Feature Request: Implementing 3-2-1 backup strategy

[toskium]

My current understanding of restic-windows-backup is that it only allows for one restic repository to save backups to.
With the PR #96 one can add additional parameters to employ rclone but it does not allow for multiple repositories.

What I would like to do is the following:

1. define local restic repository on a NAS
2. define rclone remote on some cloud storage
3. run restic-backup to store everything on the local restic repository
4. run rclone after restic-backup has finished and sync all the new files to the defined rclone remote (possibly multiple rclone remotes)
5. When doing restic-backup maintenance also do rclone remote maintenance to check if everything is in order.

Is this feature request in alignment with the project?
