Network attached storage (NAS) is great if you have lots of data to store and want it to be accessible without a physical connection. However, NAS is just as vulnerable to physical damage as an external hard drive, and a fire or a flood will destroy all your data. To prevent this, you should use one of the five best NAS cloud backup services to keep a copy in remote storage.

Key Takeaways:

  • IDrive is a great backup for your NAS if you keep it connected to a desktop.
  • CloudBerry Backup is a backup manager that will let you connect your NAS to an IaaS provider.
  • Backblaze B2 is an IaaS provider that’s cheap and works well with many backup managers.
  • MEGA and Google Drive are traditional cloud storage services that can be used for a NAS backup.

If you’re up to the task and have the money to pay the upfront cost, network attached storage devices are a great way to store a local backup, your media files or work documents. The files will be accessible from any device that has the right credentials, and a NAS is usually faster than cloud storage.

However, you should still budget for a NAS backup on the cloud, because even the best devices set up in a RAID configuration can fail. Since it’s often impossible to recover lost data, setting up your backup as soon as possible is ideal, but first you’ll need to decide which online backup provider you should use.

        What Makes the Best NAS Cloud Backup Providers?

        Many of the best online backup providers don’t offer any way to back up a NAS device. Others, such as Carbonite (read our Carbonite review), can back up these devices, but it’s incredibly expensive to do so.

        Because of this, our main two criteria are the backup features for backing up a NAS and the price per gigabyte. However, we will also consider things like security and privacy, customer support, ease of use and transfer speeds.

        1. IDrive — A backup service that’s cheap, easy to use and works well with any NAS
        2. CloudBerry Backup — Versatile management tool for power users
        3. Backblaze B2 — Cheap IaaS storage with a long compatibility list
        4. MEGA — Solid cloud storage that works well with the right NAS box
        5. Google Drive — Great if you want to use a large, well-known company

        IDrive is our top provider. As a relatively cheap provider with cloud storage and online backup features, it’s no surprise to see it at the top of this list. However, it’s closely followed by CloudBerry Backup — a provider that focuses on giving users as much control as possible, and Backblaze B2 — a provider that’s incredibly easy to use without being too expensive. 

        In fourth and fifth places are MEGA and Google Drive. MEGA is a relatively simple solution for QNAP and Synology NAS devices that has great security, while Google Drive has some excellent features like integration with Google Workspace that works well if you also need a solid cloud storage service.

        The 5 Best Cloud Storage & Online Backup Providers for NAS Devices

        Between dedicated online backup providers, management software, and cloud storage services that are compatible with common NAS operating systems, there are plenty of options to pick from. Without further ado, here are the best cloud backups for NAS.

        1. IDrive

        idrive and dropbox idrive client
        IDrive lets you connect an external drive or NAS to your online backup.

        More information about IDrive:

        • Pricing: 10GB free, 5TB for $69.66 per year
        • Website:


        • Fast transfer speeds
        • Zero-knowledge encryption
        • Great cloud storage features


        • Requires a desktop connection

        IDrive is the best online backup provider overall, it makes sense that it also ranks in our top five services for NAS devices. The 5TB and 10TB personal plans include the ability to back up a NAS of any kind. You can also use the smartphone apps to back up mobile devices and access files that you’ve backed up.

        Disappointingly, you’ll have to connect your NAS to a desktop for a backup to run, as you have to include it in the backup set for your PC. This probably won’t affect anything if you regularly connect it long enough for a backup to run, but if you only mount your NAS for a few minutes at a time, the backup could easily become out of date.

        However, you’ll also be getting one of the fastest online backups and a great feature set with plenty of backup and cloud storage features — including the ability to sync and share files. There’s even zero-knowledge encryption, in case you’re worried about the security of your data in the cloud. 

        Hybrid Cloud Storage for NAS Devices

        One benefit of a NAS is how easy it can make sharing files between devices. Including IDrive makes it a hybrid solution, as you’ll have your files available on your local network and across the internet. 

        Not only is this great for protecting your backup, but it also means you can go into your backup from outside your network by simply connecting to your IDrive account. This means you’ll never be without your files, even if something stops you from connecting to your NAS back home.   

        idrive slider homepage
        IDrive offers great value for your money.

        One of the most impressive things about IDrive is the price. At just $69.66 per year for 5TB of storage with discounts often available for your first year, IDrive costs around $0.00116 per gigabyte per month. That’s cheaper than archive storage with Microsoft Azure (read our Microsoft Azure review), if you use all of your storage. 

        Whether you want a nice selection of features, great security, low prices or a service that’s easy to use, IDrive is great for almost anyone. Read our IDrive review to learn more, and be sure to check out the 30-day free trial to see if you like this service as much as we do. We also have a comprehensive IDrive alternatives guide.

        2. CloudBerry Backup

        cloudberry backup restore plan
        If you need to manage a group of backup plans, CloudBerry Backup is for you.

