Thanks for the advice Mike. This is just my home setup with one desktop 
wired to another for backup. I use grsync but I think I must have 
forgotten to tick the save users and groups boxes on my last backup. I 
usually do a total backup of my home directory every Wednesday but I 
have had some problems recently so I missed the last one. Updating 
ubuntu lost me some data - like I say 'don't ask' I'm sure it was my 
fault. It will take me a day to re-key that data so it isn't too bad.
It keeps me outa the pub don't it?
