Community check your backup data

(Trystan Lea) #1

For a long time now we have been running an automated incremental daily backup of all feed data on

The backup data is stored on 3 external drives that are attached to each of the 3 storage servers that is running on. There is a daily process that copies over the new data recorded every day. This will allow relatively quick restoration of a storage server in the event of a failure, as it will be a matter of plugging the backup drive in to the new machine and copying the data across.

In order to double check that the backup’s are ok I’ve implemented a way to load up the backup data in the graph interface, if you wish to check up on your feed data backups this is how to do so:

To check your feed data backups:

  1. Open a feed in the emoncms graph view:

  1. Add ?backup=true to the URL:


You should now see the same data but without the most recent hours since the last daily backup ran:

Im aware that a better solution for quick restoration is to replicate each storage server continuously over a second machine in a way where its possible to switch between one or the other. We plan to do this once we implement the subscription charge which will help us afford the extra server costs.

Im also developing an easier way to backup to a local emoncms installation and even upload a local installation to Its called the sync module: It works well for backup already but I have not yet enabled the upload part on

How do I use the sync module module
Copying feeds and dashboards over to another online account?

Hi Trystan,

Paul just mentioned it might be possible to upload dashboards to online accounts using the sync module. Is this possible? How far off is the upload function from being enabled?
