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.

Rob,

Two thoughts come to mind which you didn't mention:

Have you ruled out that the backup may be performing well but that there
is significantly more stuff in your Domino IFS directories on some
nights?

If you have a Domino server active during your backup, have you checked
the Domino logs to determine whether some scheduled tasks kick in during
your backup?  My recollection is that some of the rebuilds can be rather
intense and could be the source of your CPU spikes.  The iSeries history
log would not necessarily show job initiations because the tasks would
be active all the time.
