How to Use Rsync Command in Linux: 16 Practical Examples

Rsync (Remote Sync) is the most commonly used command for copying and synchronizing files and directories remotely as well as locally in Linux/Unix systems.

With the help of the rsync command, you can copy and synchronize your data remotely and locally across directories, disks, and networks, perform data backups, and mirror between two Linux machines.

This article explains 16 basic and advanced uses of the rsync command to transfer your files remotely and locally in Linux-based machines. You don’t need to be a root user to run the rsync command.

Advantages of Rsync Command

It offers several advantages, including:

  • Efficient File Transfer – rsync uses a delta transfer algorithm, which means it only transfers the differences between source and destination files, which significantly reduces the amount of data transferred, making it efficient for syncing large files or directories.
  • Remote File Synchronization – rsync supports both local and remote file transfers over SSH, which allows synchronization between local and remote systems or mirroring directories across multiple machines.
  • Incremental Backups – rsync is well-suited for incremental backups, as it create and update backups efficiently by transferring only new or modified files.
  • Preserves File Permissions – rsync can preserve various file attributes, such as permissions, ownership, timestamps, and symbolic links, which ensures that the copied files retain their original characteristics on the destination.
  • Bandwidth Control – rsync allows you to limit the bandwidth usage during file transfers, as it uses compression and decompression method while sending and receiving data on both ends.
  • Faster – rsync can be faster than scp (Secure Copy) for transferring files, especially when syncing large directories or when dealing with files that have already been partially transferred or exist on the destination.

Rsync Command Syntax

The rsync command follows the following syntax:

# rsync [OPTIONS] SOURCE DESTINATION

Here’s an explanation of the different components and options used with rsync commands:

  • -v – Verbose output, displaying detailed information about the transfer.
  • -r – copies data recursively (but doesn’t preserve timestamps and permission while transferring data.
  • -a – archive mode, which allows copying files recursively and it also preserves symbolic links, file permissions, user & group ownerships, and timestamps.
  • -z – Compress files during transfer to reduce network usage.
  • -h – human-readable, output numbers in a human-readable format.
  • -P – Show progress during the transfer.
  • SOURCE – Specifies the source file(s) or directory to be transferred, which can be a local or a remote location.
  • DESTINATION – Specifies the destination path where the files or directories will be copied. Similar to the source, it can be a local path or a remote location.

Install Rsync in Linux System

We can install the rsync package with the help of the following package manager as per your Linux distribution.

$ sudo apt install rsync         [On Debian, Ubuntu and Mint]
$ sudo yum install rsync         [On RHEL/CentOS/Fedora and Rocky/AlmaLinux]
$ sudo emerge -a sys-apps/rsync  [On Gentoo Linux]
$ sudo apk add rsync            [On Alpine Linux]
$ sudo pacman -S rsync           [On Arch Linux]
$ sudo zypper install rsync      [On OpenSUSE]    

1. Copy/Sync File Locally

To copy or sync a file locally, you can use the following command that will sync a single file on a local machine from one location to another location.

Here in this example, a file name backup.tar needs to be copied or synced to /tmp/backups/ folder.

[root@tecmint]# rsync -zvh backup.tar.gz /tmp/backups/

created directory /tmp/backups
backup.tar.gz

sent 224.54K bytes  received 70 bytes  449.21K bytes/sec
total size is 224.40K  speedup is 1.00

In the above example, you can see that if the destination is not already existed rsync will create a directory automatically for the destination.

2. Copy/Sync Directory Locally

The following command will transfer or sync all the files from one directory to a different directory in the same machine.

Here in this example, /root/rpmpkgs contains some rpm package files and you want that directory to be copied inside /tmp/backups/ folder.

[root@tecmint]# rsync -avzh /root/rpmpkgs /tmp/backups/

sending incremental file list

3. Copy a Directory from Local to Remote Server

To copy a directory from a local server to a remote server, you can use the following command, which will sync a directory from a local to a remote machine.

For example, if there is a folder in your local computer “rpmpkgs” that contains some RPM packages and if you want that local directory’s content sends to a remote server, you can use the following command.

# rsync -avzh /root/rpmpkgs [email protected]:/root/

5. Rsync Over SSH

With rsync, we can use SSH (Secure Shell) for data transfer, using SSH protocol while transferring our data you can be ensured that your data is being transferred in a secured connection with encryption so that nobody can read your data while it is being transferred over the wire on the internet.

