Cloud backup services work much like traditional backup software, but your important data is transmitted over the internet and securely stored on a server in a professional data center.

The advantage of having your 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 all the best options. 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

  • Backs up automatically

  • Supports previewing images before restoring them

  • Can keep old versions of files forever

  • 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 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

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

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, per-computer, and require 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 must be paid upfront for one year (those prices above) or two or three years. They also occasionally run deals of up to 40% off. They give you a few extras with the base service, like backup for an external hard drive.

Carbonite also has business-class plans.

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

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.

CrashPlan for Small Business

CrashPlan logo

CrashPlan logo

What We Like
  • Pricing is really easy to understand

  • Multiple file versions

  • Zero file size limits

  • Really specific backup scheduling options

  • Can back up files from mapped drives

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

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.

SpiderOak One Review

SpiderOak logo


What We Like
  • Four storage plans are available

  • It's a "no 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

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

SpiderOak One 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. 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, $11 /month, $14 /month, or $29 /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 mentioned above will save you a little over the listed prices.

Zoolz Cloud Review

Zoolz logo


What We Like
  • Has zero file size limits

  • Free trial 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

  • Payments are made yearly; no month-to-month option

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. 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 are purchased for a full year at once. Each supports unlimited users.

  • 1 TB: $199.99 /year
  • 2 TB: $399.99 /year
  • 5 TB: $999.99 /year
  • 10 TB: $1999.99 /year
  • 20 TB: $3599.99 /year
  • 50 TB: $8999.99 /year

Zoolz used to offer Zoolz Home, a consumer-class plan, but it was discontinued in 2020.

Livedrive Review

Livedrive logo

Livedrive logo

What We Like
  • Comes with unlimited online storage

  • There are two backup plans to pick from

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

  • Works with mapped drives and external drives

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

  • Runs on mobile devices, too

  • Can back up continuously or between certain hours only

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

  • Not every plan supports file sharing

  • Deleted files are gone forever after 30 days

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 5,000 GB of cloud storage and the added Briefcase features.

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

Acronis Cyber Protect Home Office

Acronis logo

Acronis logo

What We Like
  • Decently priced

  • Doubles as antivirus protection

What We Don't Like
  • No month-to-month option

  • No unlimited option

  • Might be too much if all you want is online backup

Acronis, maker of the popular Cyber Protect Home Office backup software program (formerly called Acronis True Image), backs up your computer and keeps it secure.

The Advanced package is the lowest tier that includes cloud storage. It's $54.99 /year for 50 GB of backup space for one computer. If you need 500 GB, the price jumps up to $89.99 /year.

The other option is called Premium, and it's $124.99 /year 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 don't include first-year discounts and 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

What We Like
  • Physical backup and restore option

  • Back up an unlimited number of devices from one account

  • 30 previous file versions are retained

What We Don't Like
  • Not always dependable

IDrive is similar in most ways to other online backup services. Maybe the best thing about it is that there is 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 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 10 GB of storage.

IDrive Personal comes in a few tiers:

  • 100 GB for $2.95 /year for 1 computer
  • 500 GB for $9.95 /year for 1 computer
  • 5 TB for $79.50 /year for 1 computer
  • 10 TB for $99.50 /year for 1 computer
  • 20 TB for $199.50 /year for 1 computer
  • 50 TB for $499.50 /year for 1 computer

There's also a Team plan if you need more users, and business-class pricing and storage options up to 50 TB.

All plans are offered in one-year and two-year prepayment forms, both of which are usually discounted. 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 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

What We Like
  • Inexpensive compared to similar services

  • Supports zero-knowledge encryption

  • Upload files through the web app

  • Share files with non-users

What We Don't Like
  • Has trouble previewing images from the mobile app

  • Bulk downloading is for paid users only

Degoo prides itself as a "top secret" cloud drive.

You can purchase Pro for $3 /month, which comes with 500 GB of storage for 10 devices.

The Ultimate plan is a bit more at $10 /month, but you also get 5 TB of storage for an unlimited number of mobile and desktop devices. It's identical to Pro feature-wise, but also includes "photo storage maximizer."

Degoo uses zero-knowledge encryption so that not even their employees can access the files in your account. Its use of storage replication means 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. Sharing backed up files is supported, too.

It's free for the first 20 GB, with an opportunity to get 5 GB more. A free account doesn't include zero-knowledge encryption, does include ads, can only back up files from three computers, and will expire if you don't use it every 90 days.

Degoo works on Android, iPhone iOS, and web.

Norton's Security Software

Norton logo

NortonLifeLock Inc.

What We Like
  • Includes security tools

  • Heavy first-year discount

What We Don't Like
  • Isn't unique if you're attached to a different antivirus solution

  • Lots of differences between the plans can make deciding on one difficult

  • Odd range of storage capacity options

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

  • Norton AntiVirus Plus: 2 GB for $59.99 /year and one device
  • Norton Standard: 2 GB for $89.99 /year for three devices
  • Norton Deluxe: 50 GB for $109.99 /year and five devices
  • Norton Select + LifeLock: 250 GB for $179.99 /year and 10 devices

Keep in mind, these backup services are usually heavily discounted for the first year, sometimes as much as 80% off; the website lists all the current deals.

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.


ElephantDrive logo

ElephantDrive Inc.

