Alternatives to GoodSync
Cross-platform file backup and two-way sync software with real-time and scheduled jobs
GoodSync ranks #1 of 11 in File sync, with an Alt Score of 93. It is proprietary, freemium from €29.95/yr and available on Windows, macOS, Linux, iOS and Android. 12 of 12 checklist rows are verified against a public source.
GoodSync is proprietary file synchronization and backup software from Siber Systems for Windows, Mac, Linux, iOS and Android. It supports real-time bidirectional sync, block-level delta transfer, versioning, and connects to local drives, NAS, FTP/SFTP, WebDAV and major cloud storage providers. It also now absorbs Allway Sync, whose vendor is migrating users to GoodSync.
GoodSync is aimed at individuals and IT teams who need to back up or synchronize files across desktops, laptops, servers, NAS devices, mobile phones, and cloud storage accounts, ranging from single-user personal backup to multi-server business deployments.
The software provides configurable one-way or two-way sync/backup jobs with real-time, scheduled, or unattended automation; block-level (delta) transfer; automated conflict resolution; version history; AES-256 client-side encryption; and connectivity to local drives, network shares, FTP/SFTP/WebDAV, GoodSync's own GSTP protocol, and major cloud providers (Google Drive, OneDrive, Dropbox, Amazon S3, Backblaze B2, Azure, and others).
Users define Jobs pairing a source and destination folder, with include/exclude filters to select specific subfolders; jobs run as a background service comparing file trees and copying only changed data blocks. Direct device-to-device transfer is handled through GoodSync Connect (GSTP protocol), which can route through GoodSync's Mediator/Forwarder service or connect directly to a self-run GSTP server when addressed directly.
