thank you! i think i tried to give a local path but vite build is not success, (fs error) and i also didn't have time to further troubleshoot it. When i have more time, definitely going to try again with your solution

Hi there, have you try to check if this is permission issue. I always have the permission issue with AppImage. Start SiYuan with --no-sanbox and see. I end up installing the deb package, that at least fix the permission correctly for me

Yes! Just come to know that Cloudflare also has its S3 compatible storage, 10GB is unlikely to finish, even you did, only 0.015$ per month. It's quite cheap consider the number of requests and storage given.

some other user on youtube ask for a walkthrough, just created a post here to cover how to configure s3 sync with SiYuan. Configure SiYuan for S3 sync
btw, the syncing works really well.
