Some time ago, I moved the folder /usr to its own partition. Before this it had lived in the / partition which has a **btrfs filesystem.
Accidentally, I formatted my /usr partition from my Windows XP OS.
Through Xbuntu LiveCD I can see there are three snapshots, two of which contain my old /usr.
I am wondering if I can recover my /usr from the snapshots taken by btrfs?
Can I just copy the contents of the snapshot to /usr?
