I did not know that Restic was built on top of Rclone, but of course that makes a lot of sense. Thanks for contributing to a project that has made my life much easier!
rclone is just one of the backends you can use for restic. personally i find it far more performant to use a local disk for your restic repo (and keep the desired number of snapshots, etc there) and then use rclone to clone that repo to a cloud provider. personally i used backblaze's b2 api as it is generally cheaper.
restic is somewhat sensitive to the latency of the backend it uses.
