Hi. I'm trying to backup our lan /home directory (20 boxes, 1 NIS server, all 9.1) to dvd. I can tar and gzip it from 6.4Gb to 4.4Gb. Today. Tomorrow a smaller /home may crush down to greater than the magical 4.7Gb. Is there a way to estimate the final .tar.gz size without having to wait the hours it takes to actually do it? Or WHY. I can't always be there to change media and the lan has to be quiet. Cheers, Steve.

I would recommend you take a look at Denis Corbin's 'dar' (Disk ARchiver, http://dar.linux.free.fr/). It's a tool which can slice your backups into chunks which fit nicely on your backup disks. It has many interesting features, so have a look. If you are using the KDE desktop, you might also look at KDar, which is a graphical frontend to the dar command tool (http://kdar.sourceforge.net/).
Cheers, Steve.
