I just needed an online backup option, so first i thought of windows live drive, with an application will will make it a drive. But Norton blocked that installation :).
So i just have search and find 3 online backup services, all 3 are good. All three have Client software's which will help you to automate the backup processes.
It is recommended that you keep your backup in a different place. Am backing up my data on an external hard disc that will be used when some hard disc issues happens. Online backup is to use if some disaster occurs and if i lost both my hard disc data (External and Internal). So it will be better if you can select an online backup, and backup your data.
Mozy will give you 2GB of free space. And you can install an application which will take care of the scheduled backup. So it is a kind of set up and forget type of backup.
The Client will support OS X and Windows.
Open/locked file support: Mozy will back up your documents whether they're open or closed.
128-bit SSL encryption: The same technology used by banks secures your data during the backup process.
448-bit Blowfish encryption: Secures your files while in storage, providing peace of mind that your private data is safe from hackers.
Automatic: Schedule the times to back up and MozyHome does the rest.
New and changed file detection: MozyHome finds and saves the smallest changes.
Backs up Outlook files: Disaster-proof email protection.
Block-level incremental backup: After the initial backup, MozyHome only backs up files that have been added or changed, making subsequent backups lightning fast.
If you are referring a friend to Mozy both of you will get 256MB of additional storage. So here is my referral link to Mozy, if you are using this we both will get 256MB additional space (As of now you can get unlimited storage by referring friends).
