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 overlayfs or zfs
              backed snapshots.

COMMON OPTIONS         top

       These options are common to most of lxc commands.

       -?, -h, --help

       -q, --quiet
              mute on

       -P, --lxcpath=PATH
              Use an alternate container path. The default is
              /usr/local/var/lib/lxc.

       -o, --logfile=FILE
              Output to an alternate log FILE. The default is no log.

       -l, --logpriority=LEVEL
              Set log priority to LEVEL. The default log priority is
              ERROR. Possible values are : FATAL, CRIT, WARN, ERROR,
              NOTICE, INFO, DEBUG.

              Note that this option is setting the priority of the
              events log in the alternate log file. It do not have
              effect on the ERROR events log on stderr.

              there is already a configuration file present in the
              previously created container (via lxc-create).
