To do so, you can use the -p flag in the command line. Plus, Linux Rsync to remote server utility enables you to use these two features simultaneously. You can also know the current file transfer progress through the –progress option. For instance, using the –partial option enables you to continue the previous partial transfer in case of issues like Rsync interruption. Rsync to remote server over SSH has other options that can be pretty helpful. READ How to Change the SSH Port in Linux | A Quick Step-by-Step Guide to Your SSH Port rsync -av -e ssh 1998 sourceDir/ the above command, we assume we want to use 1998 as our SSH port rather than 22. Look at the following command to understand how it works. If you want the SSH connection to be accepted over a port other than the default (port 22), you need to mention the port number after -e ssh. Note that -e ssh option demands Rsync connection to be over SSH protocol. This command includes other options you should be familiar with, like -a (archive) and -v (verbose). Please pay attention to the following command to understand how it works: rsync -av -e ssh /sourceDir/ the above command will help you sync sourceDir and destinationDir. Making incremental backups is one of Rsync over SSH use cases. How to Create Backups Using Rsync over SSH? In the following section, we will discuss how to use this tool’s capability to make backups via key-based authentication. You now need to start and then enable Rsync to begin using it via the following commands: sudo systemctl start rsync sudo systemctl enable rsync Step 4: Verifying Rsync InstallationĮnter the following command to ensure whether you have installed Rsync correctly and to check which version you are using on your Linux system: rsync -version Note: apt is a helpful package installation tool used in Debian-based distributions. If you are using other Linux distributions, like Fedora, CentOS, AlmaLinux, and Red Hat, type the following command to install Rsync to remote server service on your system: sudo dnf install rsync The following command will enable you to install Rsync on Ubuntu, Linux Mint, and Debian: sudo apt install rsync -y You should also ensure that the local server has administrative privileges (sudo). To Rsync to a remote server, you will need to have a local server, aka the source, and the remote server. You can check the version of SSH using the following command: ssh -V Before doing so, Please pay attention that SSH must already be installed in both source and destination systems as we want to use Rsync over SSH. You probably already have Rsync installed on your system nonetheless, let’s get into detail. You should also note that Rsync employs compression and decompression for receiving and sending data, leading to less bandwidth usage. Therefore, as an alternative solution to these issues, we can use Rsync to remote server with key based encryption(simply called Rsync SSH or Rsync over SSH) which prevents sending duplicated data and utilizes an SSH key. FTP does not include data encryption which is not what we hope for, and even though SCP doesn’t have an unencrypted transfer problem like FTP, it still takes more time for transferring as it makes a tunnel to do so. However, these two both come with drawbacks. The question is, what makes Rsync tool unique when compared to other utilities or commands?įor instance, you can use File Transfer Protocol (FTP) to have a local copy of your website or SCP (Secure Copy Protocol) for this task. Why Use Rsync?Īs you may already know, various backup tools are available to employ. In other words, using the Rsync command will help you avoid losing time for blind data transfer as it just considers the differences between the two Linux systems. The main idea behind using Rsync to remote server is to take advantage of its fast file transfer to transform data between two sources, it only considers the differences between them. Additionally, you can mirror your Linux system to another one. Using Rsync command lets you perform various data-related tasks, such as synchronization, copying, and getting backups. Remote Sync (Rsync) is a well-known Linux/Unix command that you can use for copying and synchronizing files and directories through remote access or locally. 8.2 What is Rsync? What Is Rsync Utility?
