Full backups perform a complete copy of all designated data every time the job runs. This means each backup session captures every file, regardless of what was backed up before, creating a self-contained restore point. Because you don’t rely on previous backups to reconstruct the data, restores can be done from that single backup image. The trade-off is that full backups take longer and use more storage, since every run duplicates all data. In contrast, differential backups copy only what changed since the last full, and incremental backups copy only what changed since the previous backup, which is why they don’t match the “copy everything every time” behavior. Synthetic backups, while involving full images, are created by assembling data from earlier backups rather than copying all data anew on every run.
