Do the manufacturers deliberately make their products perform poorly so that later one would have to waste time looking for the latest firmware?

OK - here is what I have. IIRC, the priority setting and the tape drive firmware were the 2 biggest things. I would do all of these though. Obviously, the drivers are firmware will depend on your tape drive. We have SDLT drives. Modifications made: 1. Placed each Adaptec LP160 SCSI card on a different PCI Bus. One SCSI card is now on PCI Bus 2 and the other SCSI card is on PCI Bus 7 2. Downloaded and installed latest drivers from Adaptec's web site for the 29160LP SCSI card. Driver version is now 6.1.530.201 dated 5/14/2002 3. Updated firmware on Tape Drives from version 4.1 to version 5.5. Obtained the firmware from Quantum's website. 4. Rebooted server and entered SCSI Bios by pressing <Ctrl> A at the appropriate time. Modified the settings of each SCSI card so that write-back cache was enabled on all channels. 5. Changed the priority of each Backup Job in BackupExec from Medium Priority to Highest Priority. As a result of these changes, we have seen an increase in throughput from approx. 130MB/min to over 600MB/min on each job, with both jobs running concurrently.

Subject: RE: Not using BLB, But getting really slow backups. Hang on - this is tape drive settings. Give me a few to find the stuff we used, and I'll post. We were getting really slow results as well. We are now well over 500-600mb/min for File, and 700-800mb/min for Exchange.

Subject: Not using BLB, But getting really slow backups. Hello, Veritas 9 - were using version 8 and getting the same problem. Exchange 5.5, NT4 SP6a We can not seem to get better then 100 MB / minute backing up the Exchange servers. using the Exchange agent. Many nights lately it is much worse. The NICs and ports on the switch have all be set to 100/full. IS Maintenance is from 4am - 7am. Ensured that Trend Server Protect is not doing any scheduled scans and that realtime scans exclude Exchange directories. The databases on the 2 servers are not big: One is 25 GBs with 7 GBs of whitespace The other is 17 GBs and only a 300 MBs of whitespace. Nightly oneline defrags are successful. Veritas tech notes point to a fragmented database - I don't buy that unless Exchange IS maintenance is not functioning on both servers. I also have a few other admins that swear by offline defrags - because they always seemed to help. Any ideas where I should be looking?
