SolidBackup with Kopia

Use SolidBackup scripts to clone and sync volumes and make them available to a "backup VM" which also has Kopia installed.

Then, with these cloned volumes that need a backup accessible in this VM, define and run Kopia backup jobs to backup data to S3 or B2.

This may be suitable for department scale environments where different application owners can give the administrator access to their data for data protection purposes. The entire process is administrator-managed, there are no user-managed steps.
