Does anyone know of any simple, light-weight cloud sync server systems that are open source?

I've had OwnCloud and NextCloud. I used their services for a while until i realized that after you lose a server and the amount of "prep" that goes into file/cloud storage is crazy. Not to mention that most cloud solutions require SQL databases and other crazy setup requirements. So, if you lose the database, you can still get the files, but you have to basically redo the entire sync and re-upload everything again... that is ridiculous.

I am looking for something lightweight and simple. Does anyone know of a database-less cloud storage that is secure and fast? I like the idea of being able to sync my phone storage so that it auto-uploads photos and videos, but I don't need that... Google does a fine job of syncing my phone data. I do want the simplicity of uploading and the freedom of setup. (if that makes sense).

I tried Minio and it is great except the security seems weird (password in a single file with no encryption) and you can't share a file longer than 7 days.

Thanks, and I appreciate any help.

Kick back, some other productive answers will be forthcoming.

Well... That just about sums it up... I thought I was crazy wanting something simple...

The problem you are trying to solve is not simple. To do what you want is a lot of work for the cloud provider. I just don't think you're going to find it for free.

Linux is a humbling experience sometimes.
Simple for whom? The user?

Owncloud >Nextcloud.
Dropbox is dead simple.
