I have been doing some testing (nothing new)
things went wrong, stuff disappeared (nothing new)
But when I went for a backup to restore an older copy, the backups are way out of date.
Here is a screenshot, look closely at the dates, the red arrows point to the working .svo it has todays date,
and the last half hour.svo backup, which shows a date 3 weeks ago, apparently the half hourly ones arent working, they are all 3 weeks old.
The weekly backups seem to be working by the dates, the daily ones are over 2 weeks old.
I would expect to be able to go back to a backup half an hour ago or one hour ago, but there none there.
