Top 20 Best Cloud Storage Providers – Reviews and Comparison of the Top Secure Solutions and Services. Find Unlimited Cloud Based Data Storage Services and Options


Cloud storage comes in all shapes and forms. Direct comparison between providers is often difficult because they focus on different aspects of the service. Often people will base their decision on the amount of free storage available. However, this is only one element that you might want to consider. Most solutions will include a degree of free storage, though if you are backing up photos and media this can run out quickly. It’s therefore worth looking ahead to see how much you will have to pay, and how much space it will get you. Aside from that, you should look at what operating systems are supported, and whether you will be able to back up and use files from more than one machine – if you are working on documents at home as well as in the office, for example, this may be important.

Sharing and syncing files may or may not be a priority for you, depending on whether you want one-off or live backups. Cloud security is also an important factor. There have been a number of high-profile hacks of cloud storage providers, and although all of them claim to have a good security policy, the reality is that only a handful give you real control over your data – look for a ‘zero knowledge’ policy, which means that they cannot view or hand over your files, even if they wanted to. The flipside of this is that you will bear greater responsibility for safeguarding your data, and there are sometimes usability implications (sharing and collaborating on files becomes harder if you also have to manage encryption keys, for example). There are very few companies that have managed to combine a good user interface with strong security and a competitive price, so you are likely to have to make a trade-off, depending on what criteria are most important to you.

Here is a rundown of 20 of the top providers and some of their respective benefits.


1. SugarSync Review Here

SugarSync’s starts at $9.99 per month for 100 GB or $74.99 per year (which represents a hefty reduction). For that, though, you get backup for unlimited machines, Mac or Windows, and there’s a 30-day free trial so you can make sure it’s worth it. You can add or edit a file on one device and it will instantly be available on another – and you can back up your existing folder structure (unlike with, say, DropBox), which makes things very convenient and straightforward.

With just a couple of clicks you can make sure that any folder is backed up in real time, so you can access them from other devices, anywhere – PC, Mac, iOS or Android. This means you can start work on a file at the office on one computer and finish it on the bus or at home on a tablet, seamlessly. It’s simple, it’s powerful and it’s still good value for money – with a 1,000GB package coming in at $55 per month, and custom plans available.

2. Carbonite  – Review Here

Starting at $4.92 a month or $59.99 a year, Carbonite is one of the most competitive cloud services when it comes to cost. They use the same approach for both personal and business cloud backup, targeting the home/small business user, though their business solutions are more expensive. (‘Pro’ gives you backup for unlimited workstations at $269.99 per year.) They have a series of products across this range, with both hybrid and cloud backup. They also offer 7-day support, from 8.30am to 9pm every day. There’s a 15-day free trial and their hybrid backup bare metal recovery service comes with a 30-day money back guarantee. Carbonite’s disaster recovery package – an all-in-one hybrid solution that gives you on-site data recovery and cloud backup, with 500GB of cloud space and a 1TB local drive – costs $1,199.99 per year.

3. IDrive – Automatically Applied 50% off Coupon

IDrive allows you 5GB of storage and the use of unlimited machines – a generous start. If you need more space, prices start at $4.95 a month for 150GB, or $49.50 per year. You won’t get a free trial, and it can only be used with Windows and Mac.

IDrive offer a ‘one stop shop’ solution that enables you to back up everything – PC, Mac, devices and even Facebook pictures into the same account. Business users can back up business computers, servers, Exchange, SQL, NAS and mobile devices.

As well as multiple device and social media backup, IDrive offers strong privacy options. Apart from 256-bit AES encryption, there’s a further option for a private key known only to you – putting your data beyond the reach of anyone else. There is also good version support – it will save 10 previous versions of files, so you can revert back to earlier documents if you need to.

IDrive also have an unusual way to kickstart your backup: they ship you a physical hard drive, which you copy your data to and send back to them, so you don’t have to worry about using your full bandwidth allowance for weeks on end to get a full copy in the cloud.

