Actually, you'll *ONLY* be able to do so. I don't think that it'll
be possible to backup /dev/hda. Instead, you'll have to image all
the partitions (in old style partitioning) or all the logical volumes.

Partimage also supports NTFS, BTW. It's labeled as "experimental", but
this that it might not be able to image every NTFS partition. But if
it created an image, then that image will be good.

IMO no need for some cheapo closed source junk ;) OS rules! *G*
