Use “dump” and “restore” to create file system images. “Dump” and “restore” are provided by modern, production stable file systems. For example XFS:

Or even better, use a virtual machine (which is hardware independent):

[CODE]Boot from SLED Installation-DVD. Press button . Choose “More” => „Rescue System“
Login „root“

mkdir /usr/lib/microcode/root

mkdir /usr/lib/microcode/home

mkdir /usr/lib/microcode/backup

mount /dev/sda1 /usr/lib/microcode/root

umount /dev/sda1

mount /dev/sda5 /usr/lib/microcode/home

umount /dev/sda5

mount /dev/sdb1 /usr/lib/microcode/backup

umount /dev/sdb1

mount

df -h

xfs_repair /dev/sda1

xfs_repair /dev/sda5

xfs_repair /dev/sdb1

mount -r /dev/sda1 /usr/lib/microcode/root

mount -r /dev/sda5 /usr/lib/microcode/home

mount /dev/sdb1 /usr/lib/microcode/backup

mount

df -h

Full Backup

xfsdump -l 0 -f /usr/lib/microcode/backup/Linux/ /dev/sda1

xfsdump -l 0 -f /usr/lib/microcode/backup/Linux/ /dev/sda5

df -h

umount /dev/sdb1

umount /dev/sda1

umount /dev/sda5

mount

poweroff

Remarque: „-l“ => small “L” like „Level“.[/CODE]

[CODE]Complete restore
=> Preparation (boot SLED12 installation dvd ans so on)

mount /dev/sdb1 /usr/lib/microcode/backup

umount /dev/sdb1

mount

df -h

xfs_repair /dev/sdb1

mount -r /dev/sdb1 /usr/lib/microcode/backup

umount /dev/sda1

umount /dev/sda5

mkfs.xfs -m crc=1 -fL root /dev/sda1

mkfs.xfs -m crc=1 -fL home /dev/sda5

mount /dev/sda1 /usr/lib/microcode/root

umount /dev/sda1

mount /dev/sda5 /usr/lib/microcode/home

umount /dev/sda5

mount

df -h

xfs_repair /dev/sda1

xfs_repair /dev/sda5

mount /dev/sda1 /usr/lib/microcode/root

mount /dev/sda5 /usr/lib/microcode/home

xfsrestore -f /usr/lib/microcode/root

xfsrestore -f /usr/lib/microcode/home

df -h

ls -alh /usr/lib/microcode/root

ls -alh /usr/lib/microcode/home

For SSD only:

fstrim -v /usr/lib/microcode/root

fstrim -v /usr/lib/microcode/home[/CODE]

mount -o discard /dev/sda1 /usr/lib/microcode/root

mount --bind /dev /usr/lib/microcode/root/dev/

mount --bind /proc /usr/lib/microcode/root/proc/
