You’re no doubt aware that data must be kept safe, but how you do this has a major impact.
The first important factor is how often you can make a backup. This varies from once a day to maintaining a real-time copy, so only a few seconds of data are lost if a problem occurs. Here, you also have to think about where your data is stored; this might be taking a tape from the office, or safely storing all data in the cloud.
A second important factor is how quickly you can restore all your data after a “disaster” and allow everyone to get back to work.
