The /mnt/local/etc/sysconfig should normally contain lots of files of the restored image. Was the restore successful? The kernel file is one of the many files you find under the /etc/sysconfig directory. At least at SLES

Hi, as you see in the log file, the disk was partitioned and formatted as well, I can even see that it was mounted as "/mnt/local" , but no restore was taken place before running "finalize/SUSE_LINUX/i386/17_rebuild_initramfs.sh". there is no error regarding backup image, it seems that there is something went wrong in between format and finalize. thanks a lot for the reply.

What is the content of the /etc/rear/local.conf file? And, what is the output of rear dump?

a417237 commented at 2014-06-25 14:28:¶

backup=netfs
netfs_url=file:///mnt/cdrom
netfs_mountcmd="mount -v -t iso9600 /dev/sr0"
netfs_umountcmd="umount"

@a417237 I cannot follow - I'm sure the system restore was not performed, but how did you make backup? And which variables did you define before running rear -v mkbackup? A rear dump would be really useful

@gdha , I did a backup using a usb disk "output=iso,"; rear format /dev/sdb; rear -v mkbackup;
it was done pretty good. then I made a dvd using the following procedure.

initrd.cgz , unpacked and edit the local.conf to netfs_mountcmd="mount -v -t iso9600 /dev/sr0"
2 new initrd.cgz was again copied to isolinux

the dvd is written on dvd media
booting is fine, menu selection works, automatic recovery lands in the "ERROR"

Ok, you want to backup on a DVD, perhaps you could try (and use the latest rear-1.16.1):

## ISO backup included
OUTPUT=ISO
BACKUP=NETFS
BACKUP_URL=iso://backup   # this could  be a mounted USB disk on /backup
OUTPUT_URL=nfs://SERVER/vol/linux_images_dr/rear  # location to copy ISO image to
ISO_MAX_SIZE=4400
TMPDIR=/mnt2/tmp  # alternative /tmp (as DVD size might be too big; use another location)

Thank you very much for the help. is there any document available to create a disaste recovery dvd using rear ?. my understading is that the software can be used with USB and NFS backup only.
