Hi guys, I need to improve the backup strategy of my vms; At the moment I backup the machines once a week by stopping them, making a snapshot, exporting the xml descriptor file and backing up these files.
I would prefer a daily online backup solution that allows me to take a snapshot with a minimum downtime. That's why I was planning to switch from etx4 to btrfs; my project will be to pause the vm, dump the memory and the xml descriptor file, make a snapshot of the subvolume storing the qcow2 file and after that resuming the machine. does this project makes any sense? What about performance? Am I going to experience bad performance having qcow2 over btrfs? I read on some old (two years) posts that btrfs was having bad fragmentation when dealing with qcow2 files, is this still happening?
