It can be a costly and emotional experience if you lose precious holiday snaps, important files and work. To make things easier and for peace of mind, use a free online storage service to back everything up.

This guide explains how online storage services work and how to make sure they're safe, then rounds up the best of the free services out there.

Always check for compatibility. Make sure that the software you're using is compatible with your existing set-up. No liability can be accepted for any problems caused from acting upon the info given.

What is online storage?

Online storage

Online storage systems, or "cloud" services as they're also known, alllow you to store digital media online by uploading it through your computer or mobile device. Though transferred and accessible at any time via the web, the data is actually physically held on mammoth servers owned by whoever provides the partcular service you use (Google, Microsoft etc).

How does it work?

Once you've downloaded and installed the relevant software, any files (such as photos, for example) that you move into the preselected 'backup' folder will automatically be uploaded and stored in the cloud – you can usually change the settings so that your data syncs to other devices too.

It's also possible to access your data via your browser by logging into your online storage account at the company's website. Additionally, most offer free mobile apps for uploading and downloading files.

Many services let you share your photos and documents with friends and family via special links too.

Are they safe?

The biggest issue with using cloud storage is data security, as you are relying on the service to keep your files and documents secure. If your account is hacked, your files are immediately available.

Cloud storage companies typically use encryption to keep your information safe and two-step verification to ensure the right person has access to the account.

Encryption scrambles your data so that anyone unauthorised is unable to use it. The strength of the encryption is at three levels, starting at 128-bit, rising to 192-bit and with 256-bit as the most secure. Two-step verification involves sending you a message and asking you to respond when you login or amend your account to check you have the authority to do so.

See below for our full help on how to keep your account secure.

How much do you need?

The level of storage you'll need depends on what you'll be using it for. If you typically only back-up documents and emails, then 5GB will be plenty for most. If you want to back-up photos, music or videos then you'll probably need more.

It's impossible to estimate exactly how many files you can store in a set allowance, since it very much depends on the resolution of your photos/videos and quality of your music files.

As a general rule of thumb, 10GB should allow for about 4,000 photos, 12.5 hours of HD video OR 2,500 songs.

Best free online storage services

There are a whole load of online storage services available, with many offering up to 15GB of free space. They're largely similar in what they do, although a few have special functions. There's no limit to the number you can use – sign up for them all and you can grab tens of GB for nowt.

For photo and personal video junkies, we've also got info on free specialist photo storage services. These don't let you store other types of files though, so if you want to do that too you're better off going with one of the general ones, some of which, eg Dropbox, also have photo backup functions built-in.

5GB or 50GB 'free' for BT b'band customers

BT Cloud

BT Cloud

All BT broadband customers – standard or Infinity – get some storage space with BT Cloud. Given that BT captures around a third of the UK's broadband market, that's a lot of customers with free storage to take advantage of (and many not know about it).

If you pay: If your free allowance isn't enough, you can pay £3/month for an extra 50GB, or £9/month for an extra 500GB. Compare this with others before paying up though.

Apps: iOS, Android, Windows Phone, OS X and Windows. Full details on how to set up BT Cloud.

Free online photo storage

The services we've listed below are specifically designed for storing photos and videos, so if that's all you're after then they should fit the bill. If you're storing other types of files, scroll back up the page.

Unlimited free photo storage

Google Photos

Google Photos

Whilst technically built in to Google Drive and accessible from within it, it's more convenient to go to Google Photos directly if you want to store just images and videos. It will also help organise your photos, and is full of nifty features for doing fun and useful things with them.

What you get for free: Unlimited storage of photos of 16 megapixels or less and videos of 1080p resolution or lower. Google Photos will compress files larger than this, if you want to keep the unlimited option.

If you pay: If you tend to take very high resolution photos or videos (such as 4K), then you store these on Google Photos, but they'll contribute to your free 15GB Google Drive allowance (which you can get more of, for a fee).

Apps: iOS, Android, OS X and Windows.

Anything else?

