Question : How to span a large gzip file over many DVDs

I am going to use g4u (ghost for you) and it backs up via ftp to a large gzip file on the target computer.   I want to offload the large file to multiple dvd images for later restore to the target server.  I want to be sure this is done in a usable manner.  The split command has given me problems in the past and I would like to find a little more "softwareish" solution.

'split --bytes=nnnnn' should work fine, provided your copy of split is large file capable. To prove the result would be usable you could compute an md5sum on the simage file, split that into DVD sized files, then recombine those into a g4u image file and compute an md5sum on the result. If it matches the original sum the split/re-combine worked.
