SnapLock Compliance prevents anyone, including the system administrator, from destroying or altering files, volumes, or aggregates before they reach their expiration date.
To enforce WORM data retention, you require a secure time base, which ensures that the retained data cannot be deleted prematurely by changing the regular clock of the storage system.
SnapLock Compliance meets these requirements by using the secure ComplianceClock feature. The ComplianceClock is implemented in software and runs independently of the system clock.
