Hi,
Our backup is currently running for nearly 17 hours while it used to take about 12 hours. The problem first occured after installing a batch of Windows updates. After uninstalling those updates, the performance never returned to "normal".
Last weekend we decided to take a dedicated server and reinstall our backup solution. The server which hosted Backup Exec originally was a relative old Dell Poweredge 4400 server which also hosted al lot of other applications like Symantec Antivirus, Microsoft SUS etc. etc.
The new enviroment consists of:
Server
HP/Compaq Proliant DL380 G2
2x 1400MHz CPU
1536Mb RAM
2x 9,1 Gb 10K RAID1 for OS
3x 18.2Gb 10K RAID5 for Backup Exec
HP/Compaq Dual Channel Ultra3 SCSI Host Adapter (originally from a Proliant ML350)
HP/Compaq NC6136 1Gbps Fiber NIC
Tape Drive
Sony Storstation LIB-162 (library) with 2x AIT-3 drives
Drivers from latest driver pack from support.veritas.com
OS
Windows Server 2000 SP4 with all applicable hotfixes
Backup Exec
Symantec Backup Exec 10d with all applicable hotfixes
Remote Agents with AOFO
Exchange Agent
We have one central backup server which processes all our servers over a 1Gbps fiber network. I have split our daily full backup in two jobs: one consists of the system drives, system states etc. of all our servers (about 10) and one job for all our data (about 300Gb) which is located on a HP/Compaq Moldular SAN Array 1000 with two nodes running Windows 2000 Advanced Server clustering.
The job which processes the servers runs fine within a 7 hour time frame, the other job is running 18 hours with an average throughput of 300mbpm. It used to run over 500mbpm and took just over 12 hours.
I have updated the firmware and drivers for every device I can think of and installed all the hotfixes for both Windows and Backup Exec. The only problem I encountered there was with the SCSI card. Accoring to the HP System Management Homepage the SCSI card is a HP Dual Channel Ultra3 SCSI adapter but when I try to download and install that specific driver, Windows tells me that it is not the correct driver. If I ignore that warning and install it anyway, the card does not start after rebooting Windows and gives an exclamantion mark. When I roll back to the original Microsoft driver, the card is identified as a Symbios Logic 875SID, 2290x PCI SCSI Adapter.
Does anyone have an idea how I can increase the throughput of my backup?
Thanks,
