Status is : no recent backup, should be : disabled

Recent versions should not consider a disabled backup as an error
As i understood this is computed via the lua alert scripts

However, not all backups are considered as disabled, some shows no recent backup

The default alert script window is empty.
I can t create a new script and copy paste it from a working server and save, it won t do anything when saving.

I looked at the archlinux package and apparently it doesn’t have a dependency on lua, would that be the problem?

These status messages seem totally random to me, see these 3 screenshots taken at ~30 minute intervals:
