About NetBackup WORM storage support for immutable and indelible data
NetBackup WORM storage server supports immutable and indelible data storage.
For more information, refer to the Configuring immutability and indelibility of data in NetBackup chapter in the Veritas NetBackup Administrator's Guide, Volume I.
A retention period lets you define a time for protecting the backup image. Once you define a retention period, MSDP stores a timestamp along with the image metadata to indicate when the retention period expires. After the retention period expires, the image data can be deleted.
You can set the following parameters for the retention period:
Lock Minimum Duration
Lock Maximum Duration
For more information refer to the Workflow to configure immutable and indelible data topic in the Veritas NetBackup Administrator's Guide, Volume I.
WORM storage supports the following retention period modes:
Compliance mode
Any type of user cannot overwrite or delete the data that is protected using the compliance mode for the defined retention period. Once you set a retention period for the data storage, you cannot shorten it and can only extend it.
Enterprise mode
Users require special permissions to disable the retention lock and then delete the image. Only the MSDP security administrator user can disable the retention lock and then the delete the image if required. You can use the enterprise mode to test the retention period behavior before you create a compliance mode retention period.
