Backup questions

[jonv]

I am trying to back up my server on a regular basis, while then burning the backup files to a set of DVD R/W's. I have been using tar+gzip, but the file size is to large. I tried to use rar because it can break up the backup into 4.0G chunks but rar does not archive the owner/group information correctly. Does anybody know a way I can do this?

Thanks,
Jon

I use bzip2 for all my compression. It's very tight (compression-wise), but it's proc-intensive.

That's nice, but what I am trying to find out is a way to split the backup into 4G chunks so it can be burned onto DVD-R/W's. The compression method may help get the size down further but I still need a way to get the data on to multiple DVD's.

Thanks!

Reading the bzip2 manpage says to me that I don't think you can...:/
