We are in the planning phase for TSM 3.7 from ADSM 3.1.2.40.

I've read that DIRMc in the client options will no longer give us any
benefits because the directory information is retrieved from the database
during the restore process.

Can anyone tell me how this works?  Are directories backed up again after 3.7
implementation and stored in the data base? Would the data base need to be
increased because of this before TSM 3.7 is installed?
