22 Online Backup Services Reviewed

Reviews of the Best Online Backup Services

Online backup services work much like traditional backup software. With an online backup service, however, your important data is transmitted over the Internet and securely stored on a server in a professional data center.

The advantage of having your important data backed up off-site, away from your home or office, is that it's safe from theft, fire, and other local disasters.

Below are reviews of most online backup services. Quickly compare features among my six favorites in my Online Backup Comparison Chart, read my interviews with them in my Online Backup Q&A, and get answers to your online backup questions in my Online Backup FAQ.

I also keep updated lists of the best Free Online Backup Plans, Unlimited Online Backup Plans, Business Online Backup Services, and Free Backup Software if you're interested.

Note: Online backup services, sometimes called cloud backup services, regularly change pricing and plan details so let me know if anything needs to be updated.

Backblaze is my favorite online backup service, mostly because everything about it is so simple, especially its pricing and software.

I also like that there are no file size limits, meaning you can finally back up your 100 GB virtual machine files and 3-hour 4K videos!

Backblaze is $5 /month /computer and allows an unlimited amount of storage. The cost can get down to a monthly $3.96 with a two-year plan purchase. This makes Backblaze one of the least expensive unlimited backup plans that I've reviewed.

If you're concerned about backing up online being complicated or confusing, you're going to love Backblaze. For what it's worth, this is the cloud backup service I pay for and use on my computers. More »

CrashPlan is one of my favorite cloud backup services because of the excellent software, cost effective plans, and feature set.

CrashPlan's interface is excellent and the features abound including a web-based restore option, continuous backup, 448-bit encryption level (better than your bank), and the foundation of a proven and excellent backup software program.

CrashPlan Unlimited is $5.99 /month /computer and, as the plan name suggests, allows an unlimited amount of online storage.

CrashPlan Family Unlimited costs $13.99 /month and offers an unlimited amount of online storage for up to 10 computers, all under the same account.

All CrashPlan plans offer slight discounts if you pay for a year in advance. More »

Any exceptional backup service should be easy to use, automatic, reliable, and easy to restore from. Carbonite is all of these.

Many people rave about Carbonite's online backup plans - they've been popular options for a very long time. My experience has been similarly positive.

All of Carbonite's backup plans allow for an unlimited amount of data backup, are per-computer, and require at least a 1-year prepayment.

Carbonite's lowest tier plan, Personal Basic, runs $5.00 /month ($59.99 /year). There are two higher tiers available as well, called Personal Plus and Personal Prime, and run $8.33 /month ($99.99 /year) and $12.50 /month ($149.99 /year), respectively. Each tier is a bit cheaper if two or three years is paid upfront. Plus, they each have a few extras over the base service like external hard drive and mirror image support.

Carbonite has mobile apps available for iPhone and Android systems and is one of the few online backup services with a BlackBerry app.

Carbonite also has business-class cloud backup plans. In fact, it tops my Business Online Backup services list.

Note: Carbonite used to throttle bandwidth after backing up a certain amount of data but is no longer doing so for new customers. This change may still be rolling out to existing customers. More »

SOS Online Backup logo

SOS is a big player in the online backup world, and for good reason. It includes only one backup plan but lets you choose between eight different storage capacities, all of which offer unlimited versioning, external and network drive support, and tons of other features, all at fantastic prices.

All of these different storage options offer the same support for 5 computers, but the cheapest is 50 GB and is $3.75 /month if you pay for a whole year at once, while the largest, 10 TB, is $250 /month for a year.

Every plan also supports an unlimited number of iOS and Android devices. Follow the links below to see the specific prices for the 100 GB, 150 GB, 250 GB, 500 GB, 1 TB, and 5 TB prices.

Note: Unlike some other online backup plans, SOS does not continuously backup all of your data - it occurs once per hour at most. However, certain types of files can be backed up instantly via SOS's LiveProtect feature. I have more on this in my review. More »

SugarSync is different.... in a good way. It's actually much more than an online backup service.

While SugarSync does "traditional" online backup just as well or better than much of its competition, it can also sync files between all of your devices, gives you access to your backed up data from your smartphone, and much more.

