If, as part of a disaster recovery system, you wanted to make a copy of your openSUSE OS disk, what are the best programs to use? I guess as part of this there is the discussion of what might need to be changed if the image is on another disk (/etc/fstab) for example).
How about rescuezilla?
Or clonezilla. I don't have experience with any of them. I use plain dd (or dd*rescue), or rsync. Notice: if btrfs is on the root system, I can not handle it. I don't know how. For backups, I prepare laptops with an external boot disk; it contains a complete openSUSE system, plus a big data partition, encrypted, and using compressed btrfs. In it, there is a dd compressed image of the boot and system partittions, the table of partition data, and rsync of all, with a script of mine to do it. If the laptop contains windows, then a dd image of it all. The external disk has double the size of the internal disk, but in rotating rust. Not trivial to use, but not hard. -- Cheers / Saludos, Carlos E. R. (from openSUSE 15.5 (Laicolasse))
