NetBackup status code: 6730
Message: The selected schedule type is currently not supported for the sharded cluster that has Feature Compatibility Version 4.2 or later.
Explanation: NetBackup doesn't support differential incremental backup of a sharded cluster which has Feature Compatibility Version of 4.2 or later.
Recommended Action: If you run an incremental on Sharded MongoDB cluster with version 4.2, refer to the MongoDB Administrator's Guide to change the Feature Compatibility Version of MongoDB to 4.0. Retry the operation with a full backup followed by incremental backup. If you do not want to change the Feature Compatibility Version, change the schedule type to only do full backups of this MongoDB instance. Incremental backups are not supported for a Sharded cluster with MongoDB version 4.4 or later.