~FINAL-backblaze_logo_tagline4. BackBlaze

BackBlaze comes in at just $5 per month or $50 per year – a good saving on an already decent price. For that, you’ll get unlimited online backup. There’s also a 15-day free trial.

BackBlaze is designed differently to most cloud services. You simply download the software, install it, and then backup occurs automatically. There’s no need to select different files and folders. It just happens. BackBlaze hunts around your computer and finds photos, music, documents and other critical files. When your computer is not in use, it copies, compresses and encrypts them, before sending them to a secure data centre for safe keeping.

What’s particularly encouraging is the lack of any limits imposed. You can back up data to the cloud from an external hard drive, at no extra cost; there are also no limits to file size or bandwidth, which sets them apart from many others in the space. BackBlaze runs in the background on Windows or Mac computers. It’s not just secure, with strong encryption; it’s also easy to use, and files can still be accessed in the cloud from your mobile device using their app.


5. Dropbox

Perhaps the biggest and best-known name in cloud storage, Dropbox is many people’s first and last experience of a cloud provider. They are a highly popular choice for personal storage, thanks to their simple interface and competitive pricing. For $9.99 a month or $99.99 a year you get a massive 1,000GB of space, with 2GB for free. Dropbox is available for Windows, Mac and Linux users.

Dropbox syncs your files automatically and allows you to share them with your family and friends, even if they don’t have a Dropbox account. It’s supremely usable and intuitive, and files can be accessed from any device. You can share folders to collaborate on documents, though it’s not really suitable for business use – it’s designed for individuals and casual users, rather than enterprise. It’s a no-frills approach, and the privacy policy is more aligned with Google’s than, say, SpiderOak’s, but it’s a good entry-level choice if you need cloud backup.


6. Tresorit

Tresorit is a powerful cloud storage tool that comes with solid security and a ton of features that make it easy to use.

One of the biggest selling points of Tresorit is that it’s a zero-knowledge cloud provider. What this means is all the data is encrypted and only users have the key to decrypt them. Essentially, it also means Tresorit offers an end-to-end encryption.

When a user creates a folder (called a “tresor” here), it is encrypted, and remains the same until the user decrypts it. This is unique because most other cloud service providers encrypt a file at the time of creation, decrypt it when it reaches the cloud server, and encrypt it again while sharing. This process leave the data open to hackers and the NSA when it is in the cloud. With Tresorit, there are no such worries.

This obviously means no one, including the NSA, can access users’ data without their knowledge, thereby making Tresorit the perfect choice for any business or individual for whom security is a top priority.

Another salient aspect of Tresorit is its user-interface. The pastel colors, layouts, and the overall look and feel resembles a social media platform rather than a cloud storage app. This is a clever move by the company as most users are familiar with social media, and would have no problem using their UI. In fact, Tresorit even offers a tutorial, and rewards users who go through the tutorial with additional storage space.

Besides these two important features, Tresorit also offers other convenient features, such as:

  • Users can send their files to multiple people, and each of them can have different permissions.
  • Content is sent in the form of encrypted links, and these can be revoked by the user at any time.
  • It has an automatic versioning system.
  • Users can remotely delete content.
  • The list of permissions is comprehensive, and includes rights to print, copy-paste and forward.
  • Installation takes less than five minutes.
  • Easy file sharing and collaboration

All these unique features make Tresorit a preferred cloud platform today.



7. Google Drive

The giant of the web, Google provides a reliable and low-cost solution for cloud storage (and much more besides). You get 15GB of free storage, and if you need more it’s just $1.99 a month for 100GB, or $23.88 per year. You can use Google Drive on unlimited machines, but there’s no Linux option – just Windows and Mac.

The catch is privacy. Many companies are moving towards a model of charging little or nothing up-front, but monetising their customers by using their data for a variety of purposes, including advertising. Google are the masters at this, which is a double-edged sword. You get extremely cheap storage – and it’s hooked into all of their many other offerings, including email. Unfortunately, it’s not so good for keeping your information secure. Compared to the privacy-first app


crashplan8. CrashPlan

CrashPlan comes in at $5.99 a month or $59.99 a year, with a 30-day free trial. It’s available for Windows, Mac or Linux. Once you’ve set up your preferences, CrashPlan works away in the background, making sure you don’t lose any vital files – music, photos and docs are continuously and automatically backed up for you.

