With Super Flexible File Synchronizer (Linux), you can back up your data and synchronize 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.
Block-level copying is supported in several ways. The new Synthetic Backup mode backs up each day's changes and keeps a complete version history on the backup storage while using a minimum of storage space.
