Copying tape-to-tape on UNIX
I am using a 4mm tape to backup my Unix system. However, I wanted to make a copy all of the files and archive headers (or just the archive headers if that's possible) created on one of my tapes to another 4mm tape. I only have one tape drive. Is there a command that will complete such task? Thank you. Smilie

What commands are you using to create these tapes in the first place?
