21 Best Cloud Backup Services Reviewed

Reviews of the best cloud backup services

Our editors independently research, test, and recommend the best products; you can learn more about our review process here. We may receive commissions on purchases made from our chosen links.

Cloud backup services work much like traditional backup software. With a cloud 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 the best cloud backup services. Quickly get answers to your cloud backup questions in our Online Backup FAQ.

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

Backblaze Review

Backblaze logo


What We Like
  • Unlimited storage

  • No file size limits

  • Relatively inexpensive

  • Can back up automatically

  • Supports previewing images before restoring them

  • Can keep old versions of files forever

  • Offline restore is an option

  • Includes mobile apps

What We Don't Like
  • Restoration is different for large files vs. small ones

  • The forever version history option costs extra

Backblaze is a favorite cloud backup service, mostly because everything about it is so simple—especially its pricing and software.

You can buy Backblaze for $7 /month, or less if you order it for a year or two at once.

We 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 also one of the least expensive unlimited backup plans that we've reviewed.

If you're concerned about backing up online being complicated or confusing, you're going to love Backblaze.

Carbonite Review

Carbonite logo


What We Like
  • Lets you back up an unlimited amount of data

  • Three plans to choose from

  • Files/folders can be added to the backup through Windows Explorer

  • Keeps everything backed up continuously

  • Every plan is free for 15 days

  • Mobile apps

What We Don't Like
  • No free online backup option

  • Doesn't back up large files by default (you have to select them manually)

  • File versioning is more limited than some other backup services

  • Only one plan supports offline restoration

  • You can't control the specific amount of bandwidth the program is allowed to use

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

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

All of Carbonite's Safe backup plans allow for an unlimited amount of data backup from one internal hard drive, are per-computer, and require at least a one-year prepayment.

Carbonite's lowest tier plan, Safe Basic, runs $6.00 /month ($71.99 /year). There are two higher tiers available as well, called Safe Plus and Safe Prime, and these run $9.34 /month ($111.99 /year) and $12.50 /month ($149.99 /year), respectively. Each tier is a bit cheaper if two or three years are paid up front. 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 cloud backup services with a BlackBerry app.

Carbonite also has business-class cloud backup plans.

Carbonite purchased Mozy, another online backup service, in 2018.

CrashPlan for Small Business Review

CrashPlan logo

CrashPlan logo

What We Like
  • Pricing is really easy to understand

  • You get unlimited file versioning

  • Zero file size limits

  • Really specific backup scheduling options

  • Can back up files from mapped drives

  • Works from mobile devices

What We Don't Like
  • You can't restore really large files via the web app

  • There isn't an offline backup or restore option

  • Doesn't support file sharing

CrashPlan has always been a favorite backup service. The plan pricing is simple to understand and the service itself is secure, quick, and not difficult to use.

There's one plan option with CrashPlan: $10 /month /computer. For example, if you wanted to back up from three computers, the price would be $30 /month; ten computers backed up to CrashPlan would be $100 /month, etc.

CrashPlan used to have a plan called CrashPlan Home, targeted at home users. However, even the CrashPlan for Small Business plan can be used at home; the pricing and features work the same.

SugarSync Review

SugarSync logo

SugarSync logo

What We Like
  • Pick from three online storage options

  • Every plan can back up files from an unlimited number of devices

  • Can keep files synced between your different devices

  • 30-day free trial for all plans

  • There's a limited free backup plan option

  • Keeps everything backed up nearly constantly

  • File sharing is supported

  • Can back up really large files through any web browser

  • Works on mobile devices, too

What We Don't Like
  • Doesn't support unlimited storage space

  • Keeps only five versions of every file

  • You can't back up specific files from the desktop program, only folders

  • Doesn't support backing up from mapped drives or external drives

  • No options for offline backup/restore

  • Can't back up every single folder on your computer

  • Files you're actively using can't be backed up

  • You can't upload folders through the web app

  • Doesn't let you pause backups

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 also syncs 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 /month.

