Yup, good ol' file marks. That's what we're using here. We're putting file
marks on the exabyte tapes every 100M. To restore from the end of a tape,
we just forward space file a couple of file, and start the restore from there.
Restoring from the end of an exabyte tape takes about 20 minutes.
We're keeping a list of files dumped so we know in which section of the
tape they are.
But I'd be interested in knowing more about that "record number" scheme.
