I would love to use Obsidian Sync in a non-GUI mode to sync my Vaults to disk for backing up.
I would use a 64 bit Raspberry Pi, running a 64bit OS with no GUI.
This would potentially work well within a Docker container, where the Vault is stored outside of the container on the local filesystem.
Alternatively, if it’s possible to write a separate Sync program, this would also be fine.