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.

SpiderOak Review

SpiderOak logo


What We Like
  • Four storage plans are available

  • It's a zero-knowledge backup provider

  • Zero file size limits

  • Free trial lasts three weeks

  • You save when you buy a year at once

  • Lets you back up from an unlimited number of devices

  • Supports backup from external and mapped drives

  • Duplicate files don't take up extra space

  • Supports file sharing

  • Customizable backup schedules

  • Unlimited file versioning

  • Mobile apps run on iOS and Android

What We Don't Like
  • There isn't an unlimited storage option

  • No offline backup or restore options

  • It's a bit more expensive than other online backup services

  • Can't limit how fast the program downloads files to your computer

  • The mobile apps don't support backup

  • Can't set up idle backups

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

We love any company that puts the effort they did into their support, tutorial, and FAQ pages. It's been a long time since we'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 then select the 150 GB400 GB2 TB, or 5 TB plan for $6 /month, which cost $11 /month, $14 /month, or $29 /month, respectively. They also offer small 5–10 GB plans, but you have to pay for those by the year.

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 mentioned above will save you a little over the listed prices.

Zoolz Cloud Review

Zoolz logo


What We Like
  • Has zero file size limits

  • There's a free option available

  • Back up the whole drive or just specific files/folders

  • Supports backup from both mapped drives and external HDDs

  • Lots of scheduling options

What We Don't Like
  • Restoring is much slower than it is with other backup providers

  • There isn't an unlimited plan available

  • Limits file versioning to 10 per file

  • No mobile app

  • Vista and XP aren't supported

Zoolz Cloud 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 with Zoolz can take 3–12 hours to initiate.

This backup service lets you store all of your servers, internal drives, and external 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.

Several plans are offered by Zoolz Cloud, all of which can be purchased for a full year at once or on a month-to-month basis. Each supports unlimited users.

  • 1 TB: $9.99 /month
  • 2 TB: $19.99 /month
  • 5 TB: $49.99 /month
  • 10 TB: $99.99 /month
  • 20 TB: $149.99 /month
  • 50 TB: $449.99 /month

Those are priced by the month-to-month option. It's a bit cheaper if you decide to pay for a full year at once.

Zoolz used to offer Zoolz Home, a consumer-class plan, but it was announced in September 2020 that they'd be discontinuing it.

Livedrive Review

Livedrive logo

Livedrive logo

What We Like
  • Comes with unlimited online storage

  • There are two plans to pick from

  • Support for more computers can be added on an as-needed basis

  • Can back up continuously or between certain hours only

  • Works with mapped drives and external drives

  • Includes a built-in player/viewer for some files

  • Runs on mobile devices, too

What We Don't Like
  • There are lots of files that it won't back up

  • Doesn't support offline backup or restore

  • Lets you back up folders only, not specific files or entire hard drives

  • Not every plan supports file sharing

  • Deleted files are gone forever after 30 days

  • The web app can only restore files, not folders

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 one computer, whereas the Pro Suite can back up up to five computers.

Livedrive Backup runs $8.99 /month, and Pro Suite is $25 /month. All Livedrive online backup plans offer significant discounts if you prepay for one year.

Another plan offered by Livedrive is called Briefcase, which 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 make any of the Livedrive plans a good choice.

Acronis True Image

Acronis logo

Acronis logo

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

You can purchase their Essential backup software for $49.99 /year ($4.17 /month), it's pretty basic and doesn't specify how much backup storage is included.

The next tier is $89.99 /year ($7.50 /month) and you get 500 GB of online backup storage included. This is called the Advanced package.

Then there's the Premium package, which is $124.99 /year ($10.42 /month) with 1 TB of backup space. With this one, you can purchase more space for an additional price, anywhere from 2–5 TB.

The prices above are for backing up just one computer. You can instead pick the three or five computer options to back up more, but the price, of course, goes up as well.

