What is it?

This is a simple Bash script I made to automatically backup my virtual machines on my server. It's working really well for me, but there is no guarantee it will work for you. The script retains a set number of backups before starting to rotate. The backups are named with a date and timestamp and the rotation-number.

Usage

Replace the made-up names with the name, disktype and diskfile of your real virtual machines.

NUMBACKUPS decides how many backups should be retained. The file rotate.txt keeps track of the rotation.

VMDISKDIR is the directory where the virtual machines are stored on the server, not the backup dir.

Also make sure to check and/or change the directories to match your machine.

Then simple put the script in a cronjob.
