Systems and methods of estimating and managing storage device degradation

Abstract

Systems and methods of estimating and managing storage device degradation are disclosed. Degradation of the data storage device is estimated during which a degradation rate and a probability of failure of the data storage device are determined. When the probability is greater than a given threshold, a corrupted sector of the data storage device is identified by scanning a surface of the data storage device. Based on the analysis of at least metadata of the data, a value level (i.e., the value of the protected data to the user) is determined for at least the data in the sector near the corrupted sector to determine that the data may be lost, and a copy is established based on the value level of the data and the degradation rate of the data storage device.

Description

technical field [0001] The present application relates to computer technology, and more particularly to systems and methods for estimating and managing storage device degradation. Background technique [0002] Computer systems depend to a considerable extent on data storage devices, such as magnetic hard drives, that store a variety of data including operating system files, application programs, system data, user data, and more. It is important for the trouble-free operation of computing systems to have data storage devices functioning properly, but the reality is that data storage devices often fail or fail suddenly over time (eg, due to bad sectors or file system errors). In this regard, there is the problem that an undesired failure of a data storage device (hard disk) can lead to damage and / or complete loss of data / files containing stored information valuable to the user. Such a hard disk failure can result in an inability to boot the computer (eg, due to damage / loss of...

Problems solved by technology

It is important for the trouble-free operation of computing systems to have data storage devices functioning properly, but the reality is that data storage devices often fail or fail suddenly over time (for example, due to bad sectors or file system errors)

In this regard, there is the problem that an undesired failure of a data storage device (hard disk) can lead to damage and / or complete loss of data / files containing stored information of value to the user

However, these solutions have one or more of the following disadvantages: First, the copy of the damaged file may be too old, at which point the damaged file does not exist in the copy or the damaged file has an old version that is not suitable for use

Second, recovery itself can result in further loss of some data

As a result, the user will not know which files are corrupted and which are recovered

Third, the copy may not include the damaged file if, for example, it excludes or blocks it during the generation of the copy

Fourth, if a hard disk failure occurs, making it impossible to start the operating system on the computer, the user may not be able to recover anything

Furthermore, another pressing issue is to be able to prioritize data (files) to ensure that the most important data integrity
