what i want:
-backup my partition /dev/hda1 to a separate volume , into an image
(like /extern/image.img where /dev/hdc2 is mounted to /extern )
-what i have:
1 root partition /dev/hda1 with 6 GB
2 data partitions in /dev/hdc with 15 GB each
-what i did:
boot from knoppix-cd ( gives me a cd-based , ram disk-linux so i can
access my usual root system without interference)
dd if=/dev/hda1 of=/extern/image.img
-what i got:
a 2GB image file and an error about the size (like file too big) <--
this might not be the literal error message but its close enough.
so, after reading man dd and some websites apropos dd,
and not finding anything,
is there a known limitation to the size of files dd can handle?
any parameter that zips the image (making it smaller, since the
original / has about 66% vacancies )?
any other way of backing up a bootable partition so all files and
links are preserved and ready when i blow it back on?
i could use drive image (hang in extra hd with w2k) but would like to
use linux solution if possible.
