"Data deletion" refers to the process of permanently removing data from a storage medium or information system. This process is conducted to eliminate sensitive or obsolete data, to free up space, to comply with privacy regulations, or to ensure that no confidential information remains accessible. Data deletion can occur at various levels, including individual files, databases, or entire disk drives.
Typical functions of software in the "data deletion" area include:
Secure deletion: The software provides methods for securely deleting data that ensure the deleted data cannot be recovered, such as overwriting the disk with zeros or random characters.
Selective deletion: Ability to select specific files, folders, or records for deletion to enable targeted data deletion.
Automation: Automation of deletion operations according to predefined schedules or criteria to streamline the process and ensure that no data is left behind accidentally.
