Backup with Mondo Rescue Disaster Recovery Tool is not a problem but restore will NEVER work right?. "UUID" keys for HD, fstab, linux partition etc. Are these randomly generated on linux system? so if you restore a backup with mondo it will never work because UUID keys will be random re-genreated during boot.

I don't remember exactly how Mondo worked, but: UUIDs are created when formatting a partition (mkfs.*) If the clone is done as an image of the old system, it will work. If the clone is a copy of the contents, ie, the files of the old system, it will not work. This is something that should be documented at the mondo site. - -- Cheers, Carlos E. R.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, verwijs, i don't know this tool, i make dd (or dd rescue) backups of whole hdd's / partitions. it need this here to work after restoring: posibility 1: (may have also his disadvantage) (used for ext3/4 and reiserfs without gpt) (with new, same size or bigger size hardrive at same mainboard) always install your opensuse in beginning of installation process by hardrive experts options, and select there by default link with "drive name" fstab looks like this (only example): /dev/nvme0n1p1 ext4 noatime,acl,user_xattr 1 1 or /dev/hda2 / reiserfs acl,user_xattr 1 1 posibility 2: if standart opensuse installation (using id / uuid?) and fstab look like this: /dev/disk/by-id/ata-ST31000524NS_9WK4DF3V-part2 / ext4 acl,user_xattr 1 1 (i am not shure if this describtion here will still work with verry new opensuse versions - its about 2 years in past i have had last time writing back a backup): the haddrive who has to be backuped (before you have a problem): ll /dev/disk/by-id/ > to-a-safe-place.txt (or if installed with option uuid ll /dev/disk/by-uuid > to-a-safe-place.txt) after you have installed your backup: boot with a live cd (as example systemrescue-cd) ll /dev/disk/by-id/ > to-compare-with-above.txt check and change all positions where the old names are in: (this list maybe not complete, so please search the files with the searchstring's from to-a-safe-palce.txt) /boot/grub device.map /boot grub menue.lst /etc/sysconfig/bootloader /etc/fstab if you backuped your boot drive you have to change also inside the initramdisk maybe here: /boot/initrd symlinked to /boot/initrd-3.0.101-102-desktop copy it to empty directory and unpack ist: gunzip -c initrd-3.0.101-102-desktop | cpio -i delete the old initrd inside this directory. search as described above and change all: ./run_all.sh ./config/mount.sh ./config/storage.sh rename or delete the old initrd inside /boot pack all topgether with find . | cpio -H newc -o | gzip -9 > /boot/initrd-3.0.101-102-desktop now system should ;-))) start again. there maybe easier ways to do this: (i used to run "real opensuse computer with only one harddrive" inside virtual machine - after throwing away verry old hardware) copy your whole harddrive to a image, start a kvm with this image, it will not start, but asked you some questions, say always "n" you will get a prompt. then cd /dev/disk/by-id mv "the existing names" "correct-names" exit should boot for only now. now inside the files /etc/fstab und /boot/grub/menu.1st chaninge names mkdinitrd (some warings appear) after another start: inside /boot/grub/device.map also changed names mkinitrd now starting without problems. simoN ps: make a file backup for userdata-files in addition my also be useful.....
