Other backup options
We’ve detailed the main types of backup that are relevant today; there are others, such as backing up to DVD, using a rotating offsite tape system, and doing smart things with rsync to synchronize local and remote directories, but the ones we’ve talked about are the most useful to most people now.
A last word of advice
Hopefully, then, we’ve helped you adopt the right backup system for you—or at least, gotten you to plug a sixty-buck hard disk into your Mac for Time Machine—but be careful not to get lulled into a false sense of security. Backup can help mitigate against data loss, and the more backup systems you have running the less chance there is that you’ll lose your wedding pictures, your work documents, your homework. Things can still go wrong, though, so be vigilant, and if one of your backup systems (or your Mac) goes awry, fix and replace it as soon as you can to keep up your protection.
Which brings us to your last bit of advice: every so often, do a quick audit to make sure your backup systems are actually running and are backing up as they’re supposed to. Set a recurring reminder—weekly, monthly or quarterly, depending on how conscientious and/or paranoid you are!—to check your backups.
