✅ Step-by-Step Guide:
1. Basic Local File Copy:
rsync -av /source/directory/ /destination/directory/
-a : Preserves file attributes (permissions, timestamps).
-v : Enables verbose output.
Trailing slashes (/) ensure directory contents are copied.
2. Sync with Deletion:
rsync -av --delete /source/directory/ /destination/directory/
Ensures destination matches source exactly (removes extra files).
3. Remote File Transfer:
rsync -avz /local/directory/ user@remote:/remote/directory/
-z : Compresses data during transfer for better performance.
4. Dry Run:
rsync -av --dry-run /source/directory/ /destination/directory/
Simulates the operation without making changes.
5. Exclude Files:
rsync -av --exclude='*.tmp' /source/directory/ /destination/directory/
Excludes temporary files from the transfer.
6. Show Progress:
rsync -av --progress /source/directory/ /destination/directory/
Shows real-time transfer statistics for each file.
✅ Why Use rsync?
⚡ Delta Transfer: Only sends changed parts of files.
🔒 Preserves Attributes: Maintains permissions, timestamps, etc.
🌐 Remote Capabilities: Works seamlessly with SSH.
🛠️ Flexible Options: Exclude, resume, compress, and more.
✅ Pro Tips:
Use -P (same as --partial --progress ) for large file transfers.
Always test with --dry-run before executing destructive syncs.
Combine with cron for automated backup schedules.
