Hi,
Is it possible to use K3B to back up data that is over 700MB in size so that it spans multiple backup CDs? I remember zip used to be able to span backups across multiple floppy disks.
Thanks
Clive

I don't know: I don't use K3B.
I do use mkzftree to make a compressed tree of files and then mkisofs to create an ISO image. Typically, that gets well over 700 Mb to a CD which is directly readable on Linux but not other systems (they need to manually decompress the files), but only postpones the problem.
DVDs are a good alternative to CDs: bigger and (according to the specs on the side of my box) four times as fast. They (and the media) are cheap, maybe for your volumes of data cheaper than CD, but again, they only postpone the problem.
DAR (see sf.net) can create multivolume archives. So can mondo, but the code's still pretty terrible and I have doubts about its safety if there are "bad" filenames around.
I quite like external USB2 drives: I can back up my whole 80 Gb drive in my laptop at 14 Mbyte/sec. Tarballs, ISO images or whatever of ones valuables on an external laptop drive has to be pretty convenient, or you can go for the largest ATA drive you can find and put that in an enclosure.

Umm, PKZIP can do that. If that's what you really want, then you can try running DOSBOX or DOSEMU.
Another possibility is zip + zipsplit.

Come to think of it, tar an other archive utilities can do it: you need to specify the size of the "tape volume" and maybe use a script to do stuff with the files it creates it.
It doesn't (or didn't when I looked years ago) hand compressed output well as the size you provide relates to input sizes.
afio (not a standard component) is better as it can create compresses archives sized on the output size.

Mondorescue is a great tool for doing backups of specified size (CD, DVD, Tape, etc.).
http://mondorescue.berlios.de/ is the current site for downloads. http://www.mondorescue.org/ was the original site and has some information on it.

Also, in a crunch, use mke2fs and specify the filesystem size to be a CD or a DVD (or a 40GB DAT, etc etc...)
Plenty of backup options under Linux...
Historically you only need to backup /etc /home and related -- backing up the whole filesystem daily or weekly is not recommended. The only time I make a complete partition backup is immediately after system build to blue print the installed drive and I use BING (http://www.terabyteunlimited.com/) for that.

Too many, IMO, and none of them quite adequate for all use.

Hmm. I include /usr/opt, /usr/local and /var (at least parts of /var, anyway).
