NAME

6       lxc-snapshot - Snapshot an existing container.

SYNOPSIS

9       lxc-snapshot {-n, --name name} [-c, --comment file]
10       lxc-snapshot {-n, --name name} {-d, -destroy snapshot-name}
11       lxc-snapshot {-n, --name name} {-L, --list } [-C, --showcomments ]
12       lxc-snapshot {-n, --name name} {-r, -restore snapshot-name} [-N,
13                    --newname newname]
14

DESCRIPTION

16       lxc-snapshot creates, lists, and restores container snapshots.
17
18       Snapshots are stored as snapshotted containers  under  the  container's
19       configuration path. For instance, if the container's configuration path
20       is /var/lib/lxc and the container is c1, then the first  snapshot  will
21       be  stored as container snap0 under the path /var/lib/lxc/c1/snaps.  If
22       /var/lib/lxcsnaps, as used by LXC 1.0, already  exists,  then  it  will
23       continue to be used.
24

OPTIONS

26       -c,--comment comment_file
27              Associate  the  comment  in  comment_file with the newly created
28              snapshot.
29
30       -d,--destroy snapshot-name
31              Destroy the named snapshot. If the named snapshot is  ALL,  then
32              all snapshots will be destroyed.
33
34       -L,--list
35              List existing snapshots.
36
37       -C,--showcomments
38              Show snapshot comments in the snapshots listings.
39
40       -r,--restore snapshot-name
41              Restore the named snapshot, meaning a full new container is cre‐
42              ated which is a copy of the snapshot.
43
44       -N, --newname
45              When restoring a snapshot, the last  optional  argument  if  not
46              given  explicitly  via  --newname is the name to use for the re‐
47              stored container. If the newname is identical  to  the  original
48              name  of  the container, then the original container will be de‐
49              stroyed and the restored container will  take  its  place.  Note
50              that  deleting the original snapshot is not possible in the case
51              of overlayfs or zfs backed snapshots.
