"OK I possibly fired off that question too soon. The backup utility says this.

Incremental: Backs up selected files only if they were created or modified since the previous backup.

Differential: Backs up selected files only if they were created or modified since the previous backup, but does not mark them as backed up. (i.e. the next differential backup will backup all the changes going back to the last full backup.)"
