US 10,853,194 B1 · Selective data restoration

Abstract

A selective data restoration technique is disclosed. A request to recover data in a dataset is received along with an identifier of a particular portion of the data to be recovered. The request may specify a time that indicates a desired recovery state (e.g., recover the values as they were at the time). Change data is determined for the specified time. For example, data stream filters generate recovery data by applying filters (e.g., keys) to a time window batch of the stream data. The stream data may correspond to changes to a data set, and the recovery data may correspond to only a portion of the dataset (e.g., a portion of a table). The system performs a recovery action, based on the recovery data, using the recovery data to automatically restore data in a data store, or providing the recovery date to the requesting entity, for example.

Dependent claims

A system, comprising:

a change stream store implemented via one or more hardware processors and memory, wherein the change stream store receives and stores stream data from data streams corresponding to respective datasets in a data store;
a data recovery service implemented via one or more hardware processors and memory, the data recovery service to:
receive a request to restore data in a dataset, the request specifying a portion of the dataset and a time;
retrieve, based on application of the time, a time-window batch of the stream data for the dataset;
identify restoration data for the specified portion of the dataset via selection of a subset from the time-window batch of the stream data;
and
perform a restore action based on the identified restoration data.

4 more elements

A method, comprising:

receiving a request to restore data in a dataset, wherein the request specifies a subset of the dataset and a time that indicates a first window of time;
identifying, based at least in part on the first window of time, a subset of log data corresponding to the first window of time, wherein the log data identifies changes to data stored in the dataset;
identifying data within the subset of the log data to replace corresponding data within the dataset;
and
causing only the corresponding data within the dataset to be replaced by the identified data within the subset of the log data.
