IDrive
Get 5 GB of full featured Online Backup for free. Features include Automatic Backup, True Archiving, Versioning, Continuous Backup, Mapped Drive Backup and Web-based Backup Management. IDriveSync syncs files online across multiple PCs and Macs. On installing and logging into the application, it opens up a 'Sync' area where you can add the files you wish to sync. With iDrive Sync you can Sync up to 5 computers: Once you have new data into your Sync area, your Sync data starts getting transferred online, or 'Syncs-Up'. This essentially serves as an online backup of your data. Now, if you simply install and login on multiple PCs / Macs using same authentication, the synced data is 'Synced-Down' onto those multiple computers. Anytime you make a change to synced data anywhere on those multiple computers, all the computers will shortly reflect the modified data.
