The last backup I did was back in Aug '19 and the compressed file was 60MB is size.
I have a new 64GB card to replace the old one, but is there a way to copy the old SD card onto the new one
so I can then safely backup my data.
I’m also probably a couple of years behind the latest EmonSD version, so I guess I should also upgrade to the latest.
Can anyone give me some pointers, or a link to a guide?
It is on my todo list to fix the partition rezise. However, I think that @TrystanLea has set the script so it fixes the rootfs and the data partition is expanded to fill the rest of the card. It does mean the rootfs is a little small if you want to do other things but OK if just for EmonCMS.
The command remount is something of a misnomer. Viz.:
Remounting a filesystem means changing the options that control operations on the filesystem while it is mounted. It does not mean unmounting and mounting again.

A root partition is a type of partition within the Windows Hyper-V virtualization environment that is responsible for running the hypervisor. The root partition enables the execution of primary hypervisor software and manages the machine level operations of the hypervisor and created virtual machines.
