If you're using StoreVirtual as the underlying storage, then, definitely take a look at Veeam that integrates deeply with the said device, allowing you to use SAN snapshots during backup process. This, in its turn, dramatically improves RPOs and reduces impact of backup activities on the production environment.
Apart from it, you can install VB&R on the above mentioned physical server and connect tape device it. Such deployment would allow you to archive backup data to tape mediums on whatever basis you want to, using special tape jobs.
Cheers.
