This is an interesting way to receive data but I wish there was a way to do the reserve. Take handwritten/handled input into a computer. I asked this question the other day if I could somehow input my handwritten notes into programs like Trilium (or logseq whatever) and memos. OCR/HCR seems to far behind still so I am unsure. That would certainly be a cool method!
I checked my local backup server and I have two directories:
/home/share for backup files
/home/app data for backup appdata
My main server which unfortunately runs unraid is structured like
/mnt/user/array/media
/mnt/user/array/Nextcloud
/mnt/cache_ssd/appdata
