Technology is growing too fast , new technologies are invented and old are improved.If your are using old computers and your are running out of space , or if you cannot carry your usb or portable harddisk every where you can store your documents online.
Yes online or remote back up is the right solution for you.Online backup is a method of offsite data storage in which files, folders, or the entire contents of a hard drive are regularly backed up on a remote server or computer with a network connection.
There are many websites which offer online backup but following sites are the one which offer large online backup and are free.
1.Windows live Skydrive Space offered=25GB , only microsoft office files can be uploaded.
2.Dropbox Space offered=2GB for free users
3.A Drive Space offered=50GB for free users
7.Google docs Space offered=1GB
The most prominent online backup service providers stake their reputations on keeping your data safe and secure during both file transfer and the online data storage facilities. Before the files even leave your computer, they are secured using at least 128-bit SSL encryption technology. That is one of the same security measures that banks use while you are performing transactions.
But anything can happen because big networks like facebook are unreliable.Best choice should be Windows live skydrive but it only supports Microsoft office files.
