So What you mean is TSM server don't has its own encryption instead help by the 
driver or client side encryption?
1) What i mean is that when data store inside the storage, any encryption step 
will run in this stage before it backup into a tape?

2) Will it possible a TSM server using both encryption such as driver 
encryption (AME, LME or SME) and client side encryption?

For example, when a client submit a data or info to the storage, the data was 
encrypted and stored in the storage. After that when backup is start, the data 
will encrypted second time and stored into a tape by the driver.
so does it make sense?
