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 a container with container ID 200:
vzpbackup.sh --suspend=yes --compress=gz 200
Options:
--suspend=<yes/no> (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.
--exclude=<CTID>
Exclude specified CTID from being backed up. Most useful
while using --all
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.
--vzdir=<VZ Directory for VE_PRIVATE and VE_ROOT>
Instead of using the default VE_PRIVATE and VE_ROOT from the
default OpenVZ configuration (/etc/vz/vz.conf), create the
VE_ROOT and VE_PRIVATE in the directory given by the vzdir
option
Requirements:
- OpenVZ virtual machines using ploop as storage
- uuidgen to create IDs for backups
