Rotate Backups Offsite

I recommended maintaining at least two sets of backup mediafor example, two hard drives, each with a partition for a duplicate and another to hold your archives. With two copies of your backups, you can keep one next to your computer, ready for the next day's backup, and another in a safe place offsite. That way, if disaster strikes your home or office and takes out one of your backups, you have another to fall back on. If you swap your backup sets weekly, you'll rest secure knowing that even in the worst possible case, you'll lose no more than one week's data.

Today, after your backup software updates your daily archive and weekly duplicate, make the switch. Take the most recently used media and move it to another building, such as a friend's house or your office (if your computer is at home). Then, bring back the media you stored there last week, and you'll be ready for a new round of backups. You might even agree to a swap arrangement with a friend: every week you trade hard drives, giving each of you an offsite location for your data while keeping it in trusted hands.
