After weeks of incremental improvements, CloudSync has evolved into a robust and reliable sync solution for Obsidian vaults that writes directly to Azure, AWS and GCP cloud storage. The plugin is now thoroughly documented, tested with various static code analysis tools and in use by several Obsidian users.
While CloudSync is now stable for daily use, I am always looking to improve. If you enjoy finding edge cases, hidden bugs, and helping make software better, I'd love your feedback! Plugin will be submitted to Obsidian marketplace after the last push to bash bugs out from CloudSync.
