SyncBackFree is a free file backup & synchronization program that can be used with hard drives, rewritable CD’s & DVD’s (formatted with UDF), removable media (e.g. Compact Flash), FTP servers, ZIP archives, and network shares. It’s easy to use, but includes many options for the power user.
For more powerful features, e.g. cloud, more FTP features, SFTP, FTPS, better compression and encryption, scripting, and more, take a look at SyncBackPro.
