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.
