A veterinary office uses a computer$-$based medical record management system that normally works well. However, one day a virus strikes all of the computers and they're shut down for repair. Because the office can't function without the computer system, the practice must cancel the rest of the day's appointments. Which of the following would have been most appropriate to do as a backup plan should the clinic's computers become temporarily unusable?

Retain the services of a consulting group that would bring in computers and personnel to run them.

Preload available laptops as backups with the proper software.

Create paper$-$based copies of all computer files.

Arrange for reciprocal rights to use another veterinary practice's computer system.
