I have some issues/questions with this suggestion ! Can I assume you really ment something more reasonable like 500MB not 5GB, since our mailbox limits are usually under 300MB ! ?
I still don't/won't have enough disk space to handle something like this ! The backup stream would overrun the disk landing-zone (200GB) way before it has a chance to dump it to tape ! Currently, the weekend/weekly (don't ask) full-backups of Domino systems is over 400GB (scattered across 5-Domino servers), spread across Saturday/Sunday to now overwhelm the 300GB landing zone storage pool. Very soon now, we are going to design/implement new Domino servers to handle over 40K individual accounts (primarily using IMAP/POP/Web) so the individual mailboxes won't get that large. But total backups over the week/weekend will be in the hundreds of gigabytes. Currently, the old mail system that is being replaced, is over 1TB of mail storage across 2-systems.

Not necessarily. You will have a number of small files (mailboxes, etc.) >I would also need to rotate/vary the DSM.OPT file being used >for regular backups versus big-to-LTO backups. Again, not necessarily. Set up a new disk storage pool with a NEXTSTGPOOL definition of your primary tape pool. Create a new domain and define all Domino nodes to belong to that domain; set the copy destination of the copygroup of the default management class of the new domain to the new disk pool. (Conversely, you can create a non-default management class within the existing domain, and use the Domino dsm.opt file to backup Domino files using the new management class's rules.) Set the max filesize of the new disk pool to, say, 5GB. All files that are larger than 5GB will automatically go to the primary tape pool. So, when the Domino node(s) backs up, all files < 5GB will go to the new disk pool; all files > 5GB will go to the primary tape pool. -- Mark Stapleton
