one of our postmaster mailboxes (we have one for each of our 9 sites) was 23 gigs when I started here a year ago, no one had logged onto it in several years and it had over 6 million items in it. It took me 3 days to use exmerge to shrink it down. Our biggest user mailbox is about 3 gigs, with quite a few other mailboxes over 1 gig. Other than that we're pretty average (we have 8,000 users and 15,000 mailboxes). Our backups have improved dramatically at sites that upgraded their tape drives to SDLT320. At our largest site we backup 625 gigs a night (exchange mailstores only), it took 16 hours before we upgraded to SDLT320's and re-arranged our backup jobs, now it takes less than 5 hours. We're planning on buying exchange dedicated SAN's soon so we'll be moving to online snap backups of exchange, then streaming it off to tape, which will help a lot.
