As in: bare metal disaster recovery restores, using a recovery boot iso, and restore a system from scratch to bootable state. It's not a tool for that, right? Currently there's no such integrated tool, but honestly I do not think that would be *that* hard to make. We have a similar process in plan for VMs, i.e., boot a VM with a live system and the backup disks as read only disks plugged in. Note also that the client has already support to mount an archive of a backup locally over a FUSE filesystem implementation - maybe that would help already. > > - I guess with VMs etc, the backup will use the available VM options (ceph, zfs, lvm) to snapshot a VM, in order to get consistent backups, like the current pve backup does. Yes. > But how does that work with non-VM client? (some non-VM client systems run LVM, so lvm could be used to create a snapshot and backup that, for example. Does it do that? Will my non-VM mysql backups be consistent?) So here I do not have all details in mind but AFAIK: mot yet, it detects some file changes where inconsistencies could have happened but doesn't yet tries to detect if the underlying storage supports snapshots and uses that to get a more consistent state. For containers we do that explicit through the vzdump tooling. > > - Any timeframe for adding LTO tape support..?
