The error just means that whatever size you formatted your archive for, that the archive is too big for that size and will need to make multiple files.
So lets say that you archive format was for 4 gig segments. If you do a size est. and it says 16 gigs. Then when you archive, you will get this "error"- but it really just s means that the file archive will be 4 x 4gig files with a main header file.
