SyncBack

SyncBack is a backup and file synchronization software that allows backing up and synchronizing files to the same or different drives, to different media (CD, DVD, Flash, zip), or to a remote server. There are three versions of SyncBack available: SyncBack Freeware, SyncBackSE (shareware) or SyncBackPro (shareware). SyncBack Freeware is free for home and business use. SyncBackSE and SyncBackPro include a number of extra features, e.g. SFTP, backup to CD/DVD, 256-bit AES encryption, backup to email servers, scripting, etc. The software also offers a "verify" command which allows MD5 hash comparisons between files to ensure accurate data copying.