There are three levels of backup. You can select an external hard drive for free, so all your files are kept locally on a separate disk. Although that’s a start it obviously has its limitations, so there’s also the option to back up to other trusted computers in your network (e.g. family and friends). Lastly, there’s the cloud option, which is most secure: sign up to their cloud service and you’ll get unlimited online backup, with no caps on storage, bandwidth or limits on file types. CrashPlan uses enterprise quality hardware and military-grade encryption is standard. You can continue to access your files from any device you own.


9. Mozy

Mozy offers 2GB of free storage and then up to 50GB for paid plans, starting from $5.99 per month or $65.89 for a year. There are business, enterprise and personal options.

Mozy is well-known and trusted in the industry, so there are plenty of testimonials and reviews to show you what their strengths are – they’re used by over 6 million individuals and 100,000 businesses around the world, who entrust over 90 Petabytes of data to them. Their ‘set it and forget it’ option means you can schedule backup for a time (or times) of day that’s convenient – it’s customisable to suit you. There’s a strong emphasis on security, with double encryption (256-bit AES or 448-bit managed Blowfish key, plus transfer with an SSL-encrypted connection). Data centres are monitored 24/7, with temperature control, backup power, seismic bracing and other safeguards you won’t hear about from most other providers. They have multiple EU data centres, so that European data can be stored in Europe.



JustCloud is one of the best providers out there. They offer unlimited storage, with prices starting at just $4.49 per month or $53.88 per year, with a 14-day free trial. They offer a fast and secure service, with syncing across multiple different computers and devices. There are free mobile apps, and you can share files with friends easily. It’s a straightforward and automated service that aims to make hard drives obsolete, with a huge breadth of devices and operating systems supported.

Should you need it, there’s 24/7 support, so if you have a problem there will always be someone on hand to help. There’s also unlimited file versioning, which means every new version of a document is recorded so you won’t lose a file if you make a mistake – you can always revert to an old one. Files are encrypted with 256-bit secured socket layer encryption and stored in secure data centres, monitored round the clock.

11. Mega

Mega’s cloud packages start at EUR 9.99 per month for 500GB, or EUR 99.99 per year. You get 50GB of free storage, and it’s available for Windows, Mac and Linux. (There’s also a new ‘Lite’ plan for low use – 200GB storage and 1TB bandwidth for EUR 4.99 a month.) Mega has only been around since 2013, but it has carved out a good reputation for itself. It has a very strong ethos of data protection, and its approach is guided by the principle that ‘security by policy’ is grossly inadequate; only security by design is sufficient in a post-Snowden world. In other words, powerful end-to-end encryption, with Mega itself denied access to your data. However, this does not affect usability. Despite the fact that Mega ‘remains the only cloud storage provider with browser-based high-performance end-to-end encryption’, it’s unobtrusive, a combination which has attracted millions of customers.

12. SOS Online Backup

SOS is another great low-cost cloud solution, starting at just $5 per month for unlimited storage, or $59.99 a year. There’s a 14-day free trial and it’s available for Windows or Mac.

SOS boasts an ‘infinite backup forever’ approach, in which you have literally unlimited data, which will be kept in the cloud indefinitely. End-to-end encryption is always on, so your files are encrypted before they leave your computer. There’s also a powerful Android app to back up everything on your mobile devices. What’s more, you can restore lost files at any time, from any device. SOS’s UltraSafe approach employs user-created keys, which are never stored in the cloud – so you and only you can access your files. (However, this does mean that if you lose your keys, your data will be unrecoverable.) Data is stored on secure, monitored servers, which are backed up to different hardware every night.

