Full Backup
Backs up all selected files.
Differential Backup
Backs up selected files that have been changed. This is used when only the latest version of a file is required.
Incremental Backup
Backs up selected files that have been changed; but if a file has been changed for the second or subsequent time since the last full backup, the file does not replace the already-backed-up file, rather it is appended to the backup medium. This is used when each revision of a file must be maintained.
Delta Backup
Similar to an incremental backup, but backs up only the actual data in the selected files that has changed, not the files themselves.