What We Like
  • Password protected link sharing

  • Large max file size

  • Share files with non-users

What We Don't Like
  • No option for two-factor authentication

ElephantDrive offers a couple easy to understand plans to choose from.

The cheapest of these plans is $8.33 /month for 1,000 GB of backup space and support for three sub accounts, if you pay $100 for a whole year at once (the other option is $10 month-to-month).

You can add more space for the same price and storage as the month-to-month option—for example, 1 TB for $100 /year, 2 TB for $200 /year, etc. 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. The family plan maxes out at 50 TB, and there's an unlimited business plan.

One really cool feature is you can share a folder with your colleagues via a URL link, and the changes you collaboratively make automatically sync to each other's devices. Many online backup services only allow backup from your approved devices and only via their proprietary software.

Data Deposit Box

Data Deposit Box logo

Data Deposit Box

What We Like
  • File versioning is supported

  • Can enable 2-step verification

  • Disable backups during selected hours

  • Web-based management

What We Don't Like
  • No Linux app

Data Deposit Box is an online backup provider that charges month to month and offers a free 14-day trial before you buy.

The plan costs $.10/GB for what you use, with a minimum of $20 a month after your 14-day free trial. NAS device users get a 90-day free trial and 100 GB of perpetual free storage for all ASUSTOR NAS devices.

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.

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.


ADrive logo

 ADrive logo

What We Like
  • Cheaper options for 3-year prepayments

  • 60-day free trial (no payment info required)

  • Several file transfer methods are supported

  • Large, 16 GB max file uploads

  • More plans to pick from than other services

What We Don't Like
  • Bare bones, boring website design

ADrive is an online backup service that sports some interesting features, like WebDAV support, online document editing, file sharing with password protection and expiration, and more.

There are several Personal Premium plans listed on ADrive's site, ranging anywhere from $2.50 /month for 100 GB of space up to $250 /month for 10,000 GB, with several options in between. If you need more space than that, you can go up to "unlimited" by contacting their sales team.

These 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 that start out at 200 GB for 10 users for as low as $4.67 /month, and go up to 20 TB for 1,000 users for $700 /month (more can be had by contacting them).


Memopal logo

Memopal logo

What We Like
  • Has a completely free plan

  • Access backed up files from any computer

  • Share your files

  • Auto-arranges photos for easy access

  • Unlimited file versioning

What We Don't Like
  • Checkout page is priced in euros

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

There's a single, 500 GB personal-level plan with different prices depending on the number of users you want. You can add up to 10 users, with each new user adding an extra charge; for example:

  • 3 GB for FREE
  • 1 user for $79 /year
  • 5 users for $395 /year
  • 10 users for $790 /year

There's also a business plan that can support up to 50 users and that can be expanded beyond 500 GB. You can order from the U.S. and will be charged in USD when paying in PayPal. However, if you pay via a major credit card, the currency depends on the card's standard.

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

Total Defense Online Backup

Total Defense logo

 Total Defense logo

What We Like
  • Great if you also need internet security software

  • Cheaper if you pay for two or three years

  • Use on up to 10 devices

What We Don't Like
  • Must also install their security program

  • No app for Linux

  • Only three storage options

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, 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 five 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 upfront for $199.99, the monthly equivalent drops to $5.56.


OpenDrive logo

OpenDrive logo

What We Like
  • Unlimited storage space option

  • Customize the plan to your needs

  • Works on mobile and desktop devices

  • 2FA via your phone

  • Promote to earn free space

  • Share direct download links.

What We Don't Like
  • Can't bulk pause web uploads

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, there's 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. 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.


MiMedia logo

MiMedia logo

What We Like
  • Decent range of plan options

  • Quick signup with Facebook or Google

  • Import from other services like Dropbox, Facebook, Google, etc.

  • Good-sized free plan

  • Auto-organizes files by type (photos, videos, etc.)

  • Two-step authentication option

What We Don't Like
  • Limits the file types you can back up

  • Can't upload folders from the web app.

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.


Jottacloud logo

Jotta AS

What We Like
  • Unique file versioning method

  • Upload folders and files from the web app

  • Several storage options, including a free one

  • Includes Office Online

What We Don't Like
  • Will reduce upload speed after 5 TB of use on unlimited plan

  • No desktop app for Linux (only a command-line tool)

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

There's one FREE plan that allows one user to back up as much as 5 GB.

Personal and Home plans are available, too. Personal provides unlimited backup space for $9.90 /month or as low as $8.25 /month with a one-year plan of $99. Home includes anywhere from 1 TB to 10 TB of shared storage space for five family members, starting at $6.99 /month, or $5.83 /month for the $69.90 /year 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 the Trash folder for 30 days, giving 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.




What We Like
  • All plans are identical apart from storage space

  • Try it out with the 1 GB free plan

  • It's cheaper the more you pay up front

What We Don't Like
  • Features that are normally built-in, cost extra in this service

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 $28.88 /month
  • Premium: 1 TB for $23.88 /month
  • Home/Pro: 250 GB for $21.38 /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 ($15.95 /year), network drive and external hard drive support, hourly backup, and bigger maximum file size limit, each of which come with an additional monthly payment.

MyPCBackup is owned by Just Develop It (JDi), which also owns ZipCloud, Instant Computer Backup, JustCloud, Backup Genie, and 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.
