What would you recommend for Backup Exec and Quantum Superloader 3 Optimization?
Posted on 2009-04-08
Im not an expert in an expert in Backup software, or running backups in general so Im looking for the best way to optimize our Backup to our Quantum Superloader 3 using Backup Exec.
Currently I'm running Backup Exec 12 to backup to our Quantum Superloader 3. We have the LTO-2 drive in the Quantum Superloader 3, which according to the specs can transfer at a rate of 187.2 GB/hr of compressed data. We are currently have a job that is timing out on us since it's taking over 20 hours to complete.
We have the Quantum Backup Unit attached with a single SCSI cable straight to a backup server which is dedicated strictly for backup. The server is a HP DL320 G5p, which has 4 GB of ram, and a Xeon X3210 2.13 GHz CPU. Ive updated all firmware to the Quantum unit, as well as the HP server.
We are backing up from 5 separate servers which are all running Backup Exec Agents(2 DNS/ DHCP servers, 1 Exchange server, 1 Terminal Server, and File Server). We are backing up the system states and Utility Partition of each of these servers, as well as the Microsoft Information Store off the Exchange server, also all relevant files from the hard drives from each server. In total about 600 GB. Its in a single job which has been scheduled to run nightly.
The problem seems to be in the file transfer to the tape, Im currently only be able to get a job rate of 500 MB/minute, which is 30 GB/hr.
So the question is what is the best way to optimize my current setup to maximize the transfer of data to the tape, as well is there another way to pull the data which would help speed this process up?
