Larry,

That depends on your backup startegy.  Notice that I am only deleting
database backups - not all volhist.  Basically, If I lose an adsm sevrer
and have to restore to a state more than seven days old you have bigger
problems.

Thanks,

Joel McCarty

Hi Joel:

Than there is no value to retaining volhist data?

Larry,

Here is a perl script that I use at my site to get rid of old db tapes.  We
do a db backup every day so the scripts deletes all but the last 7 days
backups.  Hope this helps

#! /usr/bin/perl

use Time::Local;

# Convert current date to epoch seconds - subract interval (1 week) then
convert
# back to normal date

$interval = 604800;
$currdate = timelocal($sec, $min, $hours, (localtime)[3,4,5]);
$prevdate = $currdate - $interval;
($seconds, $minutes, $hours, $day_of_month, $month, $year, $wday, $yday,
$isdst)
 = localtime($prevdate);
$year += 1900;
$month += 1;
$month = sprintf("%.2d",$month);
$day_of_month = sprintf("%.2d",$day_of_month);
$prevdate="$month/$day_of_month/$year";

system("dsmadmc  delete volh type=dbb todate=$prevdate > /tmp/rmvo
lhist");

system("mailx  -s dcadsm-volhist\@hertz.com -r jmccarty\@hertz.com <
/tmp/rmvolhist 1>/dev/null");

 Subject: Volhist deletions









Hi:
I recently had to delete all references to  ADSM database backups that were
backed up to a TYPE=FILE device class. Prior to deleting these entries,
ADSM would not allow the deletion of the device class.

While looking at the volhist entries I noticed they go back over a year. Is
there any purpose to keeping these entries, and is there a way to
automaticly trim the entries that are kept in the volhist file?
