September 8, 20241 yr I FINALLY got my GPU passthrough and everything working and DESPERATELY want to snapshot it so I know I have a good, working baseline and, when I click "create snapshot", I'm told there is "insufficient storage for snapshot"... ...uh...wut? Insufficient storage WHERE, exactly? I have ~16.5TB of free space on the array, almost 500GB of free space in the ZFS array...where is it trying to store the snapshot? I'm thinking there's some setting I have to tweak or something but this makes no sense...I have storage space all over the place. lol That's beta software for ya. Hahaha Edited September 8, 20241 yr by rmp5s

September 8, 20241 yr Community Expert Solution Then you can't make snapshots, it's "layering" vdisks.

September 8, 20241 yr Community Expert For a physical disk you'll want to image it just like a phisical machine. Edited September 8, 20241 yr by Kilrah
September 8, 20241 yr Author Just now, Kilrah said: Then image the physical disk. Yea, I'm looking up the "manual snapshot" procedure. DD the disk and backup the VM itself...don't remember that last part. I guess that'll work... I did all this because I had my boot drive die (again) and thought, "I'll virtualize it all so next time it happens, it won't matter." Guess I could just put the vdisk on that SSD...dunno how well that would perform...

So you need to backup the disk, you can you DD to create an image dd if=/dev/name of=/path to image. You need to backup the XML and NVRAM both stored in /etc/libvirt/qemu. Future enhancement is to look at backups within Unraid.
