I wanna have your advice.
I have many partitions on my laptop with several linux install.
I want to rearrange all partitions, to better use space.
Basically 1 primary for datas (ext4), 1 primary for windows, 1 extended to store all linux paritions.
(I still have this 1st partition used by windows rescue or something like that and I cant merge it into another one ...)
What is the best way to backup/restore those linux partitions ?
My idea was to
1 - backup all distro to ext storage using tar (I do not backup OS will runnning this OS) :
=> mount /dev/sdaX /mnt ; cd /mnt ; tar cf /data/thisdistro.tar . ; cd / ; umount /mnt
2 - boot external device (like usb key), rebuild parts, restore all distros, change back fstab with new partitions
3 - On the last restore (sabayon) rebuild boot block (grub-install/mkconfig)
My main concern is using tar, is that the proper backup tool.
Any comment ?
