Systems and methods for data replication synchronization

A system comprising:

• a first server communicatively coupled to different servers and to one or more clients;
• the different servers;
• the one or more clients;
• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the system to perform:
• storing a first data object at the first server, the first data object being associated with a corresponding second data object stored by a second server of the one or more different servers and a corresponding third data object stored by a third server of the one or more different servers;
• receiving an update to the second data object from the second server;
• generating a version vector representing the updated second data object;
• generating a condensed form of the version vector, wherein the condensed form hides second server client information of any associated clients of the second server;
• transmitting the condensed form of the version vector to the first server or the third server;
• prior to or during scheduling of one or more import actions from the second server to the first server and scheduling of one or more export actions from the first server to the third server:
• generating a condensed import version vector representing an import data object to be imported by the one or more import actions, wherein the condensed import version vector hides the second server client information or hides different client information of any associated clients of a different server besides the second server;
• and
• generating a condensed export version vector representing an export data object to be exported by the one or more export actions, wherein the condensed export version vector hides first server client information of any associated clients of the first server, hides the second server client information, or hides the different client information;
• and
• selectively scheduling the one or more import action and the one or more export actions, according to ordering rules of the one or more import actions from the second server to the first server relative to the one or more export actions from the first server to the third server to synchronize, among the first server, the second server and the third server, the first data object, the second data object, and the third data object.
