Create tamperproof Snapshot copies for WORM storage

Contributors netapp-manini

You can create tamperproof Snapshot copies of write once, read many (WORM) files on a Cloud Volumes ONTAP system and retain the snapshots in unmodified form for a specific retention period. This functionality is powered by the SnapLock technology, and provides an additional layer of data protection and compliance.

Before you begin

Ensure that the volume that you use for creating Snapshot copies is a SnapLock volume. For information about enabling SnapLock protection on volumes, refer to Configure SnapLock.

Steps

  1. Create Snapshot copies from the SnapLock volume. For information about creating Snapshot copies by using the CLI or System Manager, refer to Manage local Snapshot copies overview.

    The Snapshot copies inherit the WORM properties of the volume, making them tamperproof. The underlying SnapLock technology ensures that a snapshot remains protected from edit and deletion until the specified retention period has elapsed.

  2. You can modify the retention period if there's a need to edit these snapshots. For information, refer to Set the retention time.

Note Even though a Snapshot copy is protected for a specific retention period, the source volume can be deleted by a cluster administrator, as WORM storage in Cloud Volumes ONTAP operates under a "trusted storage administrator" model. Additionally, a trusted cloud administrator can delete the WORM data by operating on the cloud storage resources.
