What NetApp SnapLock is

NetApp SnapLock is ONTAP storage software for creating disk-based data permanence on HDD and SSD deployments. It stores nonrewritable, nonerasable records that remain protected until a specified or default retention date. Retention features include Legal Hold, Event-Based Retention, and Volume Append Mode. Compliance volumes cannot be destroyed before retention expires, while a trusted administrator can delete Enterprise volumes or files. SnapMirror replicates WORM data while continuing to enforce retention periods, and the SnapLock compliance clock can prevent snapshots from deletion until an expiry. Administrators can manage logs, retention settings, fingerprints, legal holds, and the compliance clock through ONTAP REST API calls. NetApp cites certifications including SEC 17a-4(f), FINRA, CFTC, and national German-speaking requirements. Creating a volume requires an online SnapLock aggregate, license, and initialized Compliance Clock. SnapLock is available through API and self-hosted deployment, with pricing on request and no free plan.