Also when we use rsync we need to provide the user/root password to accomplish that particular task, so using the SSH option will send your logins in an encrypted manner so that your password will be safe.

To use rsync over SSH, you can use the -e option to specify the remote shell command, which is typically ssh as shown.

# rsync [OPTIONS] -e ssh /path/to/source user@remote:/path/to/destination

6. Copy a File from a Remote Server to a Local Server with SSH

To synchronize a file from a remote server to a local server, you can specify a protocol with rsync using the “-e” option with the protocol name you want to use.

Here in this example, We will be using the “ssh” with the “-e” option and perform data transfer.

# rsync -avzhe ssh [email protected]:/root/anaconda-ks.cfg /tmp

[email protected]'s password: 
receiving incremental file list

7. Copy a File from a Local Server to a Remote Server with SSH

To synchronize a file from a local server to a remote server using SSH, you can leverage the following command as shown.

# rsync -avzhe ssh backup.tar.gz [email protected]:/backups/

[email protected]'s password: 
sending incremental file list
created directory /backups
backup.tar.gz

sent 224.59K bytes  received 66 bytes  64.19K bytes/sec
total size is 224.40K  speedup is 1.00

8. Show Progress While Transferring Data with Rsync

To show the progress while transferring the data from one machine to a different machine, we can use the ‘--progress' option, which displays the files and the time remaining to complete the transfer.

# rsync -avzhe ssh --progress /root/rpmpkgs [email protected]:/root/rpmpkgs

[email protected]'s password: 
sending incremental file list
rpmpkgs/

9. Include Files with Particular Extension with Rsync

To include specific files or patterns during a rsync operation, you can use the --include option with an extension that matches all files.

# rsync -avz --include='*.txt' /path/to/source/ user@remote:/path/to/destination/

In the provided example, rsync will include only files with the .txt extension from the /path/to/source/ directory during the transfer.

10. Exclude Files with Particular Extension with Rsync

Similarly, to exclude a specific extension during a rsync operation, you can use the --exclude option with a wildcard pattern.

# rsync -avz --exclude='*.ext' /path/to/source/ user@remote:/path/to/destination/

In the provided example, rsync will exclude files with the specified extension (*.ext) during the transfer, while including all other files and directories.

11. Include and Exclude Files with Rsync

To include and exclude specific files or patterns during a rsync operation, you can use both the --include and --exclude options with appropriate wildcard patterns.

These two options allow us to include and exclude files by specifying parameters these option helps us to specify those files or directories which you want to include in your sync and exclude files and folders with which you don’t want to be transferred.

Here in this example, the rsync command will include those files and directories only which starts with ‘R’ and exclude all other files and directories.

# rsync -avze ssh --include 'R*' --exclude '*' [email protected]:/var/lib/rpm/ /root/rpm

12. Use of –delete Option with Rsync

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.

We can use the ‘--delete‘ option to delete files that are not there in the source directory.

The source and target are in sync. Now create a new file test.txt at the target.

[root@tecmint:~]# cd /root/rpm/
[root@tecmint:~/rpm]# touch test.txt
[root@tecmint:~/rpm]# rsync -avz --delete [email protected]:/var/lib/rpm/ /root/rpm/

13. Set File Transfer Limit with Rsync

You can specify the Max file size to be transferred or synced. You can do it with the “--max-size” option. Here in this example, the Max file size is 200k, so this command will transfer only those files which are equal to or smaller than 200k.

# rsync -avzhe ssh --max-size='200k' /var/lib/rpm/ [email protected]:/root/tmprpm

14. Automatically Delete Source Files After Transfer

Now, suppose you have the main web server and a data backup server, you created a daily backup and synced it with your backup server, but now you don’t want to keep that local copy of the backup in your web server.

So, will you wait for the transfer to complete and then delete that local backup file manually? Of Course NO. This automatic deletion can be done using the ‘--remove-source-files‘ option.

# rsync --remove-source-files -zvh backup.tar.gz [email protected]:/tmp/backups/

[email protected]'s password: 
backup.tar.gz

sent 795 bytes  received 2.33K bytes  894.29 bytes/sec
total size is 267.30K  speedup is 85.40

[root@tecmint:~]# ls -l backup.tar.gz

ls: cannot access 'backup.tar.gz': No such file or directory

15. Do a Dry Run with Rsync

If you are a newbie using rsync and don’t know what exactly your command going to do. Rsync could really mess up the things in your destination folder and then doing an undo can be a tedious job.

