Hi all,
As far as I know ist there no need to dd the hole disk. It should fit if you So just:
- take the snap
- mount it
- pack it
Yep, but you'll not be able to restore it into a bootable system again if you only backup the files. You could however, take a backup with dd of the partitiontable+bootloader and then afterwards backup the files of each partition.
On a restore you would then copy back the partitiontable+bootloader, format the filesystems and copy the files back.
But comparing this hacky solution to just using qcow2 on top of a Linux filsystem, the qcow2 solution seems much nicer :) Especially now when the qcow2 performance has been highly optimized: http://fedoraproject.org/wiki/Features/KVM_qcow2_Performance https://rhn.redhat.com/errata/RHSA-2009-1659.html
