    Default YaST's System Backup / System Restore

    Has anyone actually got YaST's "System Restore" to work, where it can read the archive(s) created by YaST "System Backup"? Out of several archives done by the SYSTEM BACKUP program, I think I was able to get the SYSTEM RESTORE to be able to read only one archive file, in openSUSE 12.3 KDE, and this problem occurred to me when I needed it the most. For openSUSE 13.1, the problem still remains (here); for experimental purposes, I did a SYSTEM BACKUP, then immediately attempted to restore it, but it could "not read the archive" and stated that it was probably not created by YaST's SYSTEM BACKUP.

    I am using it. It works fine. It doesn't restore everything perfectly, but almost 80-90% of settings are restored - even in OS-13.1

    Haven't tested this, but I would be very unhappy with an 80-90% result, horrifying. Backups need to be 100% reliable, a restore should be an exact replica of the original.

    But yast backup has never been an exact replica. I have not tried it recently. I tried it years ago
    and did not like it. Then it just saved changed files from the rpm database.

    I would have to try it again to see what it does now.

    I don't mean the filesystem, the tree or such, I mean an exact replica of what it was told to backup. F.e. extraction of a tar should give an exact replica of what was put in it.

    I think that it does.

    Hi all,

    I gave it a try - using the backup to store a restore tar archive on my NAS via NFS.

    It was a horrifying experience - I'm not quite sure what I did wrong (supposing that it was my mistake).
    I just created a profile for the backup and configured
    * the file name (eg. myserver.tar)
    * the target NFS server (e.g. mybox)
    * the target NFS directory (e.g. /targetvol/backup) - which is the NFS share I use to backup everything to (so there are a lot of directories and files lying there)
    chose "tar with tar-gzip subarchives" and configured it to create CD-sized archive files.

    Then I hit start
    and everything seemed to be fine - the backup did a lot of inspection of packages and built the list of changed files
    then it processed the archive and stored it on the NFS target.
    Then it stopped luckily - without errors.

    That something went terribly wrong was obvious some seconds later when a dolphin refresh on the NFS mount /targetvol/backup suddenly showed NO MORE FILES AT ALL.
    Everything was gone!
    Neither had the backup written any files to the NFS share (so no "myserver.tar") but also everything else that was located on that share has been deleted.
    I know that it had to be the interaction with the backup operation because I stored some files manually there (using rsync -av) , minutes before I tried the system backup. And back then everything was still ok. I still could see anything in dolphin (also the freshly rsynced files).

    Of course I immediately logged on to the NAS and inspected the file system "locally" not through the NFS export to see if something was left. But it was empty - completely.

    I still suppose that I did something wrong - but at least it seems that this is an easy mistake to do (no warning anywhere that there be dragons).
    So I am kind of cured of this backup solution. For me it has done the exact opposite of backup...

    Had anybody else experienced the same?
    BTW: I'm using a Synology NAS with NFS v3 shares (I guess the NAS does not support NFS v4) together with SuSE 13.1.

    still somewhat shocked greetings
    bjo

    Never.
    No idea why such a thing would happen.
