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.
