Thank you Ed. I would like to start doing DEL VOLHIST TYPE=ALL TODATE=-21
because no one has purged VOLHIST since the dawn of time here. (I inherited
*SM). I want to make sure that I do not lose any volume data. My
understanding of how it works is that all volume data is stored in the
database and the only time I will need VOLHIST is to pick up any volumes
created since the last database backup in the event I have to restore back
to that last backup. Those volumes would need to be audited. It is my belief
that I do NOT need to retain VOLHIST data older than my oldest DB backup. I
am just being extra cautious. Do you see any fault in my thinking?

+ Well, I suppose that everyone has their own way of doing
+ things, and without being critical of others here's how we
+ have it working.
+
+ 2 things run daily relative to volume history
+   "DELETE VOLHIST todate=today-16 type=DBBACKUP"
+   "DELETE VOLHIST todate=today-30 type=all"
+
+ Where using DRM set the following way ( from q drmstatus )
+     DB Backup Series Expiration Days: 15 Day(s)
+
+ I like to have a decent record of the volume history as we
+ have a 3494 library which was giving a lot of trouble with
+ volumes suddenly disappearing.  Now, the reason those volumes
+ were disappearing is that the "delete volhist type=backup"
+ was set to 7 days, which was before those volumes expired in DRM.
+
+ WHAT EVER YOU DECIDE MAKE SURE THAT WHEN YOU DELETE VOLHIST
+ FOR DBBACKUP TYPES THAT IT IS NOT SET TO A NUMBER LESS THAN
+ HOW DRM IS SET TO DELETE THE SAME ( if you're using DRM ).
+
+ As you can see perhaps, I got a little frustrated trying to
+ figure out why DRM was losing 4+ volumes daily.  I wish I had
+ subscribed to this list earlier.

+ Dear fellow *SMers,
+
+         I would like your input on something regarding the
+ delete of volume
+ history records. From reading this list for some time, I've seen many
+ different opinions on how it should be handled. I would like
+ to hear your
+ thoughts on how you are doing it and your reasons for doing
+ it that way.
+
+         Should only the DBBACKUPS be deleted after x amount of days or
+ should ALL records older than the oldest DB backup be
+ deleted? What are your
+ opinions on this?
+
+            Thank you,
+             Al
