[linux-lvm] restoring filesystem state using snapshot

[kanika nema]

hi,
i want to restore the filesystem state using only the snapshot taken by LVM 
ie without taking a full backup.
is this possible to do? i read all the lvm commands, but there is no command 
to actually restore the entire filesystem back to the state it was in, when 
the snapshot was taken.
though the old files' state can be viewed using the snapshot volume, i want 
to take the filesystem back to the prev state.
Please tell me if this can be done. its urgent.
thx,
K
