Unstructured-This simply backups selected data manually. There is little organization and it is poor fodder for forensics.

Full System Backup-This is typically done on a monthly or bi weekly basis. It is highly recoverable.
Incremental-First a full system backup is performed. This establishes a baseline. Then future backups are only performed when the data has changed. Incremental systems are harder to recover than full system backup systems.
Differential backup-Similar to incremental. However, in Differential backup systems the changes are recorded. It takes longer, but it is easier to recover. You only need 2 files, the initial full backup and the recorded changes.
