The automatic backup feature of Discourse has a setting
backup frequency. However, I suspect that this setting does not control the backup frequency, but rather the backup period (where period = 1/frequency), i.e. when set to
4 my suspicion is that it would create a backup every 4 days and not 4x per day.
This is not clear in the user interface. The hint below the setting says “How frequently we create a site backup, in days”, which indicates that indeed this is the period and not the frequency. It also doesn’t indicate whether it accepts integers or floats.
I would suggest either changing the (label of the) setting to
backup period, or adding a little explanation that a setting of
4 would create a backup every 4 days. This would take away the ambiguity between “most likely explanation” and “actual literal meaning”.
