I'm seeing terrible backup performance on my backup servers, the speed has slowly degraded over time. Although, I have never seen speeds higher than 1MB/s. (We have it set to do no more than 2 backups at a time.)
Here is our setup: Our network is all 100Mb between servers, and switches, and 1Gb between switches. So, there is enough network capacity for decent performance. The servers being backed up, all have either RAID1 or RAID5 arrays consisting of 15K RPM SCSI drives. All RAID is done in hardware. The backup servers are using 7200RPM SATA drives, connected to 3ware 8500 or 9000 series controllers. Two the backup servers are using RAID1, and the other is using RAID5. Our backup servers are running CentOS 4.4, with ext3fs for the backup partition. I have noatime enabled, and data=writeback set to hopefully improve performance. On our backup servers, they are all showing a very high wait during backups. Here's a screenshot from one of them http://www.publicmx.com/fh/backup2.jpg. At the time it was doing two backups, and a nightly. Any advice on improving performance, would be much appreciated.
