Setting up a NAS-Data-Protection policy
You must set up NAS data protection policy to protect your assets.
To set up a policy for NAS data protection
- Open the NetBackup Administration Console.
- Click NetBackup Management > Policies in the left pane.

- From the Policy type list, select NAS-Data-Protection
- From the Policy Storage list, select Storage Lifecycle Policy.
- (Optional) Select the Take checkpoints every check box and enter a value in minutes.
- The Perform snapshot backups option is selected by default. Configure the snapshot options:
Snapshot Type: Select the appropriate snapshot type. By default, Auto option is selected which enables NetBackup to automatically determine the snapshot type to be used for array snapshot.
Snapshot Manager: Select the NetBackup Snapshot Manager host which communicates with the storage array to perform the snapshot operations.
Note:
The Snapshot Type Auto is supported only with backup host version 10.0 onwards.
- (Optional) To track changes between two snapshots, select the Enable vendor change tracking for incremental backups check box.
Note:
At a given time, you can only use either the Enable vendor change tracking for incremental backups or the Use Accelerator check-box.
- In the Dynamic Data Streaming Attributes section, the Allow dynamic streaming option is selected by default. Configure the following attributes:
Note:
With this setting, the Allow multiple data streams option is also selected.
Maximum number of streams per volume
The number of streams per volume must be between 1 to 20. The default value is 4.
Maximum number of files in a batch
The number of files in a batch must be between 1 to 2000. The default value is 300.