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 logo

 IDrive logo

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

Some other features that make this one stand out among the competition include mapped drive support, disk imaging, and excellent mobile apps. There's also the extremely simple Basic Client you can opt for if you're not interested in all the extra settings in the full version.

The completely free plan gives you up to 5 GB of storage.

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

  • 5,000 GB for $79.50 /year
  • 10,000 GB for $99.50 /year

There's also a Team plan if you need more users (5–50), as well as business-class pricing and storage options up to 50 TB. For just photo backup, you might prefer the unlimited IDrive Photos.

All plans are offered in one-year and two-year prepayment forms, both of which are usually discounted for the first year. The prices you see above are non-discounted, one-year prices. Check their website for the most up-to-date pricing with discounts included.

We 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, it may be just what you're looking for in an online backup service.

Degoo logo

Degoo logo

The Degoo online backup service prides itself as a "top secret" cloud drive.

You can purchase Degoo Pro for $3 /month, which comes with 500 GB of storage for 10 devices. The yearly option ($29 /year) brings the monthly price down to $2.42 /month.

The Degoo Ultimate plan is a bit more at $10 /month, but you also get 10 TB of storage for an unlimited number of mobile and desktop devices. If you order a year at once for $99.99, the monthly price comes down to $8.33.

Degoo uses zero-knowledge encryption so that not even their employees can access the files in your account. Degoo's use of storage replication means that your files are backed up in chunks across different countries so that even if a data center is breached, there isn't enough information to access a whole file.

There's an option in the desktop program to keep files in your account even if you delete them from your computer. Sharing backed up files is supported, too.

It's free for the first 100 GB, with several opportunities to get 500 GB more (or 1 TB more with Degoo Ultimate). A free account doesn't include zero-knowledge encryption, does include ads, and can only back up files from one computer.

Degoo works on Windows and macOS, plus Android and iOS devices.

Norton's Security Software

Norton logo

NortonLifeLock Inc.

Norton, the makers of popular computer security and antivirus software, provides automatic online backup in its security software.

  • Norton AntiVirus Plus: 2 GB for $5.00 /month and one device
  • Norton 360 Deluxe: 50 GB for $8.75 /month for 5 devices
  • Norton 360 Premium: 100 GB for $10.42 /month and 10 devices
  • Norton 360 with LifeLock Select: 100 GB for $12.50 /month and 5 devices

Keep in mind that these backup services are usually heavily discounted for the first year. For example, 360 Deluxe is currently $80 off for the first year.

If online backup is all you need, you might not like Norton's software because each backup plan is just part of a larger suite of security tools. However, if you don't currently have an antivirus program on your computer, then getting one with backup included is a nice deal.

Data Deposit Box

Data Deposit Box logo

Data Deposit Box

Data Deposit Box (formerly known as KineticD) is an online backup provider that advertises "true month-to-month."

There are two backup options here, Personal and Business, and both start off at $20 /month for 200 GB. Exceeding that limit costs $0.10 for every additional 1 GB. NAS device users get 100 GB of free storage.

Unlimited devices and users are supported, so this is great for families where everyone needs backup space. You can use the same account on multiple computers so that everybody can share in the cloud storage.

There's a free 14-day trial option before you buy either plan.

Data Deposit Box sports all the excellent features of any online backup service that's in it for the long run, including an excellent history of data recovery, top-of-the-line security, file sharing, free customer service, and more.

ElephantDrive logo

ElephantDrive logo

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

The cheapest of these plans is $8.33 /month for 1 TB of backup space and support for 10 devices (and three sub accounts), if you pay for a whole year at once. You can add more space for the same price and storage as the month-to-month option—for example, another 1 TB for another $10 /month. The maximum storage plan you can pay for is 15 TB, but if you want more you can contact their support team.

Check the link below for the other plans you can choose from. There are also business online backup plans. The Enterprise option starts at 1 TB but can be turned into an unlimited plan if you choose that option.