Use of this option will not make any changes to the files and shows the output of the command, if the output shows exactly the same as you want to do then you can remove the ‘--dry-run‘ option from your command and run on the terminal.

# rsync --dry-run --remove-source-files -zvh backup.tar.gz [email protected]:/tmp/backups/

[email protected]'s password: 
backup.tar.gz

sent 50 bytes  received 19 bytes  19.71 bytes/sec
total size is 267.30K  speedup is 3,873.97 (DRY RUN)
Rsync Dry Run

16. Rsync Set Bandwidth Limit and Transfer File

You can set the bandwidth limit while transferring data from one machine to another machine with the help of ‘--bwlimit‘ option. This option helps us to limit I/O bandwidth.

# rsync --bwlimit=100 -avzhe ssh  /var/lib/rpm/  [email protected]:/root/tmprpm/
[email protected]'s password:
sending incremental file list
sent 324 bytes  received 12 bytes  61.09 bytes/sec
total size is 38.08M  speedup is 113347.05

Also, by default rsync syncs changed blocks and bytes only, if you explicitly want to sync the whole file then you use the ‘-W‘ option with it.

# rsync -zvhW backup.tar /tmp/backups/backup.tar
backup.tar
sent 14.71M bytes  received 31 bytes  3.27M bytes/sec
total size is 16.18M  speedup is 1.10
Conclusion

That concludes our overview of rsync and its capabilities. For further exploration of its extensive options and functionalities, I encourage you to refer to the comprehensive manual pages (man pages) available.

  1. None of these commands will be executed as written. They are prefixed with a hash mark (#) which in Linux indicates a comment.

    Reply
    • @deagonmouth,

      In Linux, the # symbol is used to indicate that the command is being run by the root user, which is a superuser, and has full administrative privileges on the system.

      When you are logged in as the root user, your prompt will be prefixed with a # symbol, which is used to indicate that you are running commands with root privileges.

      I hope this helps!

    Now in my local machine i.e. laptop (Windows10), the ‘rsync’ is not installed. So, when i typed the command “rsync -avzh [space]e:” it says ‘rsync’ not recognised.

    so. my question is

    rsync error: syntax or usage error (code 1) at main.c(1285) [Receiver=3.1.3]

    the error meaning is straight forward but, I am giving this command where I access Linux through ‘ssh’ and gave this command. Does this make difference?

  13. Hello friends,

    Can any one tell me how to keep update my backup machine.

    The problem is here.

    Source to destination synchronization need to be 100% accurate. Actually I have 2 servers that I need to be sync (100% copy of each other). I have tested it in the following way.

    rsyncdemo dir on both servers that I need to synchronize that contains further sub folders and files.
    Test 1:

    # rsync -uvr -e ssh  /rsyncdemo [email protected]:/rsyncdemo 
    

    It copies all data successfully no issues. but problem is that if I delete a file or folder on the source machine it do not delete it from the destination.

    Test2:

    # rsync -uvr --delete -e ssh  /rsyncdemo [email protected]:/rsyncdemo 
    
    It checks on both servers if I deliberately delete a file from the source. The rsync command check it on destination and copy it back to source machine.
    I want to keep the destination machine up to date according to the source machine. 
    
    How to block/restrict the rsync no to copy any file or folder from the destination to source.
    
    Thanks in Advance

  14. I’m using rsync, talking to a rsyncd, to avoid encryption through ssh, as the rsyncing machines are low powered embedded boards. Consequently, the rsyncd provides modules to address the server directories, say, a module “backup”.

    A client machine now attempts to sync some local directories to a corresponding path under the directory, specified by module on rsyncd machine, like:

    # rsync $options $path/$dir server::backup/$path
    

    But as long as $path doesn’t exist on the server, rsyncing $dir fails. I’m looking for a way to create $path on the server automatically when written to, akin to what mkdir -p does. Given that the canonical path on server is hidden behind the module name, letting client ssh to a server in order to create the directory prior to rsync is something I want to avoid.

    I haven’t found an rsync option allowing the creation of destination directories on a needs base. Do you have any suggestion how to solve this case, short of manually creating destination directories prior to first use?

