摘要

Taking proper care of data is an unglamorous business. Although the capacity of modern hard disks is impressive, little thought goes into contingency plans. Here we explain different options for backing up your data, including tape, optical disc and network-based storage. We also look into methods of organising your data to be sure you're getting the best value from your backups. Taking backups is a form of insurance. Like any other insurance, you decide the coverage based on the risks, and a balance must be struck between the value of your data and the costs of backing up. Hard disk failures are often at the top of people's minds when considering backups, but in reality, hard disks fail relatively rarely, and human error or errant software are much more typical causes of lost data.
