Cloudwards Editor’s Choice: IDrive
IDrive is our top choice for the best online backup provider. It has many features and integrates attributes of cloud storage like file sharing. IDrive gives you the flexibility to choose what you back up, including individual files. You can also schedule backups for specific days or times and receive notifications. IDrive is an affordable option with some of the best per-terabyte prices available.
How to Choose the Best Online Backup Services
We evaluated the following services based on the key aspects that most consumers look for in a cloud backup provider. Cost and features are important considerations, as are security and privacy. File versioning is another factor, and we’ve identified the best option.
Keeping specific types of customers in mind, we evaluated cloud backup services for businesses and freelancers. For companies, we focused on administrator features, backup features and restoration. Freelancers need a reliable way to back up their data, along with tools to interact with clients.
We identified the best backup services for ease of use and those on a budget. A key criterion was finding a cloud backup solution that can quickly protect your data in fewer steps. In addition, since most backup providers aren’t free, we’ve included a budget-friendly option.
Cloud Backup vs Storage Features
Are you confused about the differences between cloud storage and cloud backup services? Both store your files in the cloud, but there are distinct features for cloud storage and cloud backup.
Cloud backup saves files and entire systems for the long-term, and it also provides ways to restore data after disasters. On the other hand, cloud storage prioritizes easy storage and access to files, which makes it better for collaboration needs.
If you need something with regular access and collaboration options, you should consider using a cloud storage solution. Overall, we consider Sync.com to be the best cloud storage option for most use cases. You can read more about its features and functionality in our Sync.com review.

IDrive takes the overall top spot as the best cloud backup service. Others on the list include pCloud as the best free cloud backup and CrashPlan as the best choice for versioning.
1. IDrive — Best Overall Cloud Backup Service
backup software combined with file syncing and sharing.
Pros:
- Backup & cloud storage tools
- Can back up multiple devices
- Zero-knowledge encryption
Cons:
- No unlimited storage
- Must activate zero-knowledge at signup
IDrive has many features for both online backup and cloud storage, making it something of a hybrid service. Its cloud backup features let you cover multiple devices — including network-attached storage (NAS) external hard drives — and some plans also offer servers. Scheduling is a breeze with its robust menu that lets you choose the day or time.
As long as you don’t enable private encryption, you can share files from your cloud drive folder much like you can with a cloud storage service. For increased protection, you can create a shareable link with a password or set a download limit. If you set up zero-knowledge encryption when you create your account, it will disable the sharing capabilities.
IDrive Hands-On Testing
For beginners, the sheer number of options and settings can feel overwhelming. However, it takes little time to get used to the workflow for backing up your data or sharing files with others.

Using the desktop app — available for Windows and Mac — is the only way to get the most out of your account, and it’s where you set up and manage your backups. There is also support for Linux, but it isn’t a true desktop app.

If you want zero-knowledge encryption with your account, you must enable it during account creation. If you don’t, there’s no way to go back and give your account private encryption.
IDrive Pricing & Value
IDrive has several options for paid plans. Currently, there is a free 10GB account. However, that’s being replaced with a 30-day free trial. Paid plans have choices for personal, team or business use, and all plans support multiple devices. We cover all the details in our IDrive pricing guide.

2. Backblaze — Best Affordable Online Backup Service With Unlimited Storage
Pros:
- Unlimited backup
- Affordable prices
- File-type backup
Cons:
- No NAS support
- Limited advanced features
Backblaze is one of the few cloud backup services that offers unlimited storage capacity. It also has a simplified interface, making it easy to use even for those newer to online backup services. Businesses can take advantage of its file versioning, as it does not impose size limits. Backblaze will keep versions of your files for 30 days.
If you are looking for more advanced features, Backblaze probably isn’t the answer. It doesn’t have image-based backups, nor can you back up servers. Additionally, Backblaze does not support network-attached storage devices. However, what Backblaze lacks in features it makes up for in other areas, such as speed.
Backblaze Hands-On Testing
There isn’t much to the desktop app that is required to conduct a backup. Backblaze will back up the entire contents of your computer with only the option to exclude folders or extensions. The scheduling options are limited to three choices: continuously, once per day, or manual. However, it is a very easy-to-use application.

Notes From the Lab: Backblaze Security Analysis
especially if you enable the private encryption key.
Backblaze uses a random 128-bit AES symmetric key for each backup session and incorporates SSL protocols to secure file transfers. Additionally, Backblaze comes with the option of adding a private encryption key. You can access this from the desktop app.
Backblaze Pricing & Value
You can start with a 15-day free trial with Backblaze, as it doesn’t require a credit card to create an account. Backblaze offers a monthly plan for $9, a yearly plan for $99 and a two-year plan for $189. For more information, check out our Backblaze Business review.

3. Carbonite — Best Easy-to-Use Online Backup
Pros:
- Clean desktop interface
- Unlimited storage
- Affordable pricing
Cons:
- Slow speeds
- Limited features
Carbonite does a nice job of quickly getting you up and running with an easy-to-use interface and minimal steps to begin a backup. Once you establish the initial backup, you can see the progress clearly, especially on the desktop app. A dashboard on the web interface provides a snapshot of your backups.
Once you back up your data, you can easily manage it from the web or desktop. Carbonite doesn’t have many features, which helps contribute to its ease of use. One notable exception is the lack of robust scheduling features available for Mac. However, you can create a schedule on a Windows computer with the Carbonite Safe Backup Pro plan.
Carbonite Hands-On Testing
The desktop apps, available on Windows or Mac, and the mobile apps for iOS and Android are the best ways to engage with your account. You need the desktop app to create a backup, as the web interface has limited capabilities. The fact that Macs are short on scheduling features is concerning, but you can still back up individual files.

option to enable two-factor authentication.
Carbonite uses AES 128-bit encryption to protect your data, which is less secure than AES 256-bit. Windows users can manage a private encryption key, which increases the security to AES 256-bit encryption. Doing so removes the ability to access your data on the web interface or mobile app.
Carbonite Pricing & Value
Carbonite doesn’t offer a free plan, but its business plans come with a free trial. The Basic personal plan costs $6 per month when billed annually, with options for a two- or three-year plan.

- Supports external drives
Cons:
- Slow speeds

Its backup frequency options are similar to those for version retention. You can determine how often CrashPlan monitors and updates your data, with a minimum of every 15 minutes. Scheduling is limited — your only options are to keep things constantly up to date or to pick specific days and times.
CrashPlan Hands-On Testing
CrashPlan is a challenging service to get up and running. Some tutorials and guides are available to help you take your first steps. However, there’s a lot to do before you can start backing up your data. The web interface is mostly informational, as you need the desktop app to establish and manage your backups.
