A system for maintaining a repository replication system includes an interface and a processor. The interface is to receive a request to modify a repository, wherein the repository comprises repository copies. The processor is to determine whether modifying the repository resulted in an indication of an error, wherein the indication of the error is based at least in part on a plurality of checksums, wherein a checksum of the plurality of checksums is associated with a repository copy of the repository copies; and in the event that modifying the repository resulted in the indication of the error: queue a repair request to repair the error; and execute a repair process to repair the error associated with the repair request, wherein executing the repair process occurs asynchronously to queuing the error request.
