target volume
