Advanced Integration Scenarios

Bidirectional Sync

If you need files to sync in both directions, you can set up two separate sync operations:

rclone sync my-sftp:/path sftp-to-drive:/path

rclone sync my-gdrive:/path drive-to-sftp:/path

Be careful with bidirectional sync to avoid conflicts or unintended file deletions.

Selective File Sync

To sync only specific file types:

rclone sync my-sftp:/path my-gdrive:/path --include "*.pdf" --include "*.docx"

Real-time Sync

For near real-time syncing, you can:

• Use Rclone's --monitor flag to watch for changes
• Set up a frequent cron job (e.g., every 5 minutes)
• Use filesystem events to trigger sync operations

Case Studies: Real-world Applications
