Recovering data from backup after it stopped working

[Marty P]

Hi all,

Thanks again Thomas for creating this, it's been working great for about 10 years now and very useful.

For some reason it seems to have stopped updating the last few days and I'm trying to fix it. On the main page it just kept refreshing with the same readings and showing 0 data for a few days.

I restored an old image and it worked fine, I then restored from a backup from several months ago and it worked ok. I restore from the last backup after the issue and the issue comes back. It seems to see the device etc. and I have tried starting and restarting the service. Something seems to have broken in the last backup but I'd like to get all the data back from it if I can. It also wasn't showing the graph anymore under the EnviR tab but it is now on the backup from 2 months ago.

Any ideas at all please?

I tried browsing to \\IP\Web folder but it asks for credentials and the ones I use to access the Pi don't seem to work from Windows for some reason. I believe I could copy the data from the Web folder in the broken image to the Web folder in the working one to get the data back possibly? Or possibly copy the data from the broken one into the below?

Do you have enough free space on your sd-card?

Take a look in the measureit.log

Many thanks, I have ran the debug as attached and also ran the command to check for disk space. I tried loading the latest ISO from last month too and used the Raspberry Pi imager but it fails verification. I don't know how I could check which version I have as I have been running it since 2018?

If I restore my backup from 2 months ago it works again, shows accurate current amount and the graph too. Only issue is I have lost 2 months of data.

I've bought a 16GB SD card as this is only 8GB, It's an old Model B Pi 1.

I've put the image back on the SD card from when it was broken and restored the backup from March and it's working again.

I can now see the graph again and it shows the live data ok but missing March to June unfortunately. I don't know if there might be a method for just recovering that?

It tends to be a little slow to load mainly when expanding the monthly cost data (from 2018 to now), I'm thinking that's because I have a Pi Model B 512MB, I'm thinking of getting a newer Pi with a 16GB SD card.

So it does seem to be something contained within the latest backup which is broken somewhere.
