What is Rsync?

Rsync is a command-line tool for fast file transfer and synchronization. It minimizes transfer size by sending only changed data.

• Delta-transfer algorithm, so only changed data transfers.
• Secure transfer over SSH.
• Ideal for backups, large file collections, and incremental sync.
• Faster than traditional FTP or WebDAV for many backup workflows.

Important Notes

• Rsync runs in rsync-only mode with no SSH shell access.
• Direct SSH commands are not supported.
• Remote paths must start with /.
• Folders are created automatically.
• Resume upload is supported with --partial.
• Designed for large file transfers and multi-GB files.
• Recommended up to 50,000 files per run.
• Recommended up to 10 concurrent sessions.

Performance Tips

• The -z compression option is not supported in this environment. Use standard rsync flags for best performance.
• Use --stats or --progress to monitor transfer performance.
• Use --partial to resume interrupted uploads.
• Rsync automatically transfers only changed data using delta transfer.
• For large uploads, split files into smaller batches for better performance.
