I have Updraft on each of my sites. Each week I go to the extensions menu and refresh the remote backup connections, then scroll through to make sure backups are being taken of each site.
The problem is that if Updraft has disconnected, I can’t tell.
I’d love to look under Manage Sites and have a column for last backup date. Or even just that Updraft is installed/connected.
So if the child site is connected to the Dashboard, and the UpdraftPlus plugin is active on the child site, the extension is connected. We are not aware of situations where the UpdraftPlus extension by itself can get disconnected.
As for the table column that would show the last backup date - first you need to select UpdraftPlus as the primary backup system on the Dashboard > Settings > General settings page.
