NAME         top

       lxc-snapshot - Snapshot an existing container.

SYNOPSIS         top

       lxc-snapshot -n, --name name [ -c, --comment file ]

       lxc-snapshot -n, --name name -d, -destroy snapshot-name

       lxc-snapshot -n, --name name -L, --list  [ -C, --showcomments  ]

       lxc-snapshot -n, --name name -r, -restore snapshot-name [ -N,
       --newname  newname ]

DESCRIPTION         top

       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.

OPTIONS         top

       -c,--comment comment_file
              Associate the comment in comment_file with the newly created
              snapshot.

       -d,--destroy snapshot-name
              Destroy the named snapshot. If the named snapshot is ALL, then
              all snapshots will be destroyed.

       -L,--list
              List existing snapshots.

       -C,--showcomments
              Show snapshot comments in the snapshots listings.

       -r,--restore snapshot-name
              Restore the named snapshot, meaning a full new container is
              created which is a copy of the snapshot.

       -N, --newname
              When restoring a snapshot, the last optional argument if not
              given explicitly via --newname 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 aufs, overlayfs or zfs backed
              snapshots.
