I use Keyworks.  Although keyworks is a TSR, it only becomes a TSR when it
loads and it removes itself from memory when it quits.  I am using an ancient
Mountain Tape drive with streamer tapes to backup.  Part of the Mountain Tape
software contains a file called autoset.  It takes the data for what day and
time to run whatever command line you add to the autorun.dat file.  My command
lines all happen to be keyworks commands.  I have one that deletes a group
of temporary files (that don't auto delete) just prior to the complete backup
each week.

From within my keyworks file I log in as user "backup" and then issue the
command that runs the tape drive to backup all of my data files.  My backup
runs at 2am.  I do an incremental backup on Monday, Wednesday, Thursday, and
Friday mornings.  I do a complete backup of the volume on Tuesday.

By the way, my user backup does not have supervisor privileges.  Backup is
simply mapped so that M: goes to SYS: and N: goes to SYS1: (which is my
data volume).  Backup has (and this is in NetWare 386, but I did it the
same way in 286) Read, Write, Create, Erase, Modify, File Scan, and Access
Control rights in M: and N:.  This is everything except Supervisory
rights.  I know that names are different in 286, but the meanings are similar.

I am currently looking for a better tape system, probably an exabyte drive, so
that my complete backup can run at night without the need to swap tapes.

I hope this helps.
