The term electronic vaulting is used to describe the transfer of data by electronic means to a backup site, as opposed to the physical shipment of backup tapes or disks.
The viability of electronic vaulting depends upon the availability, cost, and bandwidth of communication lines. It should be remembered that a man on a bicycle with a set of magnetic tapes can easily deliver an average bandwidth of 300 MBits/sec over a five mile range.
