Mac: If you're a Tumblr user, you probably noticed the massive 24-hour outage it endured this weekend, and you're probably having one of those "what if I'd lost everything" moments. Luckily, Tumblr has a backup app to save you from such distress.
We don't talk about Tumblr a ton around here, but the sheer mass of this week's outage probably left a lot of people thinking, not only about their Tumbelogs but other blogs and social networks in the process. Sometimes things go down, and while often it's only for a short while and your data doesn't get lost, it's important to be prepared for the worst. Tumblr Backup (or the older, web-based tumble-log Backup Jammy for you non-Mac users) is a good way to make sure you keep all of that data saved in easily viewable HTML format on your hard drive. It's a simple and self-explanatory app: just log in, tell it where you want to save your backup, and let it go to work. Note that it doesn't back up privabe tumbelogs, submissions, notes, feed-imported posts, or audio files from reblogged posts.
Tumblr Backup is a free download for Mac OS X. You can also backup tumblelogs with the web-based tumble-log Backup Jammy, if you prefer.
And, if you're not a Tumblr user but you've still been scared into a backup frenzy after this weekend's events, you'll definitely want to check out previously mentioned Backupify for backing up your other services.
