Most, if not all, companies keep backup data to ensure data recovery should their computer system suffer damage.

Storing that backup data away from the original data is a safeguard in case of fire, flood or malicious damage.

Not all companies have the physical structures, or can justify the cost, to store their tapes offsite themselves.

Offsite Vendors provide secure offsite storage and transport options to companies to store their tapes offsite to allow a quick recovery from a loss of data event.
