Dear Misc@,
First up this is off-topic but I'm sure that someone here has experienced this problem in the past, so please forgive my asking as I'm not sure where else to turn.
I've got an OpenBSD fileserver full of files which I have built up over the years: Digital photos, 3D modelling files, company accounts, MP3s etc - roughly 30GB of stuff. The *really* critical stuff goes onto a weekly DAT tape and sent offsite. However, I want to back all of this data up on a regular basis (once every month or so) onto optical media and ship the discs offsite for safekeeping. Currently I am manually working out the optimum split of files over discs to use the least amount of DVDs possible - It is highly labour-intensive and I now want to be able to cycle my discs GF-F-S.
What I'd like to know is if there is a utility which will figure out the best way to portion out these files to save on DVD+RWs (i.e. which selection of files best utilise the 4.4GB available per disc). Ideally such a tool would give me appropriate output to shove into mkisofs and generate the images for burning (I'll then grab a directory listing into a text file which I can grep so I can find stuff later! =) I'd rather not tar and split the files as I am worried about corruption and recovery failure issues.
Apologies again for the OT nature of this mail. Any ideas very much appreciated. Warmest regards,
