Abstract: A method (300) includes obtaining a key status (164) for a first cryptographic key (162). The first cryptographic key is used to encrypt replicated data (22) of a first replication instance (172). The method also includes determining, based on the key status, that the first cryptographic key is inaccessible which causes the first replication instance to be unavailable. In response to determining that the first cryptographic key is inaccessible, the method includes scheduling a second replication instance to be unavailable after a threshold amount of time has passed. The second replication instance includes replicated data encrypted by a second cryptographic key that is accessible. After the threshold amount of time has passed and when the first cryptographic key is still inaccessible, the method includes setting the second replication instance as unavailable.
