Hi,
I have started to consolidate all the services of my home infrastructure, which were spread over several physical machines but not very logically, into VMs which run on my new core server. The core server is a Xeon with 32GB RAM, 6x3TB running ZFS/RaidZ2 and a 128GB SSD. The VM disk images are located on the SSD for performance but, of course, I would like to have also safety, so I would like to create a copy of every VM's disk image at least once a day and store a history of those on the array. I have been googling quite a bit and found a ton of whitepapers but no simple tutorial on how to do that. Frankly, I'm not interested in learning to fully understand the inner workings and coding concepts of e.g. qemu-livebackup. That's not my topic. I simply want to do backups of my VMs.
Can anybody point me to a simple tutorial on how to get a clean copy of a VM's disk image without shutting the VM down for that?
