@Jay It appears you released a new windows desktop app, and upon installing it now it again wiped out the entire backpus folder!!! This is something that needs fixing (is not an emergency but it should be fixed soon). My backups folder in my laptop is constantly backed up to my NAS, but many people will not do that, and wiping out their backups folder will remove any possibility of recovery from a failure.
Also, the installation of the desktop app this time took forever (obviously because it was removing a humongous backups folder). I was about to stop it because I thought it had stalled somehow. Luckily I didn’t and eventually it finished.
