Answer: C - Electronic vaulting is popular with financial institutions and is an alternative to manual electronic backup solutions. Electronic vaulting makes copies of files as they are modified and periodically transmits them to an offsite backup site. The transmission does not happen in real time, but is carried out in batches. So a company can choose to have all files that have been changed sent to the backup facility every hour, day, week, or month. The information can be stored in an offsite facility and retrieved from that facility in a short time.
