Best Free Online Backup Sites



Do you know when the absolute worst time to think about backups is? It’s the moment when the tech support guy tells you your hard drive has died and your data is lost.

One error that the free online backups will not help is recovery of a file a split second after you delete that important presentation or cherished photo. Most free services do not save deleted files but write over the old file.

The free online backup services will save your files off-site to the cloud. If your hard drive crashes your files are not lost. Your first line of defense should be an external hard drive to back up your hard drive or a jump drive for your documents.

An online backup provides 24/7 access to your files from any Internet connected computer, smartphone, or tablet style device. Data storage in the cloud is one of the quickest means to data archiving and recovery.

The requirements to judge the online backup are listed below:

 In a hurry? Go straight to the Quick Selection Guide



There are a number of products and vendors that promise you online data storage and backup. Here are my recommendations:

#1  IDrive (

IDrive's parent company IBackup has been in business since 1999 and therefore meets the long term reliability requirement. The service has 5 GB of free storage. While not a lot by today's standard it is better than 2 GB. IDrive does provide pre file transfer encryption. You provide the private key which will be known only to you. This will secure your files from being read by others without your permission.

IDrive has both scheduled and continuous backup. The default is scheduled backup. IDrive also has versioning. In this way if you accidentally delete a file, it can be retrieved.

Your files can be stored in any place on your hard drive. This allows you to keep your current file structure. It will not be necessary to move your file to a special folder for backup.

#2 Google Drive (

I just noticed Google drive now has 15 GB of online storage.  It is still not encrypted and you still have to put all your files in the Google Drive folder on your PC.  Google is an established company 15 GB is a large amount of storage.

I have moved Google Drive to #2 because it has 15 GB of storage available.  I have tested it and confirmed there are 15 GB..

Google drive has the follow good features.

  • First, it available storage is a large 15 GB.  
  • Second is the stability of the provider.  Google is going to be around for a long time and cloud storage is a key company service.
  • Third, it is easy to use.  Just go to your Google account ( assuming you have one), and down load the software.  
  • Finally you documents are automatically synchronized.

 Google Drive has two negatives: no security and files locations.

  • Your file are not encrypted locally before being uploaded to the "cloud".  Do not store files that you do not want others are to be able to read. While it is not open to anyone on the Internet who doesn't have the password, law enforcement agencies can obtain copies of your files without your knowledge.
  • Another negative is your files have to be stored in the Google Drive folder.  At first I thought this would be a problem, but after using the service there is not issue using the Google Drive folder for your files.

#3  OneDrive [Previously known as SkyDrive] (

Microsoft has changed OneDrive. It is now 7 GB if you are a new subscriber to the service. If you are an old subscriber and had 25 GB of storage you get to keep your 25 GB.

I dropped OneDrive's ranking because of its reduced storage space, no encryption and the annoying OneDrive folder you have to use. It is built into Windows 8 and the service is expected to be around for a long time as it's provided by Microsoft.

OneDrive's storage size is 7 GB. This is not very large by today standards. OneDrive originally was 25 GB. A new user can't get 25 GB free anymore. If you have an old Hotmail account you may have 25 GB.

OneDrive is easy to use. Once installed just copy or move the files you want to backup to the special OneDrive folder. Only files in the OneDrive folder will be stored online. It may be less convenient for you but the advantage of this approach is that you know exactly which files are being stored online.

You also have control over whether files are only stored online rather than on your local Windows device (PC, tablet, phone). Many users use OneDrive to synchronize files between two or more Windows devices. On each individual device you can specify whether a particular folder is stored offline (on the local drive) or online-only on OneDrive. If you store a large folder with several GBs of data on OneDrive then other devices that synchronize with that account will usually have online access so you will have to change it to offline to get a copy of the files.

One of OneDrive's weaknesses is the lack of encryption which means that you should not put files on OneDrive that you don't want other people to ever see. While it is not open to anyone on the Internet who doesn't have the password, law enforcement agencies can obtain copies of your files without your knowledge.

A combination of back-up solutions may be the best strategy. Use OneDrive for your photos and non critical documents like kids homework, your non-financial files, and family pictures. Then use Spideroak or IDrive for your taxes and financial files.

#4  Dropbox (

It offers 2GB free storage to start while multiple paid options are also available. Dropbox offers file syncing between the PC / Mac / Linux and the cloud. Load the desktop client or upload through the web interface and begin adding folders to the Dropbox folder. Once in the folder, Dropbox synchs the file between the PC and the cloud and any other devices that you have enabled with Dropbox including mobile and tablets. Quick, light and in the background, Dropbox is a must try and is my preferred Online Backup Solution. One drawback to Dropbox is a folder named "Dropbox" which has to be created, then all the folders and files have to be moved to the "Dropbox" folder.

#5  Mozy (

Like most of the online backup providers, Mozy offers 2 GB for free and the option to add more through paid services. Mozy comes with PC and MAC clients, schedule backups and even file encryption. The encryption capabilities provide some peace of mind to those looking for an Online Backup Solution but concerned about privacy.

#6  ADrive (

This site has been tested for the past month. It meets one of three off-line backup requirements. The storage size is very large at 50 GB. The down side is that it does not sync files. Longevity of the free service needs to be proven.


Other Thoughts

While 2 GB seems to be about the standard when this section first started. Now it is hardly enough. 2GB is roughly equivalent to 250,000 text emails, or 300 songs, or 250 pictures. We all have more the 250 pictures and will run out of space using only a 2 GB of storage.