1TB free, for any resolution photos/videos



Owned by internet giant Yahoo, Flickr is probably the world's best-known photo-hosting site. More like a social network than a storage facility, its focus is on sorting and sharing your photos, though you can use it for just backing up if you so wish.

What you get for free: Anyone with a (free) Yahoo account gets 1TB of space. One benefit over Google Photos is there's no limit to the resolution of the images and videos you upload.

If you pay: There's no additional storage available – Flickr Pro, which costs $5.99/month (£4) or $49.99/year (£35), gives users advanced stats on their photos and ad-free browsing/sharing.

Apps: iOS, Android, Windows Phone (unofficial), Blackberry, OS X and Windows.

Cheapest paid-for storage

If you've got a fair number of photos, files and documents and want the convenience of storing them all in one place, you'll have to pay to get more space. Several companies offer an additional 20GB or 50GB, but if you are going to pay it may be more cost-effective to go for an option without any free storage at all.

For example, Currys/PC World-owned KnowHow offers 2TB for £30 a year (though it has other plans avilaable too, see below). Pay in advance for five years and the cost drops to £90 for 2TB.

It depends on your needs but generally speaking the best-value add-on is an extra 100GB from Google Drive, which costs $1.99 a month (£16.60/year, although the cost will change as it is charged in dollars).

Annual cost of online storage
Free storage 20GB 50GB 100GB 200GB 500GB 1TB 2TB
Google Drive 15GB     £16.70/yr ($23.88)     £84/yr ($119.88)


Box 10GB   £84/yr  
OneDrive 5GB   £23.88/yr     £59.99/yr1
Apple iCloud 5GB   £9.48/yr £29.88/yr £83.88/yr
Amazon Cloud Drive 5GB2 £6/yr £16/yr £32/yr £64/yr £160/yr £320/yr
Dropbox 2GB3       £79/yr
BT Cloud 5-50GB4  


Google Photos Unltd for photos
Flickr 1TB for photos
Knowhow None £15/yr £30/yr
Table correct as of 2 Feb 2016. Includes plans up to 2TB; Google Drive offers plans up to 30TB, Knowhow offers a 4TB Plan. (1) Includes subscription to Office 365 Personal. (2) Unlimited free photo storage for Prime customers. (3) Up to 16GB on top with referrals. (4) BT broadband customers only – allowance depends on contract, see how to check.

Remember though, you're signing up for an annual cost, so if you just want to back-up your data, consider buying a portable hard drive instead. The cheapest 1TB of storage we found at the time of writing costs about £40.

Keeping your online storage secure

Whether it's your pics, your financial information or just your favourite funny cat videos you are storing online, you need to take steps to keep your data safe.

Here are some tips to keep you, and your info, safe from the hackers:

  • Keep your password secure. Change your password regularly and don't use the same password across multiple websites. If hackers crack one password it's a pain, but if they access all your online accounts it can be a nightmare. As many sites use your email as a login ID, using the same password increases your security risk.
  • Don't use predictable passwords. Using family or pets' names or dates of birth is common, but hackers can access some of this data from public sources such as Facebook. Break up passwords by using ranDoM capiTal leTTers or numb3rs. Or for a truly random password, use a password generator.
  • Use a password manager. If you struggle to remember large numbers of passwords, use a password safe or password manager to store them securely online. All you have to do is remember a master password and retrieve the others as and when you need them.
  • Disable auto-uploads. If you are concerned about sensitive info or pics, turn off the auto-upload function on services such as Dropbox or iCloud. These services automatically save a backup version of your documents in the cloud but don't distinguish between everyday photos and files and the ones you really don't want getting into the wrong hands.
  • Keep antivirus software up-to-date. Hackers are constantly developing nasty new computer bugs so you need to ensure that you've got decent antivirus and antispyware software in place and that it's up to date. Find out more in our Free Antivirus Guide.
  • Avoid phishing emails to keep out the nasties. Viruses and malware often sneak in disguised as other attachments, so ensure that any files you are downloading and opening come from a reliable source. See Phishing Emails.
