Thanks Frank,

Now that I can trust mminfo -Xa over my excel calculations :) I'll check
if a single ssid is being reported multiple times.

Best Regards,

This is what you did in the past month, so it's fact that's what you
backed up in the past 
month.  Not what you will necessarily back up in the current or future
months.

You are assuming that you will back up 1TB every day for all 24 days of
your cycle.  Perhaps 
that's true -- perhaps that's not true, it's a number based on an
assumed amount of data, not 
on any facts.

Any AFTD's or other reasons for a single ssid to be reported multiple
times?

For what you did in the past month, it's 22TB.  For what you think you
will do this month, it's 
24TB.  The 32TB is an accounting error :-)
