1. Overview GoodSync Pro is a cross-platform file synchronization and backup software developed by Siber Systems. Unlike simple cloud storage clients (e.g., Google Drive or Dropbox) that operate within a single ecosystem, GoodSync Pro acts as a universal bridge, enabling bi-directional and one-way synchronization between a wide range of storage types. These include local folders, external drives, network attached storage (NAS), SFTP/FTPS servers, WebDAV, and major cloud providers (Google Drive, OneDrive, Amazon S3, Dropbox, Box, etc.).
Its primary weakness – complexity – is also its strength: no other commercial tool offers the same combination of protocol support, efficiency, and granular control. If you regularly manage sync between local drives, NAS, SFTP, and multiple clouds without wanting to write custom scripts, GoodSync Pro is well worth the license fee. For simple folder mirroring on a single PC, a free tool like FreeFileSync or a cloud client may suffice. goodsync pro