13. SpiderOak

SpiderOak adopts a Zero Knowledge approach to privacy, their USP. Prices start at $7 per month for 30GB, or $84 a year; you can use it on unlimited machines and it’s available for Windows, Mac and Linux. Plans go up to 5TB, with 1TB just $12 a month. For that, as well as the impressive amount of space, you also get sole control of your data: nothing unencrypted is stored on their servers. It’s an approach that has been endorsed by Edward Snowden, who compares them (very favourably) with DropBox. SpiderOak’s policy is that privacy should come as standard, and that companies that don’t want to give it to you invariably stand to make money from your data. Despite the strong emphasis on encryption, it’s still a relatively flexible solution, with scalable services for groups and enterprise customers.

roach of other companies, which use local encryption, it’s an open book. If you don’t mind that, it’s a good option.

14. Norton

Norton is a big name in online security thanks to their antivirus and other products, and they’ve branched out into cloud storage too. There’s no free storage and no free trial period, but for $4.17 a month ($49.99 a year) you get 25GB and you can use it with up to 5 machines, Windows or Mac.

With their security background it won’t come as a surprise that they offer strong encryption. Important files are backed up automatically, and you can easily add more storage as you need it. It’s also straightforward to transfer files between computers, and retrieve backed up files from any machine via a secure, password-protected web page. Previous backups are held for 90 days, so if you need to revert to an older version in that time, they’re available. Files are automatically compressed at backup to save space.

15. SafeCopy

SafeCopy offers a lot of storage at a reasonable price. You get 3GB for free, after which it’s $4.17 a month ($50 a year) for up to 200GB. There’s a 30-day free trial, and you can use it from an unlimited number of machines (Windows and Mac). Files are protected with 448-military grade encryption, and most of the heavy lifting is done by SafeCopy’s own servers, so the CPU overhead is low. There’s unlimited versioning, you can backup multiple folders (unlike Dropbox, for example) and you can restore files from anywhere. If you delete a file on your computer, it remains on SafeCopy, unless you manually delete it too – so it’s a great way to avoid mistakes. It’s also easy to share files with friends and family. SafeCopy comes with support for 15 languages.

16. Livedrive

Livedrive provide unlimited storage for $8 a month or $48 a year. There’s a 14-day free trial, but no free storage allowance, and you can use it on only one machine. Windows and Mac are supported.

Livedrive is one of the fastest-growing cloud storage services. Their Briefcase option is a step up from the basic backup; it’s easy to set up and there are apps to enable you to see your files on any iOS, Android or Windows 8 device. You can sync files across different computers so you can work on them seamlessly from device to device, sharing documents and accessing them from the web. Space is generous, with a 2TB allocation as standard. Pro Suite gives you further functionality and an impressive 5TB of space.

Livedrive is also aimed at resellers who provide backup, cloud storage and sync products to their customers. There’s a flat fee per month for this, with no per-customer billing.


17. OpenDrive

OpenDrive offer unlimited space on unlimited machines from $9.95 per month or $99 per year, supporting Windows or Mac systems. You get 5GB of free storage. As well as desktop versions, there’s an Android app you can download to back up and share files quickly and easily from a tablet.

There’s round-the-clock live support for business users, and plenty of tools to make sharing files with other people easy. You can manage space and bandwidth, as well as the number of users, changing them whenever you need to. Files and folders of any size can be shared, and media files played directly from the cloud.

‘Hotlinking’ enables you to link to cloud-based files in emails and documents, and it’s easy to add people to shared folders. This does, of course, come at the expense of some data security.


18. altdrive

Altdrive offers no free storage and you can only use it on one machine, but there is a 30-day trial and it works with Mac, Windows and Linux (as well as the Solaris operating system). You can buy unlimited storage for $4.45 per month, or $44.50 a year.

Altdrive supports very large files – up to 4GB – making it an option for businesses that routinely deal with such documents. There’s a strong emphasis on security, which is one of the reasons it does not offer syncing or sharing of files (which are offered by platforms like Dropbox); they state that ‘we cannot recommend them for sensitive files because they have ongoing unresolved security issues.’

