5 Best Online Cloud Backup Services to Keep Your Data Safe

Looking for a safe place to back up and store all your digital data? This post will help you get started. Here, we’ll look closely at five of the best online cloud backup services to check out where they shine and where they fall short.

What is cloud backup?

First, let’s get past the basics. Usually, we back up all our data to an external drive or local network. These local backups are great for quick restoration. What’s disappointing is that they suffer from the very same risks that your computer does – malware, hardware failure, accidental erasure, fire, theft and the like.

On the other hand, the best online cloud backup services copy your entire data over the internet to remote servers at diverse locations. You’ll be able to conveniently access these secure off-site backups at any time from any place and restore them easily in a click or two.

Of course, there’s no reason not to do both – local and cloud backup – and be doubly safe. 🔒

The initial backup of your data can be hugely time-consuming. But thereafter, all your files are backed up automatically. The best online cloud backup services also allow you to send a physical device containing all your data for initial upload, and this can reduce upload time drastically. In the same way, they also allow faster restoration via a physical device shipped to you.

After researching the topic for a while and experimenting with a number of services in the market, we’ve decided to feature the following platforms in the top five. Here’s a quick overview of the features offered and the most important parameters of these best online cloud backup services:

Five best cloud backup services

Now onto the details of each platform:

1. Backblaze (

Best online cloud backup services: #1 Backblaze

Backblaze offers a bunch of useful features, including unlimited cloud storage combined with fast and reliable online backups, all at an attractive price.

Platforms and ease of use: Backblaze supports backup from Mac as well as PCs. Setup is easy too, needing you to just enter a few details like email id and password.

Storage and backup frequency: There’s unlimited storage, but that only covers one computer per account. By default, backups are continuous, though you can also schedule backups.


What does backup include? All your data is automatically backed up excluding system files, program files, applications, empty folders or temporary web files. If you’ve got data on external drives, that’s backed up too. You can specify the folders you don’t want to back up. The Business Plan allows backup of data from a network (NAS) too.

Pricing: The Personal Backup Plan as well as the Business Backup Plan are available. The Personal Plans are affordable, starting at just $7 per month.

How secure is your backup? Backblaze include at-rest and in-transit encryption as well as a personal key option. Two-factor authentication adds an extra security layer.

Is it easy to restore? Restoration of files is only via the Backblaze website. This can get tedious, as files are not restored to their original locations. Instead, the files have to be downloaded to a zip file that’s limited to 500 GB. Optionally, they’ll ship a physical device to you should you need it.

Other important considerations:

  • Old file versions and deleted files are retained for 30 days
  • File sharing is possible only via B2, Backblaze’s cloud storage service.
  • No syncing option

In many ways, Backblaze is the easiest to set up and use among the best online cloud backup services – automatically backing up your files on installation.

2. iDrive (

Best online cloud backup services: #2 idrive

IDrive is fast and offers greater control over your backup process when compared to other cloud backup services.

Platforms and ease of use: It supports multiple platforms like Mac, PC, Linux as well as mobiles. A centralized console allows you to manage backups. This helps you view the account activities of all your connected computers. Moreover, you’ll be able to change settings across all of your devices from this dashboard.

Storage and backup frequency: All free account holders get 10 GB in the Basic Plan. That increases to 100 GB when you upgrade to the IDrive Mini Plan. Backups are continuous, but you can also schedule online backups.


What does backup include? iDrive backs up the entire drive including OS, settings, apps, files/folders, with content and structure intact. You can exclude selected files.

Pricing: Besides a Basic Free Plan, iDrive offers Mini, Personal, Team and Business Plan. Plans start at $2.95 per year for 100 GB of cloud storage, but what’s attractive is that it can be used by all your web-enabled devices. Moreover, older versions of your files do not count towards storage.

How secure is your backup? iDrive encrypts all your files in transit as well as in storage. Account holders also get a personal encryption key.

Is it easy to restore? Restoration is via a desktop app or browser. While iDrive doesn’t automatically restore files to their original location, it allows you to choose the location manually. It’s also possible to recover deleted files from Trash within 30 days.

