Abstract
Embodiments for rotating encryption keys in a sized-based process by defining a threshold value specifying a maximum amount of data to be encrypted by a single encryption key, determining whether or not data currently ingested by the data storage system exceeds the threshold value, and performing a key rotation operation to use a new key to encrypt incoming future data if it does exceed the threshold value. A time-based process performs key rotation from an old key to a new key in accordance with a periodic schedule, determines if the key rotation operation is successful in rotating to the new key from the old key, and if the key rotation operation is successful then performing a subsequent key rotation operation in accordance with the periodic schedule, or if not successful sending a user alert and automatically re-attempting the key rotation operation.
