Regarding the suggestion to increase backup streams, as per discussions from a few years ago, PostgreSQL backups in Commvault did not support stream configuration.
I also cross-checked with the L2 team on the incident channel, and they confirmed that the streams option is currently greyed out for PG instances.
While only about a week remains for the HSX migration, it would be helpful to explore any long-term approach to improve backup throughput—apart from increasing streams—especially for critical databases.
Please let us know if there have been any recent changes or alternative options we can consider.
Thanks & Regards,
