Performance during Data Archive backups

Any backup on the Data Archive computer has the potential to impact performance. You can largely avoid this impact by using the recommended disk configuration. However, some impact is unavoidable because CPU resources and file system cache resources are consumed.

Monitor Data Archive during a backup to determine how the backup affects archiving rate and archive reads, and the CPU usage of Data Archive. Also, monitor the Windows Performance Counters Avg Disk Write Queue Length and Avg Disk Read Queue Length for the Physical Disk performance object. If the disk queue length is greater than one, then the disk is falling behind.
