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.
Best free storage options
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 systems, or "cloud" services as they're also known, use a virtual hard drive that's installed on your desktop and linked directly to your online space.
How do they work?
Once you've downloaded the storage service, you just open up the drive and copy and paste something on to it, like your holiday photos, for example. They'll then be uploaded to an online server and synced anywhere you've installed the software.
You can also share your photos and documents with friends and family (once they've installed the same service).
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.

It's also worth checking if you can get any free online storage from your broadband provider. BT and Virgin, for example, offer a decent amount of free storage for their customers. BT customers with the Unlimited Broadband Extra Package get 50GB thrown in while Virgin customers have access to the Virgin Media cloud and up to 50GB free storage.

Flickr (only for photos and videos)
1TB free - but you can't store other files
Owned by internet giant Yahoo, Flickr is probably the world's best-known photo-sharing site. It also allows you to store videos, but you can't save other files, so it doesn't really work as a full online storage facility.
Strengths? It's free to sign up and allows an enormous 1TB of storage space for photos and short videos. The site's designed to share and see others' photos, but if you want to keep some pics just for family and friends, you can set the privacy settings on each image to control who can see it.
What if you pay? You can double your storage space to 2TB for around £310/yr ($499/yr) - although you'll probably only need this if you're a professional or a true photography nut.
What's the security? Flickr uses 128-bit AES encryption.
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's more cost-effective to go for an option without any free storage.
Currys/PC World owned KnowHow offers 200GB of cloud storage for £15 a year and a huge 2,000GB (2TB) for £30 a year. Pay in advance for 5 years and the cost drops of £90 for 2TB.

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. 1TB of storage costs from £42. See Cheap Memory Cards.
Where 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.
