Data backup and recovery involve safeguarding your data against loss and establishing secure systems for retrieval in case of an incident. This process entails copying and archiving computer data to ensure accessibility in scenarios like data corruption or deletion. Data can only be recovered from an earlier time if properly backed up. Data backup is a crucial element of disaster recovery planning, although it may not fully restore all system data and settings, especially for complex systems like computer clusters or databases. Cloud storage has become a practical solution for backing up significant amounts of data, eliminating the need for local storage. Additionally, cloud technologies enable automatic data recovery on mobile devices, enhancing convenience and security.
