You can deploy multiple remote backup repositories to have a local target for each location where a backup with VEB is needed. All the different repositories can be managed by the same central VBR server, as long as there's a vpn to connect all the repositories and the VBR itself.
Than, you can also create backup copy jobs to replicate backups from each remote location to the central VBR repository.
