Abstract

Various systems, processes, and products may be used to manage remote data replication. In particular implementations, a system and process for managing remote data replication may include the ability to store versions of a disk at a first site, a second site, and a third site. The version of the disk at the first site may store input/output for a host system, the version at the second site may be a synchronous replication of the version at the first site, and the version at the third site may be an asynchronous replication of the version at the first site. The system and process may also include the ability to synchronize the version at the first site with the version at the third site if the second site is unavailable and synchronize the version at the second site with the version at the third site if the first site is unavailable.
