Do the numbers of objects saved change significantly ? My experience is
that fewer, larger objects will always save and restore relatively faster
than the same storage size when there are more objects. I understand this
to be caused by the objects etc information that is saved to tape as
distinct from just "streaming data".

I guess you have knocked out the obvious things like saving changed objects
which versus full saves ?

Are there any patterns to the changes that marry up with weekly or whatever
procedures ? I once had a save that did weird things the Monday after month
end. It turned out a couple of guys were running queries and then deleting
the output once they had run some summary queries over the rather large
summary files they created.

Is the start time consistent each night on the first save ?

I seem to recall that you use BRMS: is there some BRMS maintenance that
might makes a difference for example databases getting cleared down ? Do
you use Tivoli as well ?

Hope this helps

We do not do any save-while-active.  We bring down all Domino servers
prior to the backup.  Yes, we get growth.  Actually about a gig a day.
However, the growth is consistent, but the backup times do not seem to be
inline with the growth.  For example on a Tuesday it might take less time
than on a Monday, even though Tuesday had more information.

We have a program which adds up the size of all of our IFS root
directories, compares it to the previous day, and lists both the days, and
the growth.