Since this web site is all about free software, etc., I suggest using two online backup services. Use the sites with pre file transfer encryption for your important documents such as tax returns, then use OneDrive for photos. OneDrive has 7 GB. If you were lucky enough to have had OneDrive before they changed their service, you may have 25 GB of storage.

Besides the storage capacity, the ability to quickly get your data and long term service are other key factors to consider. Some of the above recommendations do not have proven track records but well known companies are likely able to provide long term service for you. Your data should be available and controllable by you. Being able to move your data from one provider to another or even duplicate it amongst providers for redundant backups are also key considerations when choosing a cloud storage solution. The first four suggestions above offer quick accessibility and easy exporting of the data so that you can take to another provider should the need occur.

Finally, regardless of the method or type of backup, whether online, disk to disk, imaging, CD / DVD copying, or floppies (hopefully not!), having a recent backup of your data will ensure that you never have to face that dreaded split second after your data gets ruined.

Dropped From The List

  • Windows Live Mesh: Microsoft dropped it in favor of OneDrive exclusively.
  • Bee Cloud is ceasing operation in March 2012.
  • Gmail, Hotmail and Yahoo mail have been dropped from the list. These are not really back up systems.
  • CX:, The terms of service has changed, therefore it is no longer free.  Existing users can keep their free account with certain condition, but new users have a 15/30 day trials.

NB: Do you have a great free online backup solution? If so, then tell us about it in the comments section.

From my testing Google Docs for this site I have determined Google Docs is not a online back-up system. Several of my MS Office files were uploaded to Google Docs they were changed from Office format to Google Docs format. kyengineer Best Free Online Backup Sites Editor
The upload settings allow you to uncheck "Convert Uploaded files to Google Docs format" to keep the original format but then you can't edit it on Google Drive without the conversion.
Google Docs does not seem to be a backup site, it's just for collaboration and sharing of documents. However, I think Google Docs is a part of Google Drive? Not very clear to me when I visited the Google Docs site.
Google Docs is a part of Google Drive, which can be used for backup.
Thanks for comments.

Using Dropbox for over a year, and I can say it's awesome, as well as Google Drive and Sky Drive. Even though I didn't keep a local backup of these folders, the files automatically syncs back to my desktop after the fresh install of Windows 7 X64! Amazing, elliminated about 374.4MB of backup!
My recommendation: Try using multiple services, they can be very helpful!

Hey, thanks for the comment. I agree, using multiply sites is a good way of backing up you files off site. I have not tried Google Drive yet. Does it work the like Skydrive?

Yes, Google Drive behaves like Dropbox and Sky Drive, where you put all files you want to back up in the Google Drive folder, and it gives you 5GB for free. I don't use it that much though, mainly used it as a mirror backup copy of my Dropbox.

i registered an account just to comment...
Just wondering if was ever considered, and if so, why was it not on the list?
I got 50GB from the Android promo they had earlier..

Thanks for the comment. How do you get the Android promo?

For a couple of years I been using Wuala. I fully recommend their online backup and sync. Simple to use, and it works every time. The biggest benefit is that you can sync to any file or folder. Perfect! But I am getting low on space on the free service (5gb) and so decided to try idrive based on this review. I was drawn to the 'sync to any folder' feature.

When I got to their site I was further impressed by the 10gb free account. Excellent. BUT: The sync to any folder is not really correct. In it's native form works like drop box and most other services, creating a sync folder. In order to use any other folder you use their "out of the box" sync feature. So I ran that. The problem is that it only syncs to the cloud. I cannot, therefore, link in three or four computers and ensure that they are all automatically synced. That is what I need, so I am back to Wuala.

Seriously, if you are needing any form of online backup or sync, please to try Wuala. I would also love to see it reviewed here.

Thanks for the comment. I'll add Wuala to the list. I drive has two different product. One is Idrive with 5 GB of storage. Idrivesync has 10 GB of storage. You can encrypt your data with Idrive and a user supplied password. This secures you files so they can only be decrypted with your password. Idrivesync does not have this option.

A while back I tried Spider Oak and decided it wasn't for me. But I have just tried it again, and I am impressed. It is very intuitive to use, and it allows sync within your existing folder structure. The 2gb free account is a bit restrictive but a quick search soon provided a discount coupan giving a freee upgrade to 5 gb. That will do nicely.

A rsvised decision. I have changed my mind about Spider Oak and have closed my account. I do a bit of offline web creation, using php and mysql. I fould that Spider Oak didn't like to sync some of the php and mysql files. Another problem I hahd was understanding exactly what it was doing. According to the online versions of my files they appeared to be split, with some held in my PC folder, some in my laptop folder. In actual fact they are all in both on my two computers.

So, out with Spider and back in with Wuala! It is faultless, intuitive and accurate. And with voucher codes I am now on 10 gb free space.

Thanks for the comment. I am going to add Wuala to my list to test and review. I read their security section and Wuala does have pre-upload encryption. Since you use Wuala, you can write a review and it will get posted to this section. Just email it to me. kyengineer Section Editor
davcock, Thanks for the comment.

SKYDRIVE is worst site by far. check the Fine Print my friends. Microsoft sifts through your files and even minor semblances of affection have been getting people banned from their Microsoft accounts. That means nothing explicit, also will ban you if you store any illegally attained downloads. so be warned..

just to let you know that Sugarsync doesn't have free storage anymore so its shouldn't be in this category.

The link to their free service is accessed from the section at the bottom of their home page. MC - Site Manager.
