Hi
Standard F12 dump/restore has some problems which have been solved
in latest CVS
http://sourceforge.net/tracker/?func=detail&aid=2964667&group_id=1306&atid=101306
This now works successfully at about 1GB/minute on my machine
dump 0f - /dev/sda7 | (cd /mnt/out; restore -rf -)
---------------------------------
I have also found fsarchiver to be very useful
Neither source nor destination are mounted in this example
Simple ext3 root partition source reinstalled on ext4 partition
The compressed root partition is 5.7GB when df shows about 15GB
13mins for save and 13min restore to same physical disk
fsarchiver -o -j4 -z 6 savefs /tmp/fsarchive_sda7.fsa /dev/sda7
fsarchiver restfs /tmp/fsarchive_sda7.fsa id=0,dest=/dev/sda2,mkfs=ext4
Edit /etc/fstab, /boot/grub2/grub.cfg ... (in this case for ext4)
