Also, unless if a data set overwrite occurs soon after it is detected and recorded, GTF trace data is usually wrapped (i.e., overwrites itself) thus eliminating the need for diagnostic data and making it unusable by service personnel

Abstract

The invention relates to dataset overlay protection. A method for preventing data overlays in a data storage system is disclosed. In one embodiment, such a method detects a write operation directed toa storage area of a data storage system. The write operation includes one or more of a format write operation and a full-track write operation. Upon detecting the write operation, the method determines a data set that is associated with the storage area. The method analyzes metadata associated with the data set to determine whether the storage area contains valid data. In the event the storage area contains valid data, the method performs a data protection operation that prevents execution of the write operation and / or logs details of the write operation. A corresponding system and computer program product are also disclosed.

Description

technical field [0001] The present invention relates to systems and methods for preventing data overwriting in a data storage environment. Background technique [0002] Data produced by computing systems is often susceptible to errors. For example, production data is highly susceptible to errors in a network environment where multiple users may access the same production data at the same time. One type of error that can occur in such environments is dataset overwriting. Due to this error, data is incorrectly written to previously stored data, thereby corrupting and possibly causing the irreversible loss of previously stored data. For example, data overwriting may occur when data from a first data set is incorrectly written over data from a second data set. This could be the result of bugs, malicious activity, human error, etc. In environments where production data is mirrored from a primary location to a secondary location, errors associated with dataset overwrites may a...
