Hi,
We are finding a way to do rollback for qcow2 in production environment,
But we can't ensure the below way will work well, and user data are safe.
for example,
snap0.qcow2 -> snap1.qcow2 ->snap2.qcow2 -> active.qcow2
rollback to snap1 using convert && rebase -u:
1. qemu-img convert -O qcow2 snap1.qcow2 rollback.qcow2
2. qemu-img -u -b snap2.qcow2 rollback.qcow2
Test pass with data. But in theory, could someone give me a positive answer?
Appreciate to get your reply!
Best Regards.
