Backup and restore to lastest EmonPI Image

Tags: #<Tag:0x00007f56bd5389d0>

I have taken a backup its 505mb
I loaded the image to a 16gb card and tried a restore got an error back about no disk Cannot write: No space left on device.

I found a 64gb card and ran sudo /opt/emoncms/modules/usefulscripts/sdpart/./sdpart_imagefile . waited 30 min the partition /var/opt/emoncms now shows 50.55gb free. but the restore still fails.

it looks like the restore uses /opt/openenergymonitor/data/upload

I dont know how to fix this.

Ah I think the backup file will be too big - it is a php limit that is set IIRC. I suggest using the USB restore method.

@TrystanLea another thing to mention in the upgrade documentation (i.e. what the size limit is).

The card reader I have is https://www.kingston.com/en/memory-card-readers/mobilelite-g4 which supports both SD and MicroSD.

Once the EmonPi has finished updating I can see in the logs its download the usb-import.sh I plugin my card reader but dont get the menu for the USB Import.

Will i have the same problem with backups?

I think I have managed to get the usb to work, needed to run it from SSH session.

32/64GB Cards a cheap, why are you still trying to use a 16gb card. I would like to see a automated nightly or weekly backup. Also to include an option to an external USB drive.

if you need some 64GB cards let me know and i will send an amazon voucher over…

Apologies, I missed merging the latest version of the backup module into stable. I have now done this, if you re-run the emoncms updater it should now appear.

Noted issue with location of upload and file size limit, I will move the upload location to the data partition as discussed in the other post. Thanks!

When you click backup where is the backup stored?

On import or export? They are different IIRC.

I have suggested a method in this issue https://github.com/emoncms/backup/issues/42 to modify the behaviour of PHP for the backup module (without editing the php.ini file).

You could create this drop-in so it modifies the behaviour for you.
