SnapLock is an alternative to the traditional optical "write once, read many" (WORM) data. SnapLock is used for the storage of read-only WORM data.
SnapLock is a license-based, disk-based, open-protocol feature that works with application software to administer non-rewritable storage of data.

SnapLock can be deployed for protecting data in the strict regulatory environments in such a way that even the storage administrator is considered an untrusted party.
SnapLock provides special purpose volumes in which files can be stored and committed to a non-erasable, non-rewritable state either forever or for a designated retention period.
