Hi Rick, The incremental backup in TSM is the best solution to optimise the database size, instead of doing daily selective. When you want to do the incremental backup in an seperate diskpool create a new management class will the appropriate backup attributes and specify the storage destionation to you new diskpool. Specify the list of files to backup in the dsm.sys file using the inclexcl option.
The option DIRMC is used to specify to which management class does the directories should be backuped, not the files. If you donot specify this option(DIRMC)directories will be automaically backuped by TSM to the Management class which has the higher retention in the activated policy set. Hope you understand ....

My company does mainly full/selective backups and does not use incrementals. I recently wished to change this policy to take advantage of TSM's ability to handle incrementals (besides our tsm DB is getting large). We do incremental backups of a flat file database to disk and those expire after a period of one day. This is a "just in case" backup. I wish to do incremental backups but to a different disk pool. I just read about an option that can be put in the dsm.sys file DIRMC. Would this be the option I need for placing my incrementals into a different management class (ie .. different disk pool)? I say yes but I would like confirmation. The other question that I have is that in planning for a DR do I just follow the old rule of incrementals daily and a weekly selective and if you have a disaster get the weekly and the incremental and restore. I know none of you know what are retention or backup policy's are but I want to know if this jives with the "normal" TSM procedure or if there is a better way that I am not aware of. The classes dont cover policy's very well and what is the best method so im relying on everyone's experience here. Thanks for the assistance all, Rick.