SugarSync has three tiers of online backup service that are each available on a month-to-month purchase plan: 100 GB for $7.49 /month, 250 GB for $9.99 /month, and 500 GB for $18.95.

All three of SugarSync's cloud backup plans offer support for an unlimited number of devices meaning you can back up your smartphones, laptops, tablets, and desktop computers all on the same account without any extra fees!

If you want more than just an online repository for safety's sake, you will no doubt be very happy with SugarSync.

SugarSync also has a business class plan as well as larger plans that you'll have to get a quote for. More »

SpiderOak is one of the better choices overall among the online backup services out there, especially when it comes to security.

I love any company that puts the effort they did into their Support, tutorials, and FAQ pages. It's been a long time since I've seen this kind of attention to customer support.

Pricing is pretty straightforward at SpiderOak. Everyone starts out with a trial run account that lasts 21 days.

You can select the 100 GB250 GB1,000 GB, or 5,000 GB plan for $5 /month, $9 /month, $12 /month, or $25 /month, respectively.

If you're after a service run by a company that takes their lack of access to your files very seriously, you're going to love SpiderOak!

A one-year prepayment of any of the plans I mentioned above will save you a little over the listed prices. More »

Mozy's online backup service works in a similar way to other services - you download and configure a piece of software and the backup is handled automatically in the background.

To get started with Mozy, visit their website and sign up for an account. Download and install their software, tell it what files or types of files to back up, and then set it to automatically backup whenever you like.

MozyHome Free is, you guessed it, completely free and gives you up to 2 GB of storage on Mozy's servers.

MozyHome's pricing is tiered: $5.99 /month for 50 GB from one computer and $9.99 /month for 125 GB of storage from up to three computers. Deep discounts can be had for one or two-year prepayments.

Additional computers and each additional 20 GB of space can be had for an extra $2 per month, each.

Mozy used to offer an extremely popular unlimited backup plan but ended it in favor of its current tiered plan in early 2011. Mozy also seems to be changing focus, away from its consumer business and more toward its small business and enterprise offerings. More »

Zoolz is an online backup service with just about every limitation removed but with a small trade-off. While most online backup services allow pretty much instant restore, a restore will Zoolz can take 3 to 5 hours to initiate.

Zoolz lets you back up all of your internal, external, and even network drives. There are no file type or size limits and nothing is ever deleted. If you're looking for a backup for archival purposes, Zoolz might be a great choice.

Two consumer-class plans are offered by Zoolz, both of which must be paid by the year at once.

Zoolz Family provides 1,000 GB for $5.83 /month. The last option is Zoolz Heavy - 4,000 GB for $20.83 /month.

Zoolz also offers Zoolz Business, a business-class plan. More »

Livedrive is an online backup service that offers an interesting mix of backup plans, a cost effective way to add computers, and a really nice computer and mobile app interface.

Livedrive "Backup" and "Pro Suite" are the two backup plans you can purchase. They both offer unlimited online backup, but the "Backup" plan only supports backing up 1 computer, whereas the "Pro Suite" can backup up to 5 computers.

Livedrive "Backup" runs $8.00 /month, and "Pro Suite" is $25 /month. With either plan, more computers can be added for just $1.50 /month for each one.

All Livedrive online backup plans offer significant discounts if you prepay for one year.

Another plan offered by Livedrive is called "Briefcase," and is just an online storage plan that offers 2 TB of space - it doesn't back up your files like a regular backup plan. Other features are included, though, like file sharing, file editing, file syncing, and more. This comes in at $16 /month.

If you purchase the "Pro Suite" plan, you get 5 TB of the "Briefcase" plan included, plus its added features.

"Military grade" AES-256 encryption, an excellent interface, and competitive pricing makes any of the Livedrive plans a good choice. More »

Acronis True Image Cloud

Acronis, maker of the popular True Image Home backup software program, is also in the online backup business.

When you purchase the backup software, you also get 50 GB of cloud storage for one year included in that price, making it $39.99. However, you can add additional storage too:

  • 250 GB for $49.98 /year
  • 500 GB for $59.98 /year
  • 1 TB for $79.98 /year
  • 2 TB for $119.97 /year
  • 3 TB for $159.96 /year
  • 4 TB for $199.95 /year
  • 5 TB for $239.94 /year

These prices are if you purchase the storage for a year at once. However, it's a little cheaper to pay for 2 years. Discounts of up to 25% off the first year are sometimes offered.

