Plesk migration on a Windows server can be a complex process, and issues with rsync can arise due to various reasons. Here are some potential solutions to address the failure to copy files via rsync:
1. Check rsync version: Ensure you’re using the latest version of rsync compatible with your Plesk version.
2. Verify file permissions: Confirm that the source and destination directories have the correct permissions and ownership.
3. Check firewall settings: Ensure that the firewall settings on both the source and destination servers allow rsync traffic (typically TCP port 22).
4. Increase rsync timeout: Try increasing the rsync timeout value to accommodate larger files or slower network connections.
5. Exclude large files: If issues persist, try excluding large files (>1GB) and migrate them separately using a tool like Robocopy.
6. Check disk space: Ensure sufficient disk space on the destination server to accommodate the migrated data.
7. Plesk migration tool: Consider using the Plesk Migration Manager, which can simplify the migration process and handle rsync issues.
8. Manual migration: As a last resort, perform a manual migration by copying files using Robocopy or a similar tool, then updating database entries and configuring settings manually.
Remember to consult Plesk documentation and seek support from Plesk or a qualified system administrator if issues persist.
