NetBackup Client performance

This section describes how to measure and improve the NetBackup Client side performance. There are a number of variables that can influence NetBackup client disk I/O performance. These variables need careful planning and approach when backing up high performance NetBackup clients. Some of the key variables that can influence NetBackup client disk are:

  • Quality of storage array

  • Non-backup related concurrent disk I/O workloads, like an antivirus scan running during backup cycle

    Note:

    The disk I/O throughput on the NetBackup Client and NetBackup Appliance disk I/O throughput are different. The NetBackup Appliance disk I/O throughput is not related to the NetBackup Client performance.

  • RAID groups hosting multiple LUN's with diverse workload and many others

As deduplication disk I/O represents a major choke point on the NetBackup Client side and it is very important to plan for an optimal number of backup job streams to saturate NetBackup Client I/O throughput. Rule of thumb is to use number of disks in the storage array LUN RAID group reduced by 2 to get the maximum number of streams. This rule is a good starting point but it is important to keep in mind that other datacenter environment variables will influence the outcome.

Using tools like nbperfchk to test NetBackup client disk I/O and troubleshoot potential bottlenecks on the data path to the appliance is essential during system tuning exercise.