        More information about CloudBerry Backup:


        • Versatile management tools
        • Compatible with most IaaS providers
        • Zero-knowledge encryption
        • Can use cold storage 


        • No built-in storage
        • Difficult to use

        CloudBerry Backup is a little different from the other providers on this list, because it doesn’t actually give you any storage space. We’ll go into that later, but to start, we’ll look at what it does offer.

        As a cloud storage management service, CloudBerry Backup lets you connect to infrastructure as a service (IaaS) providers and gives you the tools to control your backup in ways that the service itself might not allow or make easy.

        This includes the ability to set schedules and separate your files into different storage plans. You can also manage unlimited devices — including external drives and NAS drives — with backup space across multiple cloud services.

        Storage With IaaS Providers

        CloudBerry Backup is compatible with pretty much every well-known cloud computing provider, and lots of lesser-known services. It also gives you access to features like zero-knowledge encryption when the provider you’re using offers it.

        You can even mix services. This means you can split your data into hot and cold storage, set up redundant backups across multiple providers or put your sensitive data into a more secure backup space while everything else is in faster or cheaper storage.

        cloudberry backup slider one
        CloudBerry Backup costs just $29.99 per year and gives you access to cheap IaaS storage. 

        CloudBerry charges a small one-time fee to get access to the tool. If you want a free alternative, read our Duplicati review, but as it is, CloudBerry is pretty fairly priced. You can also take advantage of prices below $0.01 per GB per month if you choose a cheaper service like Microsoft Azure’s “cool” and “archive” storage. 

        If you want to juggle multiple computers and IaaS providers to get the best mix of account security, cheap backup space and advanced features, read our CloudBerry Backup review for more information. Just remember that it’s not the easiest provider to get into, so test out the free version before committing.

        3. Backblaze B2

        Backblaze B2 is cheap, easy to use and compatible with most NAS operating systems. 

        More information about Backblaze B2:


        • Low per-GB cost
        • Fast courier backup system 
        • Decent compatibility list


        • Poor zero-knowledge integration
        • A little hard to use

        If you’re using a pre-built NAS or an operating system made for NAS, there’s usually a backup manager included. For example, you can back up a Synology NAS with its HyperBackup software. These are great, but you’ll need a service to actually store your data. That’s where Backblaze B2 comes in.

        Backblaze B2 isn’t as easy to use as the standard Backblaze client (read our Backblaze review), but it’s compatible with a wide selection of backup managers and often one of the easiest and cheapest options available. This means that it’s a good choice for most NAS setups, especially if you’re using a common OS like TrueNAS or a pre-built from a supported vendor.

        Backblaze B2 also comes with some nice security options, like two-factor authentication and zero-knowledge encryption — just be sure to enable them. The private encryption is somewhat annoying to use, as you have to choose it and enter the key manually every time you upload files. Standard server-side encryption is easier to enable, as it’s done per bucket.

        The Backblaze Fireball

        One advantage of using Backblaze B2 storage is that you can order the Backblaze Fireball. This is a 96TB external drive that you can connect to your NAS and import all of your data. Since it can transfer at up to 10 Gbps through an ethernet cable, your initial backup can be done in just hours. You can even back up multiple NAS devices without spending too much time.

        This much backup space comes at a cost. The $75 shipping fee, $550 30-day rent and $3,000 refundable deposit aren’t cheap. However, if you’re looking to back up your NAS after years of use and want to protect your data without uploads lasting weeks, this is a great option. It would take over 100 days to back up 96TB on a 80 Mbps connection, after all.

        You can also order 8TB hard drives with your data on it, if you want a fast download. This costs $189 per hard drive, but that money is refunded when you return the device. 

        At just $0.005 per GB per month, Backblaze B2 is one of the cheapest hot storage providers available. There is a $0.004 charge for 10,000 “class B” and 1,000 “class C” API calls once you’re past the free 2,500 daily limit, but these are pretty reasonable compared to other IaaS providers. 

        If you’ve already got some kind of backup manager and aren’t a power user looking for every feature and option possible, Backblaze B2 is cheap, easy to use and is compatible with a wide range of devices and operating systems. Read more in our Backblaze B2 review.

        As it only charges for what you use, Backblaze B2 is often the cheapest option.

        4. MEGA

        best nas backup mega compatibility
        MEGA has a short compatibility list, but it’s secure and has large plans.

        More information about MEGA:

        • Pricing: 20GB free; approximately $33 per month for 16TB 
        • Website:


        • Great security
        • Large, cheap plans


        • Very poor compatibility

        Although it’s only compatible with Synology and QNAP NAS drives right now, MEGA — or, more accurately, MEGA CMD — is still a great way to back up your storage. The larger plans are dirt cheap if you need the space, MEGA’s security is some of the best and you’ll get all the sharing and syncing features that it offers as a cloud storage service.

