Using proxmox with ZFS storage pools, is it possible to restore an LXC container or QEMU Virtual Machine to an earlier snapshot (not the most recent snapshot) without losing or destroying any snapshots?
Attempting to do this using the Proxmox GUI presents an error message:
can't rollback, 'snapshotname' is not most recent snapshot on 'storage:vmname'
Asked another way, is it possible to have non-linear snapshots? For example, a tree of snapshots that looks like this, where there's a true "tree" with branches, and some snapshots have more than one child?
Multiple sources on the internet appear to indicate not (example 1 or example 2) but I know that's incorrect because I have done this :)
