Tony wants to implement off-site cold backups. What backup technology is MOST popularly used in this case?

Tape backups are the most popular solution for cold backups off-site. Cloud backups to a cold repository are increasingly common options and may be faster for some retrieval scenarios, but they are not listed as options. Storage area network (SAN) and network-attached storage (NAS) devices are not popularly used for cold backup and are instead used for online or nearline options. Disk backup could be used but remains less popular than tape for a true cold backup scenario.
