SnapMirror S3 automatically resynchronizes bucket contents when a previously unavailable source bucket becomes available after takeover. Creating an ONTAP S3 mirror relationship requires CA certificates for both the source and destination SVMs. SnapMirror S3 does not replicate users, groups, or policies, and source and destination users may use the same access and secret keys.

Because all ONTAP S3 communications mandate TLS/HTTPS encryption, establishing a secure SnapMirror S3 relationship requires valid Certificate Authority (CA) certificates installed on both the source and destination Storage Virtual Machines (SVMs) to mutually authenticate and establish encrypted sessions. Statement B is incorrect because SnapMirror S3 replicates purely object data and object metadata; it does not replicate SVM-level S3 users, user groups, or IAM access policies, which must be provisioned independently at the destination. Statement D is incorrect because user credentials (access and secret keys) do not have to differ and can be mirrored or aligned between endpoints to simplify application access.
