OVZ-Backup

OVZ-Backup is a small python script that creates ploop snapshots of OpenVZ containers and backs them up with rsync. It can either back up all OpenVZ containers, or be given a list of container IDs that it should either back up or exclude. All errors from OpenVZ and rsync are logged with syslog. OVZ-Backup can also take a list of users or email addresses that should be notified when errors occur.

To send error messages using email you must first set up a local SMTP relay that can forward email to an SMTP server.

More information and instructions for configuring an SMTP relay is available here: http://andsk.se/2014/09/28/backing-up-openvz-ploop-snapshots/

Usage

ovz-backup [OPTIONS] snapshot_path [conf_path]

snapshot_path

conf_path

Sets a separate path for storing configuration backups.
The snapshot path is used by default.

-h, --help

Show help message

-i CTIDS [CTIDS ...], --ctids CTIDS [CTIDS ...]

List of CTIDs to either back up or exclude.

-e, --exclude

Back up all containers except those provided in the CTID list.

-d, --debug

Print out all backup commands instead of executing them. No changes will be made.

-v, --verbose

-t MAILTO, --mailto MAILTO

Mail address to send error messages to.

Examples

Only back up the containers 101, 102, and 103. Store configuration files in a separate directory. In this example a double dash (--) is needed to tell OVZ-Backup to stop parsing arguments as CTIDs and use the final two arguments as the backup path.

ovz-backup.py -v -i 101 102 103 -- backupuser@backup.example.com:/path/to/backup/folder/snapshots/ backupuser@backup.example.com:/path/to/backup/folder/conf/

Back up all containers except 101 and send error messages to user@example.com and admin@example.com.

ovz-backup.py -t user@example.com -t admin@example.com -i 101 -e -v backupuser@backup.example.com:/path/to/backup/folder/

Back up all containers and send error messages to root. Do a test run without creating snapshots or writing any data.

ovz-backup.py -t root -d -v backupuser@backup.example.com:/path/to/backup/folder/
