I have discussed this application in recent post and still think that Dropbox is the best free service that I have found, so I will not go into details here. The great thing is that you get 2 GB FREE Space for just signing up and you can actually get up to 8 GB of FREE space for just referring friends. The one thing that I have found out is that the person that you have invited must install Dropbox on their computer or else you will not get your extra space.
IDrive has a basic account, similar to other on-line storage applications, where you can get 5 GB of FREE initial online backup space and an additional 15 GB of space just for inviting others.
IDrive has a great feature if you use WordPress. There is a WordPress plugin available that makes it easy to automatically backup your WordPress data which includes your files and the MySQL database, based on your configuration. I use this to backup all of my websites and it works in the background. The nice thing about this is that when your files are backed up you get an email notification.

You can install ZumoDrive on as many computers as you like so that you have the capabilities to access to saved documents, no matter which computer was used to save the files.
According to the website, you can use more than one email address and link multiple email addresses to a single ZumoDrive account. This is a nice feature if you do a lot of texting of files from your hand-held device.
You can get 2 GB just for signing up and a maximum of 5 GB extra free space just for inviting others to download and install the application.

I just came across this application the other day and thought that I would try it out. You will get an initial 2 GB FREE of space just for signing up and no more space unless you pay for the service.
According to Wuala, it will store and back up your files online and allow you access your files from anywhere.
You can also sync your files online and across multiple computers that you have.
You can share your files with selected friends and co-workers and decide who has access to which folder in your system.
Summary
I have only provided a brief summary of the FREE use of each of these applications. You will need to visit each website to determine what application works for you. The bottom line is for me: Dropbox is my favorite. Any my second favorite is IDrive as I use this service only for my wordpress backups. The other two mentioned here are do have some good things about them, as the amount of FREE space that you do get. I typically only use the FREE space. The problem is that if you have too many of these cloud applications; you will forget which system has which files stored.
The last thing that I would say before closing is that all of these services provide some level of security of your files, as all services state that there is some level of encryption. But, in my opinion, the best common sense rule that I can provide you is to only store files and folders remotely that are not senstive in nature. For example, I would not store any files such as bank records, social security numbers, tax records, etc, as these to me are very sensitive and should be stored in a safe place.
I appreciate your support and look for your feedback.