There’s somewhat of an emphasis on tech-savvy users, and they offer some services that others don’t – such as geolocating of stolen machines. File versioning is supported, and you can backup on demand or to a schedule.

19. Zoolz

Zoolz are a slightly more restrictive and expensive option than most of the other top solutions on the market. There is no free storage, you can use only one machine, and it’s Windows only. It’s $14.17 per month or $169.99 per year for unlimited GB.

Zoolz specialise in long-term storage, stating that they will keep your data in the cloud for a lifetime – and that other companies do not have this long-term outlook. Before documents are sent to their servers they are encrypted with 256-bit military-grade AES encryption. There are plenty of features such as scheduling and setting upload speed limits, and there’s a hybrid option if you want a second backup on a local server.

Although you can restore individual files or everything, should you need to, the process incurs a delay of 3-5 hours – something Zoolz state is to do with their long-term approach, without explaining why. This, along with the higher-than-usual cost, may put off some prospective customers.

20. ADrive

ADrive is a pretty flexible option, supporting Windows, Mac and Linux systems. You can use unlimited machines, and there’s a 50GB free starter option. After that, prices start at $6.95 per month or $69.95 a year.

You can access files from anywhere, and share or edit them online. There are good search tools, and folder upload for simplicity. Premium and business packages offer online collaboration, file history recovery, public file expiration and SSL encryption. However, premium/business packages also offer ‘No 3rd Party Advertisements’, which suggests the basic package will include ads – not something many people will want to sign up for. You can access your files from anywhere with an internet connection, though, and there are also Android and iOS apps to download, as well as desktop software.

    Please be aware that backup sync is not the same as backup store. Please be careful of these services as uninformed choices can lead to catastrophic disasters, especially if you are the type to look over or too lazy to read features.

    Backup sync are cloud providers that continually back up the files in your computer. Many of them (all of them above) keep only the latest version and delete the previous one. It is a disaster if you happened to have made a mistake and needed to restore the previous version. Google cloud is notorious for this.

    But the real disaster is when you thought you had backed up your files from your external drive, deleted those files from your external drive and reformatted the drive so you could sell or dispose of it, and then when these syncing clouds detect that your external drive is not connected to your computer anymore, they will treat those files as having been deleted and delete the backup in the cloud as well. Although backblaze is one of the cheapest providers here and is probably one of the more famous ones, it is notorious for deleting files if a backed up external drive is not detected/connected in 30 days. Although to remedy this one, they have launched the B2 which serves like the Amazon glacier or Google nearline, but 440% cheaper.

    If you have terrabytes and terrabytes of files needing to be backed up or stored in the cloud, which you infrequently access, the best one to choose from is probably Amazon’s cloud drive. It does not sync your files, except your photos, and provide unlimited storage. Plus the UI is also very friendly

      abosolutely well said!! these are “synchronisation” services…delete it locally and if you’re not careful, it’s gone on the server too! as yu say, B2 from Backblaze appears to be a real backup service.

      cloud storage or cloud synchronised storage?

    Im missing Ahsay in this top twenty. Ahsay has great advantages for our customers like SQL and Exchange support, in this top twenty i only see Idrive with SQL and Exchange support above (i didn’t read all specs on all websites of these providers). And even with Idrive then you need a business account which is much more costly. We at Cloud Back-up ( have SQL, Exchange, Hyper-V and VMware support in our basic account starting at € 12,95 a month, i don’t see why a business acount has to be that much more expensive. Of course, the software can be different for home of business users, but the storage isn’t i like to think…or is it?

    Here is a cloud provider missing from your list: is a cloud-based platform that enables users to store and share private information safely and securely under the next level of privacy encryption standards…Zero Knowledge. Moreover, it allows users to chat among their approved Haystack Connections without revealing their mobile numbers. The resulting combination delivers what has now become a part of our daily lives; storing and sharing files and chatting with others all in a single app, on one platform, putting the user in control of his or her privacy
