AASync

From RBrowser:

AASync is a Secure File Backup, Folder Sync utility for Mac and Windows. It is simple to use, and it allows local as well as remote backups over an FTP or SFTP connection. Makes it very easy to back up your files to a remote server or another local disk or maintain your website! The sync engine will detect the changes, and copy only the changed files for efficiency. Here are the main features: Folder Synchronization: Local-to-Local,Local-to-Remote and Remote-to-Local. Run as many syncs simultaneously as you want. Schedule your sync ops. Encrypt your data if you want security, there are plenty of options. Ability to ignore certain files or file types. Proxy/Firewall support (SOCKS, Firewall toolkit). Secure file transfers using ssh encryption. Very simple to use, but feature rich. Fast backups due to the two-phase sync engine that in most cases does not need to browse the remote host to detect changes. Different sync modes let you control how the sync is run. Copies open files using the Shadow Copy Service (VSS). Sync logs can be mailed to the admin automatically.
