how to restore a guest OS from an rsync backup

[Tapas Mishra]

I took a backup of all the directories in an lvm.
This lvm which I am referring to above was having a Guest Operating System
the entire backup from the top most directory / is in a folder in a
USB hard disk.
Swap space I have not taken any backup.
So is there a way I can restore the Guest OS from this backup on  USB
bard disk which is on LAN at a remote location.
If yes then give me a link to it.
