Suggestions
Database "backups" MySQL/influxdb or other
Would be nice to get all the data from app into a dB so we can play a bit with data in grafana for example.
There are two ways to but one isn’t possible I think.
-
Live updating the dB.. But this isn’t always possible.
-
Periodic backups: Try to connect to the dB. Write data to it..wait a hour.. And cycle again. AL the time the connection isn’t possible store the last successful point and next time a connection is there write all missing data to dB :)
