FreeFileSync

FreeFileSync is a free backup software that helps you to compare and synchronize files and folders on Windows, Linux and Mac OS X. It is designed to save your time setting up and running backup jobs while having nice visual feedback along the way.

Features: Detect moved and renamed files and folders. Copy locked files (Volume Shadow Copy Service). Detect conflicts and propagate deletions. Binary file comparison. Configure handling of Symbolic Links. Automate sync as a batch job. Process multiple folder pairs. Comprehensive and detailed error reporting. Copy NTFS extended attributes (compressed, encrypted, sparse). Copy NTFS security permissions. Support long file paths with more than 260 characters. Fail-safe file copy. Cross-platform: Windows, Linux, Mac OS X. Expand environment variables like %USERPROFILE%. Access variable drive letters by volume name (USB sticks). Native 64-bit support. Keep versions of deleted/updated files. Prevent disc space bottlenecks via optimal sync sequence. Full Unicode support. Highly optimized runtime performance. Include/exclude files via filter. FreeFileSync portable and local installation available. Handle daylight saving time changes on FAT/FAT32. Use macros %time%, %date%, et al. for recurring backups. Case-sensitive synchronization. Built-in locking: serialize multiple jobs running against the same network share.
