Vault and Rclone

Does any know if Vault can work with RClone (https://rclone.org)?

My use case is that I have multiple dev clients and I would like connect them to the Vault on the a remote backend. I am thinking that I can have a local Vault server that be configured with a remote backend.

No, you absolutely cannot have external file synchronization software changing the Vault storage on disk underneath a running Vault server.
