1. A method, comprising:
determining that a remote data recovery system is unsuitable for communications;
receiving, at a backup system from a source system, a stream of source system storage changes associated with an object while the remote data recovery system is unsuitable for communications;
utilizing the backup system to generate one or more reference restoration points based on the stream of source system storage changes associated with the object;
determining that the remote data recovery system is suitable for communications; and
in response to determining that the remote data recovery system is suitable for communications, updating a hot standby of the object hosted by the remote data recovery system to a reference restoration point of the one or more reference restoration points generated by the backup system prior to the remote data recovery system becoming suitable for communications.
