Dear Justin,
We plan to support distributed, fault-tolerant storage in rclone over the long term. The initial raid3 backend is our first step — it’s the simplest to implement and, for cloud storage, likely the most efficient model to start with.
We’re open to expanding this into a broader family of virtual rclone backends with more flexible layouts (such as RAID5) and potentially enhanced cryptographic options.
For now, we’re focused on integrating raid3 into the rclone backend ecosystem. Once it’s available, we’ll gather user feedback and evaluate the direction for more advanced configurations.
