<para>
|

Snapshots are stored as snapshotted containers under the container's 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 the path <filename>/var/lib/lxc/c1/snaps</filename>.
|
|
If <filename>/var/lib/lxcsnaps</filename>, as used by LXC 1.0, already exists, then it will continue to be used.

<para> When restoring a snapshot, the last optional argument if not given explicitly via <command>--newname</command> is the name to use for the restored container. If the newname is identical to the original name of the container, then the original container will be destroyed and the restored container will take its place. Note that deleting the original snapshot is not possible in the case of overlayfs or zfs backed snapshots.</para>
