Sorry! Was drinking! It was probably lost in the wall of text.
I only got up to 3 months, with a retention policy of 7day, 4weeks, 3months as the dedupe is very good. If I didn’t have dedupe it would be only up to 4 weeks.
The reasons are, I notice if I’ve lost a file in <3months and if I lose a drive the latest backup would be the one I restore from. (Yesterday in this case).
Why would I ever need the 1 year old backup?
