I notice that there is sometimes a brief section of missing data when I look at my station in the online “dataview” tool, although I can see the data for that time period is all there in the local helicorder plot image. So my station had continued to operate and record properly, and I guess it was some momentary communication blockage to the server. Does such missing server data ever get filled in later, or is it gone forever once my local stations helicorder records get older than 7 days and are deleted?
Given that the online server-hosted dataset shows dropouts that my local device does not show on its own helicorder plots, I thought I would use the raw data directly for my offline analysis.
On my R-Boom hosted webpage under Settings / Downloads I see there are three buttons: SWARM, LOGS, DATA. The DATA button is a ftp:// link to the local device’s ip address. I can access it via anonymous ftp, but I see the directory is empty. Does the unit need to be set to OFFLINE mode, for the locally-recorded data to be available in this way?

Ah, nevermind I see what I’m looking for appears to be in /opt/data/archive/2025/AM/RC93C/HDF.D

Hello jbeale,
Yes, there seems to be a minor interruption in communications between the server and the station, resulting in the gap you highlighted.
As of now, the data doesn’t get filled back. However, future Shake OS updates will have this feature, so no gaps will appear anymore in such cases.
Your last message is also correct: all data that the Shake records can be found at this address: /opt/data/archive/ and then (also for all readers) YEAR/NETWORK/STATION/CHANNEL/<DAILY MINISEED FILES>.
As, sometimes, browsers block ftp requests as the ones coming from rs.local/, we have prepared a page with alternative data download methods: How to download your data.
Also, if you deem it necessary, you could consider a Cloud Backup, as another Shaker has set up: Cloud Backup - #12 by wmvanstone.
