Symantec Backup Exec 11d compression

I am running Symantec Backup Exec 11d. The tape drive is a Dell PowerVault 120T using DLT IV tapes. In running a backup a of data that was a SQL database and mostly jpg's, it stopped at 40GB and would not go to the 80. I used the option for use Hardware compression if available else use software. Are there any other settings I need to select for getting the data to compress?
Thanks.

In the BE Software select Devices
Right click on the tape drive device
Click on properties
Make sure enable compression is checked
Make sure NONE of the boxes at the the bottom are checked.

If that does not work, try Hardware Compression or Software Compression when you create the backup.

Just looked, and it is checked already.

Is:

Block 32k
Buffer 32k
Buffer count 10k
High water count 7k

The next four boxes UNchecked?

I had this same problem in the past. I do not know why this particular configuration solved it, but it did.

Mine is:
Enable compression - checked
Block: 32k
Buffer: 32
Buffer count: 10
High water count? is 0
Read single block mode - unchecked
write - checked
Read SCSI pass-through mode unchecked
Write scsi pass-through checked.

Try unchecking Write and Write scsi pass thru.
run a small backup and see if you get compression...

i.e. on the drive the files = 2 gb on the tape maybe 1 -1.7 gb

Tried that. It is compressing fiiles some, but it's still not going to the full 80gb of tape.
