Mac: You already make sure to back up your computer (right?) but what about your Google accounts? If something happened to it, you might not have time to get to Takeout to download your data before it's too late. That's where CloudPull comes in -- it's an automatic backup tool for your Google account.
Most of us have Google accounts that we'd be lost without, and it's scary sometimes to think about how much information could be lost if someone got into our account, or Google, for some reason, decided to close it (and knowing Google, it's not like you'd have recourse if they did.) Your Gmail, YouTube videos, favourites, or playlists, files stored in Google Drive, photos in Google Photos, music at Google Play Music, your Google Play Store apps, your Android phone -- all of it gone in a flash. The least we can do is back it all up, and if you have a Mac, CloudPull is a solid solution.
It's not cheap -- it's actually $US25, but for your money you get a tool that automatically backs up your account every hour, and takes point-in-time snapshots of everything every 90 days. You can customise all of this, of course, and tell it to back up your account more frequently, less often, or at specific times of your choosing. Similarly, you can select or deselect Google services to back up as you see fit. Best of all, CloudPull fits right in with OS X, giving you seamless access to your backed up files right on your desktop.
You can download the app and try it out for free, but to unlock it and all of its features, you'll need to pony up for a registration key -- and it's well worth it, considering how much data you probably have in your Google account. Check it out at the link below.
