Tape has no network path, no credentials, and no attack surface. Ransomware cannot reach a cartridge sitting on a shelf. That physical separation is why tape still holds a place in serious retention strategies, decades after it was declared obsolete.
The catch is that many backup platforms treat tape as a legacy afterthought.
DPX doesn't. Backup and tape are managed within the same platform, with support for multiple tape drives and current formats like LTO-9. Catalogic's commitment is explicit: tape support will never be discontinued. Combined with immutable vStor snapshots on disk and archiving to cloud or object storage, tape completes the offline layer of a resilient retention strategy.
It applies whatever your hypervisor. VMware, Proxmox, Hyper-V, or a mix, the air gap works the same way.
