Shortage of disk space has become a problem that we (the systems
group) can't ignore any longer.  So here's what we're doing: When you log in,
your disk usage will be checked against your quota, and if what's left is 20%
or less, you will be notified.  You will also be notified if the disk has 10%
or less of its available room.  You may be well under your quota and still run
out of room if everyone else has filled up the disk. So, if it looks like disk
space might be a problem soon, you will be notified when you log in.  It is up
to you to determine if the available space is adequate for your needs or not. 

	Now, this has all been said before, except for the courtesy of warning
you to look out for the low ceiling.  Also, all those new disk drives have
lengthened (greatly) the time required for backups.  Every other weekend, we
make a tape copy of everything on all the computers, and put it in a fireproof
safe.  Or try.  It has started not to fit. 

	So, in order to A) reduce the tape storage requirements, B) reduce the
time spent for backups, and C) reduce the number of incidents where available
disk space falls to zero: 

		WE ARE DELETING ALL YOUR FILES
		   === ======== 

 	... at least all of them that are out of date.  BEFORE (yes, BEFORE)
the biweekly backups are done, we will automatically do a PURGE of all files
on all disks, retaining only the TWO (2) versions that are the most recent. We
have come up with exactly one instance where this would be inconvenient, and
we are willing to forgo the loss of information in that case.  The reason we
chose two versions is simple: one is not enough, and three is too many. 

	Note that this is scheduled to occur only on weekends.  The first
weekend that we will automatically purge will be about February 21st.  This
gives you about three and a half weeks to see if the files you have superceded
have any remaining value to you.  Note also that it will be done BEFORE the
backup, so the old versions will be gone.  The files will still be maintained
on the daily backups, but they have a short retention period.  You have been
warned. 

	Notice that this only applies to files that have already been 
superceded two or more times.  We don't expect any problems, but it's only 
fair to let you know.  You may, if you wish, address complaints to this mail 
address (KIM::SUTTLES), and I will ignore them at my earliest opportunity, 
unless you want to learn how to do backups, all day, every other Saturday.