        We would like to see compatibility with more providers, particularly with common operating systems like TrueNAS. However, if you are using a Synology or QNAP device, it’s worth considering MEGA.

        MEGA’s Security

        If you want to keep your data secure, MEGA has long been one of the best providers. With zero-knowledge encryption using the 256-bit AES standard as the default setting, in theory only you can access your data. 

        However, we need to mention a 2022 report that found serious underlying issues with MEGA’s encryption process, but the company seems genuinely motivated to fix these issues, at least in the short-term.

        There’s also two-factor authentication and servers across Canada, New Zealand and the EU, which helps protect your data from natural disasters. With MEGA, the security and privacy protections are great at keeping your files safe.

        mega cta
        MEGA is great if you need lots of space and still want some cloud storage features.

        At the low end, MEGA isn’t the cheapest. At just over $11 per month for 2TB, it’s more expensive than both IDrive and Backblaze B2. However, the largest 16TB plan is around $33 per month, which is cheaper than some cold storage, if you use the backup space.

        Overall, MEGA CMD’s compatibility is still limited to just two companies’ devices. However, if you have one of these devices and want a large amount of cheap storage space that comes with plenty of security, read our MEGA review to see how this provider can do for you. You can also give its 20GB free plan a try.

        • 20GB
        Pro I
        • File transfer: 2TB (Monthly plan) 24TB (yearly plan)
        • 2TB
        Pro II
        • File transfer: (monthly plan) 96TB (yearly plan)
        • 8TB
        More plans
        Pro III
        • File transfer: 16TB (monthly plan) 192TB (yearly plan)
        • 16TB
        • Price per user (minimum 3) 3TB Transfer quota
        • 100TB

        5. Google Drive

        share files online google drive
        Google Drive is well-suited for a NAS backup if you want to go with a larger company.

        More information about Google Drive:


        • Great compatibility
        • Large, reliable company
        • Extra productivity tools


        • Poor privacy & security
        • Limited control over backups

        All three of the big cloud storage providers — Google Drive, OneDrive and Dropbox — are great options for backing up your NAS drive. Of these three, Google Drive is best suited to a NAS backup, thanks to its larger plans.

        With any of the big three providers, you’ll have to deal with security concerns and limited feature sets. However, they also have great customer support and solid mobile apps, so it’s easy to back up Android mobile devices with Google Drive. 

        Integration With Google, Microsoft and More

        Perhaps the biggest benefit of using Google Drive is the fact that any storage you aren’t using for your NAS drive can be used as cloud storage, and that cloud storage space can integrate with a wide selection of apps.

        You can use Google Workspace with Google Drive, Microsoft Office 365 with OneDrive or either one with Dropbox. 

        This makes it especially useful for small business users, who might need a simple automatic backup for their NAS, a way to share files with other devices and integration with the other office software they use. Big providers like Google Drive can do it all for one subscription.  

        google drive homepage
        Google Drive has 10TB, 20TB and 30TB plans, which is great for a large NAS or multiple devices. 

        In addition to 15GB free, Google Drive offers some smaller 100GB and 200GB plans for $1.99 and $2.99 per month, respectively. However, premium users have access to larger storage plans. 

        At $49.99 per month for 10TB — around $0.005 per GB per month — Google Drive is a fairly cheap option. You can get cheaper, but if the plans line up with what you need, they won’t break the bank.

        There are downsides to dealing with a big company — particularly around privacy and data collection. However, if you need to protect your data and want a trusted, proven provider that’s easy to use, comes with some nice features and isn’t too expensive, read our Google Drive review to learn more.

        • Free plan
        • 15GB
        Standard 200GB
        • *The plan is "hidden." To find the 200GB plan, you need to be subscribed to one of the other plans, upgrade or downgrade to the 200GB through your account's settings.

        Final Thoughts

        Whether you prefer the option of cloud storage features or you want a dedicated backup service, there are plenty of ways to back up NAS to cloud storage. You can use a larger provider for long-term reliability, a smaller service for a unique feature or dedicated management software to mix and match other services.

        Regardless of what you choose, it’s important to keep backups of your data, or you risk losing it all. If you want to find out more about how to backup your NAS or which home NAS device is the best, then be sure to read our other articles.

        Do you have a NAS at home? Have you backed it up to the cloud? Did you use any of these services? Let us know in the comments below. Thank you for reading. 


        • There isn’t a one-size-fits-all backup solution, but we think IDrive gets pretty close to being the best service for most users.

        • NAS is a fantastic way to back up your files, especially if your file system is too large for stand-alone external drives. However, it will be vulnerable to failure and physical damage, so keeping a second cloud backup is still a good idea.

        • A Synology NAS will come with a piece of software called HyperBackup, which will let you backup your NAS to most common online backup and cloud storage services.

        • If you can find a good backup manager (such as CloudBerry Backup) that’s compatible with your device, you can back up any NAS with any cloud service.
