OpenVZ Container Backup - for containers using ploop storage

The scripts are meant to provide a backup solution to backup containers that use ploop storage. Traditional storage is not supported by the scripts. The scripts are based on the OpenVZ wiki page regarding image backup: http://openvz.org/Ploop/Backup

BACKUP

vzpbackup.sh [--suspend=<yes/no>] [--backup-dir=<dir>] [--compress=<no/bz/pz/gz/xz>] [--all] CTID CTID

Backup a container with container ID 200:

vzpbackup.sh [Options] 200

Options:

--suspend=yes (Default: no)

This will result in calling vzctl snapshot without the
parameter "--skip-suspend" resulting in a snapshot of
the running container being included in the backup.
If you restore that backup using vzprestore.sh, you can
resume the container after the restore has finished.

--backup-dir=<Directory> (Default: /store/vzpbackup)

Parameter to change the default backup directory. Either
use the parameter or change the script.

--compress=<Compression> (Default: no(ne))

Allows you to compress the resulting archive file using either
bzip2, pigz, gzip or xz to save some disk space.

--all

This will backup _all_ containers that are currently
configured on the host (Every container returned by
"vzlist -Hoctid"). Currently there is no option to
exclude specific CTIDs from the backup.

Restore

vzprestore.sh --archive=<ContainerBackupArchive> --container=<Container to restore to>

Restore a backup to a new container 250:

vzprestore.sh --archive=/store/vzpbackup/vzpbackup_200_test.host.tar --container=250

Options:

--archive=<PathToBackupArchive> (Default: None)

Specify the backup archive to be restored.

--container=<ContainerID> (Default: None)

Specify the container that the backup shall be restored to.

--confirm=<yes/no>

Confirm what is being done prior execution.

--delete-backup-snapshot=<yes/no>

Delete (switch to it and delete it) the snapshot created during backup creation.
    Note: Any memory dumps will be lost if you do it at this stage after restoring
    the container.
