You’ll be prompted for the SSH password after entering the command. Specify the remote SSH user and destination directory in the command as well. To run rsync through SSH, we can add the -e ssh option in our command. One of rsync’s most powerful features is that it can also be used with remote systems.

It’s the one you should try hardest to remember, as you’re likely to resort to it often. The syntax below is probably the most common form of rsync that you will see. To get more information about the current transfer, you can add the -v (verbose) option to the command. The previous command won’t produce much output, unless an error occurs.Notice also the trailing slash on our directories, which will avoid creating an additional directory level at the destination. However, rsync has combined all these options into the single -a (archive) switch, so we can use all the most common options with just one flag. All these options combined ends up being -rlptgoD. This includes recursive transfer, the transfer of file modification times, file permissions, symbolic links, etc. There are a bunch of options that are really common to use with rsync.To get started, use some of the following commands on your own system, and you’ll quickly have it mastered. It’s easiest to learn about rsync through examples. $ – requires given linux commands to be executed as a regular non-privileged user # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command

In this guide, we’ll learn how to use the rsync command through examples. If you learn about rsync from the basics, it’s easy to wrap your head around. In reality, it can be very complex, but rsync only gets complicated when you need to do specific things. Many backup utilities use rsync in some form or another, because some users don’t bother to learn how to use the rsync command. This makes rsync work very well as a backup tool, on top of file copying. It’s also a very secure utility, utilizing SSH for remote file transfers. And when a file changes in the source directory, rsync can efficiently synchronize the contents to the destination directory, only transferring the bits that have changed. In other words, it can take a source directory and make an identical destination directory. Some users mistakenly think of rsync as a file copying tool, like cp or scp.While there’s some overlap, rsync excels in synchronization, specifically. It’s built into nearly every Linux system by default and this tutorial will help you to understand rsync better by providing you most common rsync examples administrators use to keep the data synchronised across multiple server/hosts. Rsync stands for “remote sync” and is a powerful command line utility for synchronizing directories either on a local system or with remote machines.
