Applicable customers: customers in finance, insurance, healthcare, and securities sectors with classified protection compliance requirements. New Feature/Specification: Snapshot Lock provides the write-once-read-many (WORM) attribute, allowing users to save and use data in a non-deletable and non-tamperable manner. When a snapshot is locked, no user can delete it. You must unlock the snapshot or wait for the lock to expire. This provides a high level of protection against accidental deletion and malicious damage to data. During the lock period, you can use the snapshot as normal.
