Which cloud-storage service is right for you?

Cloud storage gives you 24/7 access to your documents, photos, music, and you can access them wherever you are and on whatever device you’re using. It also makes sharing photos, videos, and documents easy. Even better, a number of services are free. Here’s the scoop on four of the biggest cloud services:

Apple iCloud: Best for Apple users. Apple iCloud is built into many Apple apps, including Keynote, Pages, and Numbers. You can start writing a to-do list in Notes on your iPad, for example, and finish it later on your iPhone. iCloud also syncs your e-mail, contacts, and calendar on whichever Apple gadget (or Windows PC) you’re using.

Other cool ways iCloud automatically syncs your stuff across all of your Apple devices: Snap a shot with your iPhone, and you’ll find it on your Mac. Buy a song on iTunes on your desktop, and it downloads to your iPod Touch. Bookmark a site on Safari on one device, and it updates your bookmarks list on all of your gadgets. 5GB of storage is free; you can add more starting at $20 a year for 10GB.

Dropbox: Best for sharing files. Store and sync documents, photos, videos, and other files on your computer, tablet, or smart phone, then invite others to download. Just be aware that your allotted free storage includes data others share with you, so clean out your folder periodically and ask people who have shared their folders with you to remove them from your account. 2GB is free; add 100GB for $99 a year.

Google Drive: Best for collaborating in real time. Two things distinguish Google Drive from iCloud and Dropbox; first, you get the tools you need to create presentations, documents, spreadsheets, and drawings right from Google Drive. And once you create a file, you can not only share it with someone else, but you can also work collaboratively on it. When you make a change, the person you’re sharing with sees it right away.

It works well for work but has handy personal uses, too. For example, you and your siblings can work together on an anniversary-party invite for your parents, even if you live miles apart. Whenever your device goes online, Google Drive automatically syncs the latest versions of all of your documents. 5GB is free; add 25GB for $2.50 a month.

Microsoft SkyDrive: Best for Windows fans. It’s a no-brainer for Microsoft users, but SkyDrive has another big upside: It’s the best deal of these services. You can collaborate on projects and edit documents with free online versions of Word, Excel, PowerPoint, and OneNote. SkyDrive works on computers using Windows 8 (including Surface tablets), 7, and Vista, and Mac OS X Lion. You get 7GB free; add 20GB for $10 a year.

Some final advice: Always be familiar with your chosen service’s policies. And never use a cloud service as the only storage for files you can’t afford to lose. Your best option for backing up everything on your computer is still an external hard drive.

Happy World Backup Day! Go Backup Your Stuff! Seriously.

Hard drive backups are like the socks of gifts you give yourself. They’re initially about as unexciting as gifts can get, only to become the best gift ever in a pinch. Got a meeting in 20 minutes and your normal sock reserve is empty? Thanks for the bag-o-socks, Uncle Steve! Your hard drive just exploded, taking the past 3 years of your digital life with it? Thanks for the backup, past-me!

Besides being the day that keeps the people who make Peeps in business, today also marks the Third Annual World Backup Day. World Backup Day is a tradition that started on reddit back in 2011, and has been rippling out through the rest of the tech-loving world ever since.

Making today’s Backup Day particularly special is the fact that it falls on Easter, which, if nothing else, means you get to use “BRB! Gotta go check my backups!” as a way to escape any awkward family conversations that pop up before the ham is done. Or you could be a cool guy and introduce your less tech-centric family members to the concept of backin’ up their bits.

Oh, and tomorrow is April Fool’s day. Probably not the safest day for data, you know?

So, how should you go about backing things up?

If you’re trying to keep it simple, just go buy/find a big ol’ external hard drive, plug it into your operating system’s built-in backup tool (Here’s a guide to Backup on Windows, or Time Machine on OS X), let it do its thing, and then stick the backup somewhere safe. If you can find somewhere off-site (like a trusted friend’s house), that’ll help you retain your data in case of fire or flood.

If you want to get fancy and push your backups online, a couple of the big backup guys are doing deals in honor of today’s techno-holiday. Crashplan dropped their annual price from $71 down to $42 for the day, and Backblaze is giving away 3-months free to all newcomers. If you’ve only got a handful of files that you need to keep backed up, Dropbox’s free 2GB plan is a solid option.

Hard drives are cheap. Lost data isn’t. Go, go, go!
