Hi,to have consistency, we need to freeze/unfreeze the filesystem if qemu-agent is available. (Proxomox implemented it with backup and snapshots)

qm agent fsfreeze-freeze

do the snasphot of all drives

qm agent fsfreeze-thaw

Good idea

mhubig commented 6 years ago

You could use something like this instead of rbd snap create to make the snapshot:

pvesh create /nodes/pve-node-01/qemu/100/snapshot -snapname test -vmstate 0

Hi, Thanks for the idea. I'm reworking the new version. Your solution does not let you know when the snapshot is over. You could analyze the task but with the bash commands it's complicated. I'm developing a cli in a new language. The new version uses APIs and takes Proxmox snapshots.

Best regards

Good news, I'm really looking forward to it! Are you using Python?

BTW: Thank you for the good work!
