Protect your Raspberry PI SD card, use Read-Only filesystem

To remount the filesystem for writing, from the bash command line:
sudo mount -o remount,rw /
To put it back in read only mode:
sudo mount -o remount,ro /

Note you can also remount /boot in a similar fashion.

What needs to be done:
Most camera systems will set a volume label for cards that are formatted in-camera, so the scripts use that label to find backup targets as well as the storage drive. So you want to edit auto.sh and set the variables identifier_storage and identifier_target to something that makes sense for you. Canon uses “EOS_DIGITAL” so that’s what I have have in there right now.

Currently the scripts are also set to backup files based on their extension, for Canon this is .CR2 and .MP4. You’ll want to change these if you are shooting to .JPG (not raw) files or using another camera system that creates different file types / extensions.

Hopefully this doesn’t need to be said, but just in case:
When you download the image, you’ll get a .img file, then you’ll burn this image to a micro SD card using an image writer, if you’re using windows you can use Win32DiskImager, the same app that is discussed on the Raspberry Pi website. I’ve shrunk the image down as small as I could get it, but you’ll need at least a 2GB card micro SD card to fit it.
