REVERSE REPLICATION TO ROLLBACK CORRUPTED FILES

The present invention extends to methods, systems, and computer program products for reverse replication to rollback corrupted files. When a computer system detects that a copy of a file includes inappropriate content, the computer system can coordinate with other computer systems (e.g., in replicated storage system) to determine that a viable (e.g., clean) copy of the file exists. The computer system can access the viable copy and replace the copy that includes the inappropriate content with the viable copy. As such, a computer system can "reverse replicate" a file rather than break a synchronization relationship. Reverse replication can be used to rollback a copy of an infected file to another (possibly earlier) copy of the file that is not infected. Embodiments of the invention can be used to rollback data files, such as, for example, pictures, videos, documents, etc.