    I was thinking of some intricate scheme of iterating through parent directories, rsyncing each level of parent directories while excluding all siblings until decided to the source directory. While this could possibly work (untested), I doubt that this effort is actually meant to be necessary for this presumably rather common use case.

    Thank you for any suggestion.

    Reply
    • I’m now considering a refinement to the thought of method above: Rather than iterating through directories, rsyncing each level separately for the creation of a single directory level, I’m now considering to try creating the whole path in a temporary directory, rsyncing all of those in one go, then removing the temporary directories again.

      In consequence, the whole path has been created on the server, ready to commence the actual data transfer to its deepest level directory. Less effort already, but still rather Rube Goldbergish – more ideas still welcome.

      Reply
      • I’ve now, at least for the time being, settled for the described approach:

        * creation of temporary directory (mktemp -d)
        * creation of wanted path in temp directory (mkdir -p)
        * rsync top level directory of wanted path from temporary directory (rsync – this creates wanted the directory hierarchy on server)
        * removal of temporary directory (rm -r)
        * rsync $path dest::module/$path # as destination directory already exists, rsync proceeds without failure.

        while probably not the most elegant method, the additional complexity is manageable: no iterating through path components, or other path decomposition. just plain use of path components already existing for scripting purposes. So unless a better (working) idea pops up, I’m happy for now. Thank you all for bearing with me.

        Reply
    • The trick is to put trailing slashes on the paths:

      # rsync $options /my/files/source/ server::backup/files/target/
      

      Directory “source” will be named “target” at the receiving system. Provide the exact name you want.

      • Actually, there is a trailing slash in the source path, which got hidden behind using the variable $dir. A copy and paste of an actual and complete call are here (well, not quite actual, I simplified options a bit, but the result is the same):

        # rsync -av /home/l/read/tips/ buffalo::backup/vpn/home/l/read/
        sending incremental file list
        rsync: mkdir "vpn/home/l/read" (in backup) failed: No such file or directory (2)
        rsync error: error in file IO (code 11) at main.c(656) [Receiver=3.1.1]
        (11:46:52) root@vpn ~ # 
        

        Using or not using a trailing slash makes no difference here. rsync succeeds as soon the directory vpn/home/l/read is manually created under the directory representing module backup. This is the case regardless whether the destination is specified by module name or by canonical name over ssh.

        Another thought came up which I may have to try out: Exclude everything by option, then include the topmost directory of the wanted path. Current “solution” is still to create destination directories manually when necessary.

        Reply
        • Regarding about my previous comment: “then include the topmost directory” won’t do, as this transfers the unwanted siblings too. The whole path, down to deepest source directory, should be needed.

          Reply
          • I don’t know why it differs for you. I have no trouble with this and I do it all the time (Linux). Here’s one I just used last weekend, worked like a charm.

  15. Hi,

    If I set rsync the folder of the files will get automatically change or need to set some cron for that? Please help me out.

    Reply
    • You could have a look at lsyncd, which watches for modification on files through inotify, then transfers the modified files using rsync upon modification.

      An alternative could be incrontab to do essentially the same. Latter is a more general approach, as incrontab can be used for other actions than rsync. Both methods will allow you to monitor changes and rsync those automatically shortly after they took place.

      Reply
      • It seems comments get edited prior to being published. I noticed earlier that words were edited, unfortunately introducing errors that way. Same here: I originally wrote “incrontab“, not “in crontab”. While cron merely executes by time specification, incrontab allows inotify event specification, which is what I was actually referring to: https://linux.die.net/man/1/incrontab

  16. Hello, is there any way to produce an exit code if it sees that source and destination are not the same while using the option –dry-run? Thanks

    Reply
  17. When rsyncing from local to local, compressing only slows it down. Skip the -z option if you’re backing a local disk up to a local disk, because it’s just reading the whole file, compressing it, decompressing it, and writing the whole file. No need for the compression middleman if the sync isn’t over a network.

  20. Hi,

    With Rsync command I want only copy/sync changed files/folder to the destination folder. I had some issue with Rsync-like whenever am executing the Rsync command am copied along with the time stamp as well.

