hmmm...

i have only set COMPRESSION=ON in the Option Set and the client dsm.opt
file.

whats the different in "compression always" and "compression=on" ?

another question:

we have a big disk pool, so i must compress the data, the diskcopy pool is a
adic faststore 4000
library, i think the library also tries to compress the data once more..

does a DLT drive check that the data is already compressed and dont compress
it once more,
or are the files getting bigger when the drive writes it to tape?


best regards
