How to Use Rsync to Copy Files Over SSH

Use Rsync to Copy Files

Introduction

Rsync, sometimes known as Remote Sync, is a free command-line utility that allows you to transfer files and directories to both local and remote locations. Rsync is used for mirroring, backups, and data migration to other servers.

This program is quick and efficient, replicating only the changes from the source and allowing for customization.

Set up an SSH connection with the destination server.

Rsync over SSH can use a standard login with a password or a Private key for SSH authentication

In this example, I’m going to copy a file from Server A (192.168.182.130) located in /root/file-to-send.zip to Server B (192.168.182.131) and save it to /root/new-file.zip.

Step 1 : Connect to server A and locate the file.

$ ssh [email protected]_ip
$ ls
Output:
[email protected]:~# ssh [email protected]
[email protected]'s password:
[email protected]:~# ls
file-to-send.zip

Step 2 : Use rsync to transfer the file.

$ rsync -avz /root/file-to-send.zip [email protected]_ip:/root/new-file.zip
Output:
[email protected]:~# rsync -avz /root/file-to-send.zip [email protected]:/root/new-file.zip
sending incremental file list
file-to-send.zip
sent 10,600 bytes received 35 bytes 21,270.00 bytes/sec
total size is 131,604 speedup is 12.37

When you transfer large files, it’s more user-friendly to have a progress bar with --progress.

Our command will become :

$ rsync -avz /root/file-to-send.zip [email protected]_ip:/root/new-file.zip --progress 
Output:
[email protected]:~# rsync -avz /root/file-to-send.zip [email protected]:/root/new-file.zip --progress
sending incremental file list
file-to-send.zip
131,604 100% 94.26MB/s 0:00:00 (xfr#1, to-chk=0/1)
sent 10,600 bytes received 35 bytes 7,090.00 bytes/sec
total size is 131,604 speedup is 12.37

-v, –verbose:This option is used if the user wishes to know what the computer is doing while running the command.

-a, –archive:This option can be used to archive files when synchronization is taking place.

-z, –compress:This option can be used to compress the file being transferred to reduce data usage during synchronization.

Step 3 : Checking the transfer of file.

Finally, do not forget to verify that you have received the file on server B.

$ ssh [email protected]_ip
$ ls
Output :
[email protected]:~# ssh [email protected]
[email protected]:~# ls
new-file.zip snap
