10 Practical Examples of Rsync Command in Linux

 https://www.tecmint.com/rsync-local-remote-file-synchronization-commands/

 

1. Copy/Sync Files and Directory Locally

 

2. Copy/Sync a Directory on Local Computer

3. Copy/Sync Files and Directory to or From a Server

 

4. Rsync Over SSH

 

5. Show Progress While Transferring Data with rsync

 

6. Use of –include and –exclude Options

 

7. Use of –delete Option

If a file or directory does not exist at the source, but already exists at the destination, you might want to delete that existing file/directory at the target while syncing.

 

8. Set the Max Size of Files to be Transferred

this command will transfer only those files which are equal to or smaller than 200k.

 

9. Automatically Delete source Files After Successful Transfer
