I've used these scripts multiple times without any issue when backing up/restoring on same/similar hardware. Newer versions of Plex seem to download drivers to the folder that we are backing up/restoring. When migrating from an 8th-gen Intel to a 13th-gen Intel machine, I installed Plex on the new machine, which downloaded the correct driver. And then when I restored the backup, all the data was imported correctly and all my data was showing up correctly! However, it overwrote the driver and was causing some issues where HDR Tone Mapping hardware transcoding wasn't working! However, hardware transcoding worked fine when HDR tone mapping was turned off. I uninstalled Plex, and I added --exclude="Drivers/" to line 41, ran the restore script again, and now everything works great!

Thanks again for this script (and the backup script as well). They are a lifesaver, especially for someone like me who likes to tinker and is constantly changing things!
