Sounds like you have sitemaps, items files etc, but not binaries backed up. So yes, you will have to reinstall bindings but they should mostly just pickup the items once installed (depending on how you’ve configured). Recommend going to SSD disk rather than SD or USB stick, less prone to failure. Also make sure you have genuine (proper amperage) power supply for Rpi (low amp power supply can cause file system corruption) and recommend taking an image after major updates as well as regular OH backups using the “openhab-cli” command (also ensure you get that backup off to alternate media) Or see my post here for tips on simple backup script, plus links further on in the thread on a how to for running an SSD disk with Rpi.
