For anyone who has serious (I.e. $$$) need of that they already have tapes and optical WORM media though.
You can do something conceptually similar with any sort of NAS that provides immutable snapshots as long as the management and control is effectively out of band.
The out of band part is the key. Our SAN data has snapshots. The backups are written to another storage device that only has an API key to write them to B2 storage. An attacker would effectively need to completely compromise multiple admins in the organization to get at all the stages of data duplication, and frankly there is no additional line of defense for total compromise if the attacker is willing to wait for physical tape or disk swaps.
Fortunately for ransomware, time is money for them too.
