No, there is not, and there's a reason for that.

The longer the backup process runs, the more likely it is we hit a server limit. I know that as soon as I implement something like that people will start trying to upload to three different storage providers and go all Pikachu surprised face that the backup now takes 4 hours instead of one, and their server is killing it.

Beyond that, there are many issues on how to handle multiple uploads.

Has the backup failed to upload if one of the storage providers failed to receive the upload? If not, how many is not enough?

How do we present the multiple uploads in the interface without overwhelming the user?

How do we handle the case of a backup having uploaded to some storage providers but not all?

How do we handle the case of a backup not having uploaded to any storage providers, but having stopped uploading at a different part file?

There are many, many more problems, but these are the simplest ones everyone can grasp. No matte what you answer to the questions above, I can guarantee that if I ask another 9 users I will have at least 20 different answers...

I have always recommended a simple solution. Run your backups uploading to a storage provider. Use something like rclone to download the backup archives locally, and optionally upload them to one or more alternative locations. Rclone is great; it even has a GUI for people who can't be bothered with the terminal!

Midnight Commander is a great TUI application; I have been using TUI file managers since the early days of Norton Commander (the inspiration for mc) on MS-DOS. On Android I have Total Commander which keeps the same vibe (unless I drop to Termux in which case I use mc). While very capable, it is also very much manual.

Rclone is more geared towards automation. After initial configuration I can do something like rclone cp scaleway:backups-bucket/example.com/site-20260* nas:backups/example.com --max-age 1w  to make sure that last week's backups stored on my Scaleway bucket are fully synced on my NAS – and I can run it on a CRON job at 4am when my Internet usage is otherwise nil.

Ah! Yeah, that makes sense.
