I’m using `vimwiki` for years and love it.
I also tried Obsidian but I need it also mobile and I cannot define a storage path for my files.
I just like the freedom, minimalism and flexibility of vimwiki.
There's a community plugin called "Remotely Save"[0], which allows you to sync your data on s3-like services. I use this with Backlaze's 10gb free plan.
It took a minute to set up but runs without any issues for me.
