Rclone won't take a consistent snapshot so you either need to shutdown the thing or use some other tool to export the data first

zfs/btrfs snapshot and then rclone that snapshot?

I think that'd break deleting incremental snapshots unless you tried uploading a gigantic blob of the entire filesystem, wouldn't it?

Meaning you'd need to upload full snapshots on a fixed interval
