US Patent 11042454 Restoration of a data source

Restoring data to a data store that suffered corrupted data over a time period is disclosed. A system may provide an interface to specify a time window and filter conditions for identifying corrupted data in an object in a data store, such as, but not limited to, a corrupted NoSQL table. Corrupted data is identified by applying the filter conditions to change logs for the data object (e.g., the No SQL table) in the data store. Repair operations are determined for individual items identified via the filter conditions. Identified corrupted data for items may be corrected, from change logs or backup data in some instances (e.g., data may be deleted, or updated or replaced with data from a backup of the data store when necessary).
