After you restore a storage group or mailbox store from a CPS Exchange backup, you must restart the CPS Exchange backup job. Otherwise, the continuous protection job and any associated recovery points do not restart.
If you enabled recovery points to run at intervals between the full backups, you can restore individual messages or folders at a point in time when the recovery point was created. Even without recovery points, you can restore individual messages or folders from a full backup.
