NetApp C-Mode Multi-Streaming Backups

For NDMP NetApp C-mode subclients, you can configure multiple data streams to back up an individual content path on a subclient. After you configure multi-streaming for a subclient, the next full backup operation multi-streams the content path. If a content path is not completed during the full backup operation, the next incremental backup operation multi-streams the content path.

Multi-streaming for NDMP NetApp C-mode subclients is accomplished by looking up the subdirectories immediately under the subclient content path and backing up those subdirectories in parallel.

Note

The first incremental or differential backup after a full backup is a date-based incremental and only backs up files with a modified or created date newer than the full backup time.

Support

Multi-streaming within an individual content path is supported for the following:

  • Full backup operations when the subclient content paths are full-volume content paths.

  • Volumes must meet the following requirements:

    • The volume must be larger than 300 gigabytes.

    • The average subdirectory size must be larger than 20 gigabytes.

    • The number of subdirectories must be fewer than 5000.

    • The backup content root path must contain fewer than 20,000 files.

    • The volume cannot be a FlexGroup volume.

    • The volume cannot be a read-only volume or a snap-mirror volume.
