Secure data replication systems and methods

A system comprising:

• a computer processor;
• and
• a memory including instructions stored thereon that, when executed by the computer processor, cause the computer processor to implement a policy inspector module that:
• responsive to receiving data indicating a new data distribution restriction, querying a subscription repository for an existing subscription (i) to particular data affected by the new data distribution restriction and (ii) associated with a subscriber data storage node, resulting in an identified existing subscription;
• and
• suspending the identified existing subscription.

A data management system comprising:

• a network interface device;
• a data storage device that stores data associated with a data replication subscription (i) by a subscriber data node to (ii) data stored on a publisher data storage node;
• a policy repository storing data defining first and second distribution policies governing replication of data by a distributor service;
• and
• a policy engine that performs operations comprising:
• responsive to receiving data indicating a new data distribution restriction, queries a subscription repository for an existing subscription (i) to particular data affected by the new data distribution restriction and (ii) by a subscriber data storage node, resulting in an identified existing subscription;
• and
• suspends the identified existing subscription.
