Not exactly, but I do have a program that sits in front of tar and feeds it
filenames, interacting with an operator to swap tapes when it thinks the
tape is almost full. Its main purpose is to keep tar from ever reaching
EOT. A side benefit is that it can do incremental backups as well. Let me
know if you're interested, or I'll post the thing again if I get enough
requests.
