lxc-snapshot: Snapshot an existing container.


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} [ newname]


lxc-snapshot creates, lists, and restores container snapshots.

Snapshots are stored as snapshotted containers under a private 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 configuration path /var/lib/lxcsnaps/c1.


-c,--comment comment_file
Associate the comment in comment_file with the newly created snapshot.
-d,--destroy snapshot-name
Destroy the named snapshot.
List existing snapshots.
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.
When restoring a snapshot, the last optional argument is the name to use for the restored container. If no name is given, 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 aufs, overlayfs or zfs backed snapshots.
