Sd-ext/Sdext2 partition Backup and Recovery from CWM Recovery

Hey guys, I have got a technique to Backup and recover your whole sdext2 / Sd-ext partition through Recovery in case you were unable to find a recovery to backup and recover this partition and as far as I know there is no single recovery out there till date that can directly Backup and restore this partition on Grand. So if you need this plese ask here.
