No compression on Dell PV-100T DDS4 drive

Hello -

I have a Dell PV-100T DDS4 20/40 tape drive and Veritas Backup Exec 9.1 for Small Business Server Premium. The OS is SBS 2003 Premium with current service packs and updates. I back up a combination of Exchange and SQL databases, System State, and user documents. Hardware compression is enabled on the tape drive. The drive firmware and the Veritas drivers are current. No matter what type of compression is enabled in the Veritas software (Hardware otherwise software, Software) all I get is a 1:1 compression ratio on the tapes.

Any ideas?

Thanks!!!

Steve B.

Are you using compatible media.  I would check the Veritas website to check this.

Try disabling the hardware compression on the drive, and run software compression only.  
(The hardware compression may not be supported properly, and while on is preventing the software compression from running.)
The software compression should be internal to the software.  
You did not mention how much RAM you have.  You might check the required and recommended amount of RAM for your equipment, OS, and configuration.  If there is not enough RAM to run the software compresssion, it also might ignore your request for compression.

Do the following:
Enter the Backup process properies and go to the 'Setting' section => At the 'General' tab you have an option "Compression Type" => Choose: "Hardware (if available, otherwise software)" => 'Submit'...

This is it.

PS

You may take in-mind that data is not always compressable...

Thanks to all for your halp on this. I think that this is a Veritas software issue. When I run the backup and let it fill the tape I get about 25 GB, or 25% compression. The Veritas software is not reporting any compression. Thanks to all!!
