I have an Acronis Backup for Linux Server 11.5 Software (Trial Version) and Backup and Recover the whole System as ist is. When needed Incremental. Restore over a created BootMedia CDROM.iso : Also install these USB Backup plugin, rsnapshot and Clonzilla etc. But not play enough with it...
@subzero79, i also tried the btrfs setup on kourim.net in a vm but failed... .Damn Could you write a little description about how to setup a system with boot from a subvolume or create snapshots and make backup from these snapshots and how to recover them back on the same disk or new one. Especially the OMV System HDD
