For volumes larger than 100 GB, PowerProtect Data Manager version 19.14 and later can protect PVCs using multiple file system agent streams through a new annotation. Adding the annotation
ppdm.config.fsagent/streaming_mode: concurrent
to the PVC can improve performance and reduce backup latency by up to 50 percent.
The number of streams is determined by the controller and corresponds to multiple threads and DD Boost connections. To avoid the overprovisioning of streams and impact to CPU, the maximum number of streams is 8.
For example:
streams_count = min(upper(volume_size / chunk_size), 8