Other important considerations:

  • Can send you a hard drive with your data once a year at no extra cost
  • IDrive smartphone apps let you back up limited data from both Android and iOS
  • No limit on retention of deleted files until you do an archive cleanup
  • Retains up to 30 versions of each file
  • Can back up to external hard drives, network storage
  • Can share files that are backed up

iDrive is a fine choice among the best cloud backup services if your storage requirement is below 2 TB and if long retention periods are important to you.

3. Carbonite (


Carbonite offers automatic and unlimited cloud backup. Its simple set-up-and-forget approach is probably the easiest among the best online cloud backup services here.

Platforms and ease of use: Not only can you view and manage your backups from the desktop application, you can also use any browser to access your files via a well designed web interface.

Storage and backup frequency: Carbonite offers unlimited storage for a single computer in its Basic Plan. Backups are continuous, but scheduled backups are also possible.

Pricing: There are 3 ‘Safe’ plans, and costs are per computer. The Safe Basic comes at $6 per month, billed annually ($72.00). At $24.00 per month, the Safe Plus Plan will include external drives, back up videos by default, as well as back up a complete system image of your computer locally. For $50.00 per month, you get courier recovery service under the Safe Prime Plan.

How secure is your backup? All data is encrypted. Extra security is by way of personal key encryption and two-factor authentication.

Is it easy to restore? Using a desktop app, you can choose to restore all or some of the files, as well as search based on file names. Files can be restored to a single folder or to their original location.

Other important considerations:

  • Mac version offers neither versioning nor a personal-key option
  • Carbonite color codes your file system, so you know the backup status of each file or folder
  • Backs up photos from any android or iPhone
  • Deleted files retained for 30 days
  • Can access backups via mobile apps

With Carbonite, you’ll be able to view all your files from a web interface or mobile app. There are many options for restoration as well – individual files, all your data, previous versions or deleted files.

4. Acronis True Image (


Acronis True Image captures an image of your complete data and backs it up. It packs a lot in the range of plans it offers – from cloud backup, mobile and social media backups to ransomware protection.

Pricing: Prices start at $49.99 per year for the Standard package. The Advanced pack comes at $54.99 per year.

Is it easy to restore? Acronis restores files to their original location automatically through a web-based console. If you wish, you can also back up to an external drive or to mapped network drives. The latest offer is a “survival kit”, which quickly creates a bootable file-restoration tool.

Other important considerations:

  • Manually clean backups, user-configurable versions and retention
  • No seeding or restoration via shipped drives
  • Windows users can sync across devices
  • Halts cryptomining software, conserving your computer resources

Other important considerations:

  • No restriction on file size or type
  • Lets you customize your versioning policy
  • You decide the retention period for deleted files

CrashPlan comes with a higher price tag than many of the other best cloud backup services, but the fact that you get unlimited storage is a huge benefit for big-volume data consumers.

What about Dropbox and other storage services?

While cloud storage and synchronization services like Dropbox are useful, they are just that – storage services where you can park your data. They do not automatically back up your computer’s content. On the contrary, the best online cloud backup services back up all your data continuously and / or at scheduled intervals.

What to look for in a cloud backup service?

If you’re looking for a cloud backup service, you’ll want to start by checking the availability of these features:

💻 Platform support
Most services offer support for Windows and Mac.
🔧 Easy setup and management
A set-it-and-forget approach is best.

🔁 Continuous back up

🔑 Encryption of data
Including personal encryption key.

📂 Backing up to and from external drives
So you can control what’s outside of your main device as well.
♻️ Retention of deleted files

🔼 Upload and restore using physical devices
This saves time and bandwidth.
👐 Syncing and sharing
You want to be able to sync and share with other devices and friends.
📱 Smartphone backup

This is a lot of requirements, and it might be difficult to find a service that checks off all of that. Therefore, it’s always best to prioritize and decide which of these features are the most important to you, and then make your pick based on that.
