Abstract
A remote data recovery system is determined to be unsuitable for communications. A stream of source system storage changes associated with an object is received at a backup system from a source system while the remote data recovery system is unsuitable for communications. The backup system is utilized to generate one or more reference restoration points based on the stream of source system storage changes associated with the object. The remote data recovery system is determined to be suitable for communications. In response to determining that the remote data recovery system is suitable for communications, a hot standby of the object hosted by the remote data recovery system is updated to a reference restoration point generated by the backup system prior to the remote data recovery system becoming suitable for communications.
