Does anyone have a good complete strategy for backing up a bunch of virtual machines running under VirtualBox?
I intend to run a handful of virtual machines on a single hardware platform and back them up nightly to external disks, which will be taken off site every weekend in rotation.
(Just to clarify, I don't intend to shut the machines down during this process, if I can avoid it)
Am I right in thinking I can just write a script which, each night, creates a snapshot, copies the 'main' disk image to the external media, then removes the snapshot again?
Better ideas are much appreciated!
