Del, What folks do not understand about TDP for Exchange is that it is just a vehicle to store and manage exchange backkup objects. There are 3 types, full, incremental, differential. Full backs up everything including the recovery logs. Incremental backups what has changed since the last full or incremental. Incrementals have to be restore in total one at a time on top of the FULL to get back to where the failure is on time. Differential is all the changes since the last FULL every time you run it. Nothing is done with the logs on differential or incremental based on what I know, only on FULL are they backed up/deleted.
I think I am right on this. The key is that Exchange just provides an intelligent object name and pours the data to TSM in that object. Think of it as a container. By having intelligent names the TDP can figure out what has to be done to restore the Exchange store. I think a clear explanation of how these TDPs generally work would really help many people on the list. MS-SQL is similar. But Oracle RMAN keeps the intelligence in its own RMAN catalog. SAP is similar to Oracle except the backup information (BKI) file is required to restore the database not the RMAN catalog. These are the ones I have researched and studied a little bit. Paul D.

Wolfgang, No, because the command to run a FULL backup is different than the command to run an INCREMENTAL backup. Thanks, Del
