Which of the following backup types will MOST likely have a third party hosting the backup data?

Tape backups typically involve physical media stored either on-site or off-site at a dedicated storage facility, which may or may not be a third party, but the hosting of the data infrastructure is usually internal or managed directly.

Local backups store data on devices physically located within the organization's premises, such as external hard drives or network-attached storage (NAS) devices, not with a third party.

Cloud backups involve storing copies of data on remote servers managed by a third-party cloud service provider. The cloud provider is responsible for the infrastructure, storage, and often the security of the backup data.

Disk backups, whether to internal disks, external drives, or NAS/SAN, generally imply direct control over the storage infrastructure by the organization, not hosting by a third party.
