Yes, I will also try to make a copy with DD to an iso file but I'm not sure if it is sufficient. For example If I clone the samsung recovery partition and later restore it, how should it be restored? Same place on the drive? How does the F4 recovery option at boot will find back the partition (by its name or position?)
Also not sure it the recovery partition is enough to restore the raid on the disk and other partitioning...
Anyone else a suggestion?
will clone the drive sda to another drive of at least the same size.
sudo dd if=/dev/sda of=/dev/sdx bs=4096
will make a compressed image of the drive sda. During the these dd operations, partitions of the drives should not be mounted.
sudo dd if=/dev/sda bs=4096 | gzip > dd-sda.gz
