We addeed MEMORYEFFECIENTBACKUP YES to the DSM.OPT file, but I don't know how 
far up/down it processes for a directory in that mode.

I'm thinking of just -INCRBYDATE. This is an imaging server where documents are 
scanned and stored here. Don't need to worry about deletions. It will still 
take a while to scan a filesystem of 15+million objects, but this way I don't 
have to worry about the overhead of sync'ing with the TSM server for each file 
backed up.

Can't go 64-bit due to the application.

Thanks,
Bill
