You could use dd to just do a backup of the mbr/partition table (first
512 bytes)
dd if=/dev/sda of=backup_mbr.img bs=512 count=1
then writing it back is as simple as swapping the if= and of= values.
then just tar up the partitions.. In the past I've used tar with
permission preservation enabled (-p) for entire root partitions, and
they worked fine after unpacking them to an empty partition later on.
tar -czvf partition.tar.gz /dev/sda1
Just some ideas.
