Description
lxc-snapshot creates, lists, and restores container snapshots.
Snapshots are stored as snapshotted containers under the container's configuration path. For instance, if
the container's configuration path is /var/lib/lxc and the container is c1, then the first snapshot will
be stored as container snap0 under the path /var/lib/lxc/c1/snaps. If /var/lib/lxcsnaps, as used by LXC
1.0, already exists, then it will continue to be used.
