    How big is a TM backup please - is it the same size as the source?

    Same size and sometimes slightly larger depending how long its been backing up for.

    You will want at least double the size backup device than the original source, otherwise you won't be able to use the 'time travel' feature of time machine very well - it will keep deleting old backups
