I think that isn’t really a thing. Usually you would have a tape drive in a backup server for a network, and the backup server would have its own HDD, so you’d back up over the network to the HDD and then dump HDD to tape locally at close to the transfer speed of the disk. Higher capacity tapes have fast transfer and if your data source can’t kee up, the tape has to start and stop all the time, which slows everything down and wears everything out.

“Some TB’s” = single digits? Probably just back up to remote storage if you have enough network speed.
