<para>

<command>lxc-snapshot</command> creates, lists, and restores

container snapshots.

</para>

<para>

Snapshots are stored as snapshotted containers under a private configuration path. For instance, if the container's configuration path is <filename>/var/lib/lxc</filename> and the container is <filename>c1</filename>, then the first snapshot will be stored as container <filename>snap0</filename> under configuration path <filename>/var/lib/lxcsnaps/c1</filename>.
