I’ve just looked at our backup history and can see backups from the following date:
That seems like an odd spread, from what I recalled we previously had the last seven days.
We have recently changed the site name as part of our shift from using discourse in the title. The original change was on August 12, although it was tweaked again on the 13th. Starred backups above all bear the same name.
As the backup name includes the site name, is there any chance the rename is responsible for this odd distribution of dates? It’s a little odd to have six consecutive days dating back more than a week and only one backup from the past seven.
