That way, if the new version of the software contains any serious problems, you can easily roll back your system to its previous state.) Under no circumstances do I suggest backing up less frequently than once a month or more frequently than twice a day-the risk is too high in the former case and the aggravation too great in the latter. On the other hand, if you use your computer only occasionally, the schedule could become once a month for duplicates and once or twice a week for archives.

Thus, if you use your computer heavily every day, and often install new or updated software, you might opt for weekly updates of your duplicates and daily updates of your archives.

No single answer is right for everyone, but as a starting point, my rule of thumb is that duplicates should be updatedДЄs frequently as major changes to your system (such as installing Mac OS X updates or new versions of applications), and archives should be updated every day you make minor changes (receiving e-mail, modifying text documents, and so on). How often should you back up your computer? And if youвЂ™re making both duplicates and archives, how often should you update each? However, if you do not leave your computer on all the time, you will need to take special care to ensure that itвЂ™s on and ready when the backups are scheduled to run. This could be an argument for scheduling backups for when youвЂ™re not using the machine.

If, on the other hand, youвЂ™re backing up to a hard disk or network device that can stay connected all the time, this problem occurs less frequently, if at all.Дepending on the speed of your computer, which software you use, and how you configure it, you may find that your computer slows down significantly while backups are running. On the other hand, if you schedule backups to run when youвЂ™re not around, you must always think ahead and make sure the drive has the necessary media ready. Swapping media can be an intrusion into your normal routine (especially if that routine involves the frequent use of other discs in the drive you use for backups). For example, if youвЂ™re backing up to a recordable DVD, you must be prepared to insert a blank disc whenever the schedule runs.

One consideration in choosing a backup schedule is media management.

I think itвЂ™s fair to state this as a corollary to MurphyвЂ™s Law: вЂњThe likelihood of suffering data loss increases in direct proportion to the elapsed time since your last backup.вЂќ In other words, if youвЂ™re performing all your backups manually, the one day you forget (or run out of time) will be the day something goes wrong. And let me be quite clear:Д«ackups are the only kind that matter. I can say from personal experience that backups are far more likely to happen regularly if your backup software runs automatically on a schedule.

TodayвЂ™s installment looks at when to schedule backups, how many backups you need, and how to backup a small network. Part one, Joe Kissell covered the different approaches you can take for setting up a backup strategy featuring duplicates and archives.
