Hardware compression does not work on Ultrium 3-SCSI tape drive.
Recently hardware compression quit working for weekly full backups. In the same time daily differential backups, much smaller in size, compressed just fine.
Before compression rate was between 1.7 - 2.5
Backup job size is about 450gb.
I am using BackupExec 12.5
Nothing changed on the system to trigger this.
Is there anything can be done to fix this?
Drive firmware version is D22W.

Perform the test with Library and Tape Tools, it will use hardware compression.

Re: Hardware compression does not work on Ultrium 3-SCSI tape drive.
Hardware compression is configured inside Backupexec software and in configuration for tapedrive driver.
Sure I have three option here: device, driver, software.
I am looking for your thoughts what could be the likely source of problem.

Hi,
I will check the Backup job settings for which the compression is not working. You have an opton to enable or disable Hardware compression for the pirticular job in Backup exec.

Raj

Re: Hardware compression does not work on Ultrium 3-SCSI tape drive.
I know this is a VERY old thread, but did you find a solution to this problem? I have a similar problem I've been unable to solve.
Thanks

Re: Hardware compression does not work on Ultrium 3-SCSI tape drive.
First I deleted backup job in Backupexec and created new one from scratch, including selection list. It improved average compression from 1:1 to 1:1.4. I also changed SCSI terminator, without any effect.
Year later when I started recycling old backup tapes I noticed that compression performance on old tapes, purchase in a first batch, is better than on newer purchased batch. Both of them obsolutely the same HP tapes with the same part number. On older taped I have compression of 1:1.6
Make you own conclusions.

Re: Hardware compression does not work on Ultrium 3-SCSI tape drive.
I ran HP Storage Works Library and Tape tools which confirmed that the drive was faulty.
HP then replaced the drive under warranty and backup now works.
