A NetBackup policy is configured to back up the following paths for a client:
Multi-streaming is enabled for the backups, and multiplexing is set to 4. Backup streams are running slowly.
Which step should the administrator consider to improve backup performance?
To improve backup performance, particularly when backups are running slowly, it is beneficial to back up only one stream from each physical device on the client. This approach minimizes I/O contention, which can occur if multiple NetBackup processes try to read simultaneously from the same physical device. By ensuring that each stream is dedicated to a separate physical device, the overall efficiency and speed of the backup process can be improved.
I think answer B is correct, because there would be I/O contention if several NBU processes read on the same client physical. consider using one data stream (with the new_stream directive) for each physical device on the client.