Also, the prices above are for backing up just one computer. You can instead pick the three or five computer option to backup more computers, but the price, of course, goes up too.

A premium plan is available as well, which starts you off at 1 TB of cloud storage and include additional features not found in the standard plan.

Learn More About Acronis True Image Cloud

Among other options, you can also encrypt your files with a password, schedule the backup to run at a later time, and choose a specific country for the data center where the files will be stored.

IDrive

IDrive is similar in most ways to other online backup services. Maybe the best thing about IDrive is that it comes with a free offline backup option, something I haven't seen with any other service and should come in really (really) handy for large initial backups.

Some other features that make IDrive stand out among the competition include mapped drive support and excellent mobile apps.

IDrive Basic is completely free and gives you up to 5 GB of storage.

IDrive Pro Personal comes in two tiers and offers support for backup from an unlimited number of computers:

  • 1,000 GB for $69.50 /year
  • 10,000 GB for $499.50 /year

IDrive also has business-class pricing and storage options available, up to 12,500 GB for $2999.50 /month.

All plans are offered in one-year and two-year prepayment forms. Two year IDrive plans are half off for the first year, and one year plans are reduced by 25% for the first year.

Learn More About IDrive

I found the IDrive software to be no more or less intuitive than any other online backup services. However, if their unique features are high on your priority list, IDrive may be just what you're looking for in an online backup service.

Norton Online Backup

Norton Online Backup is just what you'd think: an online backup offering from Norton, the makers of popular antivirus and computer security software.

Norton Online Backup has only one plan which offers 25 GB of storage at a cost of $49.99 /year (about $4.17 /month). You can back up from 5 different computers with your one account.

Learn More About Norton Online Backup

If 25 GB is all you need and you love Norton software, then go for this. However, I found nothing particularly interesting about Norton Online Backup vs other more feature rich offerings on my list.

The ElephantDrive online backup service offers a couple easy to understand plans to choose from, of which is FREE if you just need 2 GB backed up.

The cheapest of these plans is $9.95 /month for 1 TB of backup space. You can add more for the same price and storage, like another 1 TB for another $9.95 /month.

Check the link below for the other plans you can choose from. ElephantDrive also offers business online backup plans.

Learn More About ElephantDrive

One really cool feature with ElephantDrive's service is their "Web Explorer" which you can use to upload files via the browser from wherever you may be. Many online backup services only allow backup from your approved devices and only via their proprietary software.

Jungle Disk

Jungle Disk is an online backup service provider that works a bit differently than most. Jungle Disk structures their pricing so you only pay for exactly what you use.

Jungle Disk has a base price of $4 /month + storage fees. There are no file size limits, network drive support is included, and you get AES-256 private key encryption.

Storage fees differ depending on the online storage provider you choose to use with Jungle Disk. Amazon S3 (US or EU) or Rackspace are your options, costing $0.125 /GB-Month or $0.15 /GB-month, respectively. In addition to this, you immediately get 10 GB of free storage when you sign up.

Amazon S3 also charges $0.12 /GB downloaded (e.g. when you restore data from your backup) and a very small fee per upload and download request.

Jungle Disk Server is their business-class plan and works similarly but at $5 /month instead of $4.

Learn More About Jungle Disk

If the static plans of other online backup services don't appeal to you, Jungle Disk's pay-for-what-you-use plans might be an excellent fit for you.

ADrive is an online backup service that sports some interesting features like WebDAV support, online document editing, and more.

There are dozens of online backup plans listed on ADrive's site, ranging from $2.50 /month for 100 GB of space to $250.00 /month for 10 TB (10,240 GB). You can request a quote if you need more space than that, even up to "unlimited."

Total Defense Online Backup

Total Defense Online Backup is another service that offers a number of popular features like an online and local backup with the same tool, file sharing, mobile access to all backed up data, unlimited versioning, and more.

Only one online backup plan is available from Total Defense: $59.99 /year for 25 GB of online backup space.

