Thanks very much for your thoughts and time.

It’s not the rsync that worries me, but the reduction & reporting of the data on my Desktop m/c.
As you say, rsync is pretty good at what it does - recognising partial file duplication & transmitting a canonical update / delta. [thanks Tridge!]

The monitoring m/c is going 24x7. If I try to rsync every copy of the page back to my Desktop, I’ll lose great chunks of data when it’s not running.
