Backup time has tripled

[MrBean17]

Hello all,

On 4/7/04, our backup for 49.3gb took 5 hours and 36 mins.
Last night, our backup for 51.6gb took 14 hours and 20 mins.

Granted, more data = longer time to backup. But still, 2+gb adding another almost 10 hours just does not seem right. Consistently since 4/7, time has been slowly but surely increasing in time.

Windows 2000 Server (SP4)
Dell PowerEdge 2500
Dell PowerVault 110T (DLT1 Tape Drive)

Dell PERC 3/DI Raid
- Driver 2.7.1.4944

Veritas Backup Exec
- Version 8.50 Rev. 3572

I know the following does need to be updated :
System BIOS
ESM Firmware
Perc driver
Perc Firmware
Management Software

But, I do not understand why the backups have increased so much as of late.

Any suggestions would be greatly appreciated.

SCSI - Adapter AIC-7899 Ultra 160/m

Be sure to use the Adaptec drivers for the Ultra 160 Controller. Microsoft or Veritas drivers just don't seem to cut it, at least on the IBM's I install them on...

MS or Veritas = 400Mbpm
Adaptec = 1.5 - 2.0 GBpm

Good luck!

Huh? Veritas don't make a driver for the adaptec card, they never have, probably never will..

Any errors in the System log?

network or local backups?
