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
