PowerProtect Data Manager 19.9 Network Attached Storage User Guide

Protection engine parameters

A NAS protection engine can protect multiple NAS assets simultaneously by hosting separate containerized agents for backup and restore operations on individual shares. PowerProtect Data Manager selects a protection engine for each protection job based on engine availability.

Each protection engine has 24 parallel streams that you can use to protect NAS assets. Likewise, you can assign a number of these parallel streams to use for a particular NAS asset. By default, PowerProtect Data Manager allocates 8 streams per NAS asset, per backup operation. For restore operations, the default is 8 streams for share-level restore and one stream for FLR.

To improve performance, you can deploy more protection engines.
