So creating another partition would work…but it seems that it would cause issues for Windows users since from what I understand will only mount 1 partition (even if you have multiple partitions to mount). MacOS doesn’t have that problem but I want to make sure this works for everyone.
All that said, what I ended up doing was expanding the “/boot” partition (the one that does mount when the SD is connected) and then updating the code so it’s more flexible and can save there instead.
Shrinking and expanding the Pi partitions is definitely much more involved so what I did instead was create an image from a new clean setup. This way all you have to do is flash it to the SD, pop it into the Pi and you are ready to go. I figure this may also allow people who don’t want to get into the technical details to still be able to use it! (Also, I still have instructions on Github if you do want to setup manually).
This image gives you over 1GB of backup space. If you want more, you can follow the instructions on Github to expand to a larger SD card size.
- Download the OPZgo image here.
- Flash to a SD card using Etcher.
- Plug it into your Raspberry Pi and you’re ready to start making backups!
Thanks everyone for the suggestions and feedback so far!
