Abstract: A backup defect detection system includes a backend and an agent. The backend includes a plurality of file servers backed by a database. The database contains data associated with one or more users. The agent is installed on a user's computing device and in communication with the backend to scan a user's selected folders to determine new or changed files and upload the new or changed files to the backend. The agent is configured to generate one or more logs recording the success or failure type of a file backup and transmit the logs to the backend. The backend is configured to generate a report from the logs, filter and prioritize the report based on a set of user defined importance for each error type and provide the filtered and prioritized report for further action. Related apparatus, systems, techniques and articles are also described.
