I was just thinking this through too, as I want to migrate my system to a
bigger disk.
Yes, I know there is a howto, and yes, I know there is dd.
Thing is, dd, much like Norton Ghost on linux partitions, dumps the whole
damn thing. Ghost on FAT/NTFS FS's is smarter, making a filedump, and not
mirroring the empty space of the partition.
Question #1: Is there anything for linux that does this form of
filedump? The only thing that springs to mind is tar...
Which brings me to Question 2:
.. thinking that, tonight I ran tar and mirrored my 2
gig system partition (with roughly 1.5Gigs in use).
SubQuestion: anyone know why tar won't listen to the
"stay-in-local-filesystem" switch? It swallowed up my /boot partition,
where it's actually a totally different primary partition on the disk?
. Back to Question2: I got a 600Meg tar file when it was done. Is this
possible? (*bad stomach feeling*) could glueing the whole filesystem
together actually bring down the volume of your files to 40%? If you're
wondering what I have installed, it's an "Almost
Everything" installation of SuSE 7.
If someone could also point out some well-used GPL'd backup proggies, and
throw in a recommendation or two, that would also be nice.
Thx people.
