Wanted: advice on backup software

[Matthew Lewis]

Hello!  I would like to use one tape for multiple incremental (or full)
backups for several relatively small file systems.  I need to be able to
retrieve earlier versions on the same tape, if necessary.  What is there
tat does this?  I know that you can DUMP to a tape more than once, if you
skip past the previous records, but this rules out doing the backups
automatically.

Thanks in advance.  Mail replies will be summarized.
