Here's what I do:
Using Drive Image 4.0 to backup/restore ext3 partitions
To backup an ext3 partition:
1.remove the journal by executing the command
tune2fs -O ^has_journal /dev/hdxyz
from a Linux system other than the one you are backing up.
2. create the backup image with Drive Image 4.0
1. restore the backup image with Drive Image 4.0
2. replace the journal by executing the command
tune2fs -j /dev/hdxyz
from a Linux system other than the one you are restoring.
*** WARNING ***
If the partition you are restoring is a root partition, always check
its /etc/fstab and make sure that all partitions it references by means
of LABEL= still have the same e2labels that they had at the time the
partition was backed up.
Basically, that's all there is to it:
remove journal -> create backup image
restore backup image -> replace journal
p.s. If you want to use Partition Magic 7.0 to /delete/
an ext3 patition, you also have to remove the journal first.
