Where Does Cumulus MX Store Weather Data?
Cumulus MX keeps weather station data, logs, and web templates in its install folder with config in Cumulus.ini. Back up the data folder regularly.
Last updated
Cumulus MX centers on its install folder. The data subdirectory accumulates monthly logs, dayfile summaries, and all-time records from the station. Cumulus.ini beside it holds station type, units, web settings, and alarms.
That folder is the backup unit: copy it whole with the software stopped. Exact layout may vary by version, so pair ini and data from the same release. Web templates render the public site from the same data; custom pages ride along in the backup. Monthly log gaps flag station outages faster than graphs.
Where Cumulus MX stores this, by platform
[CumulusMX folder]\data\
Logs and records in the data folder; settings in Cumulus.ini. Exact layout may vary by version. Back up with the software stopped, ini plus data together.
[CumulusMX folder]/data/
Same install-folder model as Windows, common on Pi hardware. Keep the software version matched between backup and restore.
Frequently asked questions
How do I back up Cumulus MX?
Copy the data folder with Cumulus stopped to preserve logs and dayfile records. The ini carries station settings separately. Restore both halves together; new installs with old data need matching software versions.
Where are station settings?
Edit Cumulus.ini with the software stopped, then restart and verify the dashboard. Most settings also live in the web interface, which writes the same file. Keep a dated ini copy before experimental changes.
