The archive mode behaves like the recursive mode but keeps all file permissions, symbolic links, file ownership, etc. We will list some of the most common rsync options.Īllows to sync data recursively but does not keep ownership for users and groups, permissions, timestamps, or symbolic links. You can enter rsyncin your terminal and get all the details. Remote data transfers require you to specify a host’s address, but more on that later.

Rsync syntax in its most basic form looks like this: rsync options SOURCE DESTINATION We will cover all the scenarios in the following examples. The syntax for the rsync command changes depending on the usage of the tool. Show the Difference Between the Source and Destination Files Do Not Copy Source File if the Same Destination File is Modified Delete a Nonexistent Source File or Directory from Destination Copy Multiple Files or Directories from Local to Remote Machine Copy a File or Directory from a Remote to a Local Machine Specify rsync Protocol for Remote Transfers Copy a File or Directory from Local to Remote Machine Copy a Directory and All Subdirectories Locally (Copy Files and Directories Recursively) There will probably come a time when you need to do this in the future. If you don't, keep reading but take a mental note. doesn't that sound like dropbox? Yup! There are tons of other features that Dropbox has that rsync doesn't, but at the gist of it, dropbox is a fancy and glorified rsync with durability added.įor this section, if you're coding along, I am assuming that you have access to a remote server. If you have access to a remote server, you can quickly sync your directory locally with a remote server, vice versa. You can use rsync over a network connection. It is safe to say you will want to run rsync -a 90% of the time. The big picture is, running rsync -a preserves all the important metadata when transferring files. -o preserves owner (only for super-user).-p preserves file permissions / privileges.-l copies symlinks and keep them as symlinks.Whoa, that's a lot of options! Don't worry, let's break it down: This is analogous to running rsync -rlptgoD. If you read online articles about rsync, you will notice that many developers use the -a command ( -archive). Break things! Just make sure you make a backup first (see what I did there? :D) Only by doing these you'll get the most out of this article.Īt its core, the rsync command looks like this:Įnter fullscreen mode Exit fullscreen mode Moreover, don't just type everything you see in this article and stop there. I find it more useful when learning a new thing if I actually type the commands.

I would strongly encourage you to code along. Why copy mostly the same data if you can just copy only the differences? This lets you minimize the network usage, which can be useful if you have a small bandwidth. You will only have to transfer 0.1GB of data. With rsync, you won't have to copy the whole 1.1GB of data from A to B. Then you add small changes of about 0.1GB. Assume that you also have directory B with the same 1GB of files. Suppose that your source directory A contains files totaling 1GB in size. cp copies everything from one location to another, while rsync copies the deltas (the differences) from one location to another. Some of you may wonder, 'Well, why can't I just use the copy command cp, that way I don't have to learn a new command?' These two are two different programs. These directories can be inside the same machine or between two connected machines.

It is a tool to transfer and synchronize files in different directories. If you've been programming for a while, you may have heard of rsync.
