Modifying the Number of Streams for Backups

You can modify the number of streams used for backup operations for FSBasedBackupset subclients and DumpBasedBackupset subclients. You can configure multiple streams for data backups.


  • Single stream is used for Log backups.

  • Multi-stream backups from FSBased backupsets will work only for PostgreSQL clients with Indexing Version 2. By default, Indexing Version 2 is enabled for new clients that are created in Feature Release 11.20 and more recent versions. To migrate clients with Indexing Version 1 to Indexing Version 2, execute the Upgrade to IndexingV2 workflow.
