Syncovery

Syncovery is back up your data and synchronizes PCs, Macs, servers, notebooks, and online storage space. You can set up as many different jobs as you need and run them manually or using the scheduler. The software comes with support for FTP, SSH, HTTP, WebDAV, Amazon S3, Google Docs, and Microsoft Azure Storage. You can use ZIP compression and data encryption. The scheduler can run as a service - without users having to log on. There are powerful synchronization modes, including Standard Copying, Exact Mirror, and SmartTracking.
