Thanks Ronni, yes, I was confused.  Originally I was thinking "Online Time 
Machine" but that is too expensive as far as I can see. Neil's suggestion of 
offsite with swapping a couple of drives seems the way to go.  I have not only 
my own stuff but also critical material belonging to other people that I have 
trebly backed up at home but which needs an away from home repository and also 
easy access by others if I happen to suddenly cark it.  
Thanks for confirming what was more or less apparent, hope you are warm and 
snug at home today, cold wet and windy here right now!
