Hi All,

Im facing a similar issue. We have LTO2 tapes which has native capacity of 200 
GB and compressed capacity of 400 GB.
Did the following tests to check which compression can help in our environment.

Actual data size 250 GB
With software compression enabled, data written on tape is 99 GB
With hardware compression enabled , data written on tape is 250 GB

So, should i conclude that h/w compression is not useful or is there something 
wrong with the drive.

Regards,
Backupadmin
