After a data loss, which backup is restored first?

When restoring data after a loss, the most logical first step is to restore the most recent full backup. This backup contains a complete copy of all the data as it existed at the time the backup was taken. By starting with the full backup, you set a foundation from which to recover any additional changes that may have occurred since that backup.

The full backup provides a comprehensive snapshot, making it easier to evaluate what data has changed in subsequent backups. After restoring the full backup, any incremental or differential backups can be applied to recover the latest changes. Incremental backups only include changes made since the last backup, while differential backups include changes made since the last full backup. Therefore, restoring the full backup first ensures that all data is present before applying any additional updates.

This method minimizes the risk of data loss and allows for a more systematic recovery process. It also helps ensure that the data structure is intact, which is crucial when dealing with databases or complex data systems.
