Chapter 9. Protecting Your Data > Project: Developing a Backup Policy

Project: Developing a Backup Policy

Every PC user should develop a backup policy—a defined method of backing up data regularly. The policy you develop depends on different factors. As you learned earlier in this chapter, you can choose from three different primary backup types: full, differential, and incremental. The decision to be made here is whether to use only full backups every time, or perform incremental or differential backups between full backups.

Deciding on which backups to perform can depend on many factors, such as the amount of data to be backed up, backup capacity and speed, and time constraints. If you have 2GB of data to back up, for example, and your tape drive can back up only 500MB per hour, the full backup will require four hours. But consider what you would do if you had only three hours to perform a backup during the week and six hours on the weekend. Obviously, in this case, you could not perform a full backup every night.