One really cool feature with ElephantDrive's service is their "Web Explorer" that you can use to upload files via a web 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 logo

 Jungle Disk logo

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

The base price of $5 /month /user. There are no file size limits, network drive support is included, and you get AES-256 private key encryption. Additional storage is $0.15 /GB.

All the backed up data is compressed before it moves, which can save you around 30% on data usage.

Jungle Disk Server is their business-class plan and works similarly but at $10 /month instead.

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.

Amazon S3 charges per GB downloaded (e.g., when you restore data from your backup) and a very small fee per upload and download request. However, there isn't a charge if you go through Jungle Disk.

of 21


Memopal logo

Memopal logo

Memopal is an online backup service with support for a wide range of operating systems, both desktop and mobile.

There are two personal-level plans:

  • 3 GB for FREE
  • 500 GB for $79 /year

The 500 GB plan is for unlimited users, but there is an extra charge for each additional user. There's also a business plan that can support up to 50 users and that can be expanded beyond 500 GB.

Software or apps for Memopal are available for Windows, Mac, Linux, iPhone, iPad, Android, and BlackBerry.

of 21


ADrive logo

 ADrive logo

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."

All ADrive backup plans can be had at deeply discounted prices if you prepay for a longer time period, up to three years. For example, the 100 GB plan is just $1.67 /month if you buy it for three years at $60.

Multi-user business plans are also available.

of 21

Total Defense Online Backup

Total Defense logo

 Total Defense logo

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.

There are two ways to get online backup with Total Defense, and with both, you also get their Internet Security program:

  • Ultimate Internet Security: $99.99 /year with 25 GB of storage for 10 devices
  • Premium Internet Security: $59.99 /year with 10 GB of storage for 5 devices

You can buy either plan at two or three-year prepayments to bring the price down. For example, the 25 GB plan comes out to $8.33 /month for the one-year price, but if you pay for three years up front for $199.99 /year, the monthly equivalent drops to $5.55 /month.

of 21


OpenDrive logo

OpenDrive logo

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

In addition to the 5 GB free option, 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 one year at $99 to bring that down to $8.25 /month. You can add computers for $9.95 per computer, up to three extras for a total of four.

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 each day, 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.

The cheapest plan you can make here is $50 /year ($4.17 /month) for one user who needs 500 GB of storage and 25 GB of daily bandwidth.

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

of 21


MiMedia logo

MiMedia logo

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.

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

These are MiMedia's plans:

  • Starter: 10 GB for Free
  • Basic: 500 GB for $7.99 /month
  • Plus: 1 TB for $9.99 /month
  • Premium: 2 TB for $15.99 /month

Plans 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.

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

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

of 21


Jottacloud logo

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 one user to back up as much as 5 GB.

Personal and Home plans are available, too. The Personal plan provides unlimited backup space for $9.99 /month or as low as $8.25 /month with a one-year plan of $99.00. The Home plan includes anywhere from 1 TB to 10 TB of shared storage space for five family members, starting at $5.83 /month for the yearly option.

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. This one keeps the last five 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.

There's also a business plan for small and large companies that supports 1 TB of space for anywhere from two to an unlimited number of users.

Jottacloud's servers are located in Norway.

of 21




MyPCBackup is another online backup service with a really user-friendly web interface and a good selection of backup plans. Every user starts off with 1 GB of free storage.

  • Ultimate: 4 TB for $14.44 /month
  • Premium: 1 TB for $11.94 /month
  • Home/Pro: 250 GB for $10.69 /month

Each plan can be had for several dollars less per month if a full year (or even two) is paid up front. There's also a six-month option for all three plans. Since you can't add more than one device per plan, each device you want to back up requires a plan of its own.

Also available through the link below are add-on services, like a 5 GB sync folder, network drive support, bigger maximum file size limit, and other things, each of which come with an additional yearly payment.

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