lxc-snapshot(1) lxc-snapshot(1)
lxc-snapshot - Snapshot an existing container.
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]
lxc-snapshot creates, lists, and restores container snapshots.
Snapshots are stored as snapshotted containers under the contain‐
er's configuration path. For instance, if the container's configu‐
ration 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.
-c,--comment comment_file
Associate the comment in comment_file with the newly creat‐
ed 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 pos‐
sible in the case of overlayfs or zfs backed snapshots.
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 ER‐
ROR. 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 virtualiza‐
tion 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 previ‐
ously created container (via lxc-create).
--version
Show the version number.
lxc(7), lxc-create(1), lxc-copy(1), lxc-destroy(1), lxc-start(1),
