I have a giant file (>20 gigs) sitting on my source machine and I need to transfer it to my target machine. For the purposes of this question, let's assume that I do not have network connectivity between the two machines.

I need to break this file into a series of smaller files, write the smaller files to DVD(s), then re-assemble everything on the target machine.

Both source and destination machines are Linux boxes. Is there a way to accomplish this using tar? I have a feeling that I need to use the --multi-volume parameter. What are my options?

I need to be able to specify the size of the volume files, in order to make sure that each one will fit onto a single DVD.

Thanks!
