UNIX Desktop Questions & Answers

I've been handed the task of backing up some of our system files on a Solaris box. No probs. Zipped the logs that needed backing up but my superiors do not want it on tape, they want it spanned on CD's. The CD-Writer is available on a MS box. FTP'd the zipped logs across too the MS Machine but now i need too span this 20+ GB of data onto CD.
Problem 1. How too span this over multiple CD'z. ( Does winzip support this ? )
Problem 2. Easiest method too rebuild.

If anyone knows a better way too go about this it would be much appreciated. I know this is not a purely unix post but i'm taking a chance as i have too have this done asap.

I see this post is old , i hope you have solved it by now, but in case jfyi

1) use split to chop your files before ftp (binary)
2) be aware of problems using a windows filesystem with unix backups, you may need to use dos2unix to correct problems if your zipped files seem corrupted.
3) Obviously ftping 20Mb of data isn't the best scenario, im sure you can get a CD writer on the local machine somehow and use tar.
