DATA PROTECTION AGAINST MASS DELETION BASED ON DATA STORAGE PERIOD: abstract simplified (17714855)

• This abstract for appeared for patent application number 17714855 Titled 'DATA PROTECTION AGAINST MASS DELETION BASED ON DATA STORAGE PERIOD'

Simplified Explanation

The system and method described in this abstract aim to prevent the accidental or malicious mass deletion of data in a data storage system. The process involves marking blocks of data to be deleted and then removing them through a garbage collection operation. By analyzing past deletion patterns and setting user-defined thresholds based on data age, the system can identify any significant deviations that may indicate a potential risk. If a deletion exceeds a certain threshold, the next garbage collection operation is delayed, allowing the user to investigate the deletion command and restore any necessary data. However, certain conditions, such as abnormal deletion periods or new system installations, can override this delay to ensure efficient operation.

Original Abstract Submitted

Embodiments of a system and method to prevent mass deletion of data in a data storage system. A data deletion operation comprises a delete operation marking blocks to be deleted followed by a garbage collection (GC) operation to remove marked blocks from storage media. Based on historical information regarding deletions per GC cycle and certain user-defined thresholds based on data age, the storage system can detect any significant deviations as potentially dangerous. If a deletion in excess of a deviation threshold is detected, the next GC operation is skipped to provide a delay period during which time the user can investigate the data delete command and restore data if necessary. De-risking conditions such as known abnormal high deletion periods or new system installation can be used to override any garbage collection delay.
