Abstract: Systems and methods are described herein for detecting the inadvertent modification to or deletion of data in a data store and taking automated action to prevent the deletion of data from becoming permanent. The described techniques may also be utilized to detect anomalous changes to a policy or affecting storage of data and taking automated action to mitigate the effects of those changes. In one example, events generated as a result of requests to perform operations on data objects in a data storage service may be obtained, where at least some of the events indicate a failure to fulfill respective requests. Data from the events may be input into a model to detect an anomaly indicative of inadvertent modification of data. As a result of detection of the anomaly, a set of operations may be initiated or performed to prevent the inadvertent modification of data from becoming permanent.

Abstract: An upholstered folding chair includes a chair frame, a base member permanently attached to the frame, and an upholstered insert configured to slide into and removably interlock with either the base member or the chair frame. The base member includes a retaining rim, which covers and protects at least some of the edges of the upholstered insert, and the base member and upholstered insert may have interlocking members which become hidden between the base and insert when the two are interlocked together. The base can be either a back base for receiving and supporting an upholstered chair back insert, or a seat base for receiving and supporting an upholstered chair seat insert.
