My knowledge is based on the Linux version. Both version should create compatible arcgives. Look at the manual: There are several options to increase compression ratio.

Ony my two cent -- your mileage may vary... Keep hacking! mcc PS: p/7zip is GPL'ed. Highest compression ratio for lowest price, hehehe :) Try using DBAN (dban.sourceforge.net) to cover the partition in zeroes before doing the Windows install; the repeated zeroes in the unused space will probably help reduce the compressed file size.

[gentoo-user] backup tool for my Windows 98 desktop?
Hello. Most of our computers in the Office runs Linux, however we have to keep a Win98 desktop (dual-boot with Linux) so that we can test several software. This is a purely testbed machine that need regular re-install. e.g. once a month, because it's placed publically and breaks frequently. I am tired of re-installing Windows 98, and then complete with other software (filezilla, 7-zip, extra editors..., OOO). I think perhaps it's easier after I re-installed everything I make a backup of the Windows partition onto a CDROM and later use that CDROM to restore the partition. The partition is 5GB but actual data on it is smaller then 600MB right after Win98 and complementary software installed. First I thought using gentoo live CD, use dd(1) to copy the partition to a file and burn it on the live CD. However the file must be too big to fit on CDR (en I think perhaps I can compress it), and yet how do I add it to the live CD iso image so that cdrecord(1) can burn it? I think perhaps I should first try borrow experience on gentoo user list. How do you think is the best approach? P.S. I know norton Ghost can do this but I don't think it's worth to buy a copy. -- gentoo-user@gentoo.org mailing list

To create an ISO image containing the file, you want mkisofs (included in cdrtools afaik): # mkdir win98 # mv win98.gz win98/ # mkisofs -o win98.iso win98/ From there, it's standard cdrecord procedure. To restore the partition later, simply boot to Linux and: # mount /mnt/cdrom # zcat /mnt/cdrom/win98.gz | dd of=/dev/(win98) If even gzip -9 can't get the partition small enough for you, I'm not sure what to do.
