NAME

   lxc-snapshot - Snapshot an existing container.

SYNOPSIS

   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

   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

   -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

   These options are common to most of lxc commands.

   -?, -h, --help
          Print a longer usage message than normal.

   --usage
          Give the usage message

   -q, --quiet
          mute on

   -P, --lxcpath=PATH
          Use an alternate container path. The default is /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, ALERT, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG, TRACE.

          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.

   -n, --name=NAME
          Use container identifier NAME.  The container identifier format is an alphanumeric string.

   --rcfile=FILE
          Specify the configuration file to configure the virtualization and isolation functionalities for the container.

          This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create).

   --version
          Show the version number.