You can buy the same plan at two or three-year prepayments to bring the price all the way down from the equivalent of $5.00 /month (for one year) to around $3.00 /month (with the three year $119.99 /year option).

Learn More About Total Defense Online Backup

Total Defense doesn't specify how many computers they support on a single account but they do say "multiple" so I'm guessing that means at least a few, possibly unlimited.

OpenDrive

OpenDrive is yet another online backup service that I hear good things about. They allow streaming video and music, public folders, and lots more.

OpenDrive has one consumer-grade plan called Personal Unlimited. It costs $9.95 /month and offers an unlimited amount of storage space for your backed up files. Prepay for 1 year at $99 to bring that down to $8.25 /month. You can also add up to four additional computers for $29.85 more each month (or one computer for $9.95 extra).

You also have the option of a custom plan with OpenDrive. Choose the online backup space you need, how much bandwidth you expect to use, and the number of users that should have access to the backups. Most of you probably won't find a better deal using the custom plan, but you might if you have a small amount to back up.

Learn More About OpenDrive

OpenDrive also has a free plan, offering 5 GB of storage, but since this plan doesn't offer file versioning or any kind of encryption, I'd stick to Personal Unlimited if you're looking for a true cloud backup solution from this company.

MiMedia

MiMedia has four backup plans, but they're severely limited in what you can back up. The only supported files are images, videos, documents, and music files.

MiMedia is much different than the other backup services from this list because nearly all of them can upload many more file types, like EXE, ZIP, 7Z, ISO, and others.

These are all of MiMedia's plans:

  • MiMedia Free: 10 GB for Free
  • MiMedia Basic: 500 GB for $7.99 /month
  • MiMedia Plus: 1,000 GB for $9.99 /month
  • MiMedia Premium: 2,000 GB for $15.99 /month

MiMedia's can be purchased at a slight discount if you prepay for a year at once. For example, with the Basic plan, paying monthly for a year equates to $96, or you can buy a year at once with one payment of $85.

Learn More About MiMedia

MiMedia can be used on Windows, Mac, iOS, and Android.

Backing up with MiMedia is great if you only need to back up things like your photos and music. For support for a wider range of file types, I suggest using a different backup service from this list.

Jottacloud

© Jotta AS

Jottacloud is another online backup service with a free plan, as well as an unlimited one, plus support for Windows and Mac, as well as iOS and Android.

Jottacloud has one FREE plan, Jottacloud Free, that allows 5 GB of backup from an unlimited number of devices.

The Jottacloud Unlimited plan gives you unlimited backup space as you need, from an unlimited number of devices. It runs around $9.90 /month or as low as $8.25 /month with a one year plan.

File versioning works a bit differently with Jottacloud. Most online backup services keep old versions of files available for restore based on length of time, like 30-day, 60-day, even unlimited. Jottacloud, on the other hand, keeps the last 5 versions no matter the length of time.

Files you delete from your computer are kept in Jottacloud's Trash folder for 30 days, giving most of you plenty of time to restore that accidentally removed file.

Learn More About Jottacloud

Jottacloud's servers are located in Norway.

MyPCBackup

MyPCBackup is another online backup service with a really user-friendly web interface and a good selection of backup plans.

The MyPCBackup Ultimate plan offers 1 TB of online backup space for $14.44 /month. Two other limited plans are also available: MyPCBackup Premium which runs $11.94 /month for up to 250 GB of storage space and MyPCBackup Home which allows up to 75 GB of storage for $10.69 /month.

All MyPCBackup plans can be had for several dollars per month less if a full year is paid up front. There's also a 6-month option for all three plans. Since you can't add more than one device for a plan, each device you want to backup requires a plan of its own.

Learn More About MyPCBackup

Note: MyPCBackup is owned by Just Develop It (JDI), which also owns ZipCloud, JustCloud, Backup Genie, and StudyBackup, four additional online backup services with similar feature sets and pricing. I didn't feel right about profiling them individually in this list considering how incredibly similar they are.

Didn't See an Online Backup Service?

Please let me know if I missed an online backup service and you'd like to see me review and include it above.

Wondering why some popular online storage sites aren't listed here? See Why Aren't Dropbox, Google Drive, SkyDrive, Etc. In Your List? for more on that.