    For example, my destination folder ‘Linux’ had updated on 30th June and in my source folder there is no update info for the Linux folder, but when am performing the Rsync command my destination Linux folder time stamp has been updated with source folder time stamp. I don’t want to copy the timestamp as well. please suggest me on this and please glance on below command which I have used.

    rsync -avh /source/Linux/ /destination/Linux/

      You can use following command to only sync new or changed files over rsync to destination folder:

        • @Raja,

          Yes, the -n option is used to check the files, and once you confirm that the files are listed correctly on the dry-run, remove the -n option and run:

          # rsync -ua /source/Linux/ /destination/Linux/

    You mentioned in one of your examples that you could transfer the contents from source to destination securely over ssh when you use the “-e” option and specify ssh. May i know that over what protocols is the transfer done when not using ssh option?

    Reply
    • @Gaurav,

      Yes, I do mentioned that you can transfer files from source to another securely using SSH, but still it all depends on which protocol you configured under sshd_config file, I suggest to use Protocol 2 for more better security in SSH configuration file..

  22. rsync works great but how do I get it to keep using the entire network bandwidth for really large files, 1tb+? I’m hitting 200mbs a sec over a 10gb ethernet connection in the beginning but sometimes it slows to 20mbs for no apparent reason and stays there.

    Is there a way to have it check or do an ack reset to re-negotiate the link speed through the switch?

    Reply
    • @Daniel,

      The slowness happens because of file encryption during transfer files over SSH, if you have that much of large data, you can reduce the encryption level or use other alternative tool like parsync (a rsync wrapper for larger data transfer).

      Reply
    • @Daniel, for the same reason, do I now run rsync as daemon server side, launched through xinetd. Now rsync can talk to rsyncd without ssh, and throughput went up considerably, while CPU load dropped.

      Security is of no concern in my case, as transfers take place in a trusted LAN, or go through a VPN – in which case I merely avoided double encryption, by SSH in addition to by VPN).

      A new problem was then introduced though, for which I have currently no proper solution – I wrote about this in another post just a few minutes ago in another comment here, asking for suggestions.

      Reply
    • @Daniel, regrettably I avoided addressing your actual issue: bandwidth limiting. Well, that’s possible with rsync running as daemon too, by use of the option –bwlimit=RATE. through this setting can you control the maximum amount of data transferred per time unit.

      Reply
  23. Thank you for the post.

    May I ask you if you may know how to setup a directory sync between two servers while using daemon running under /etc/xinetd.d/rsync.

    I target not to use just a command like in your examples, but to have xinetd running rsync in the background.. Samba.org examples of rsyncd.conf are not clear how to setup the path and the destination servers.

    Also in /etc/xinetd.d/rsync configuration there is no reference thus it is not clear if rsyncd.conf can be relevant and used at all. So how to make only two specific servers setup this way where one will be a source and another a destination, meaning that the content will be actively changing on one server, while another will get its folder just synced with the first one.

  26. Under RHEL 5.0, there is no argument called “–remove-source-files” instead there is a option called “–remove-sent-files”
    For example: If you are trying to copy the file to a local or remote system, you would use the following command.

    $ rsync –remove-sent-files -avzh /tmp/aziz.tar root@localhost:/tmp/backup1/

    Note: While specifying the destination directory, if the directory is not proceeding with ‘/’ it will create a file called /tmp/backup1. We need to ensure the directory ends with ‘/’ if we want to create the destination directory while runnning rsync.

    Hope it helps

  27. Thanks for this tutorial. I am a beginner in the server world and i find this quite useful.

    rsync -av [email protected]:/var/www/something [email protected]:/var/www/something

    is this going to work?
    also is there any option to run rsync command and then log out from my console (leaving rsync in progress). I need to transfer around 150GB and it would be great if i dont have to leave my terminal on.

  28. Hi, I have a request where I have to copy a directory(all of it’s files and sub directories inside it) to a destination. The destination will only have the top level directory. Basically, can I copy directories instead of files with rsync? If Yes, what happens if I run the same script with same ‘source’ and ‘destination’ again? Will it override what’s already exist in the destination directory?

      May be you’re wrongly mentioning files names. For example, the ‘Linux ISO’s’ directory should be called like this:

      So, call filenames with spaces same way as I showed above during rsync..

  30. Just want to confirm my understanding. If I issue the command from my source Linux server, “rsync -avzhe ssh /home/dir/ root@destn_server:/backup_Directory/”, all the directories and files of my source Linux Server under /home/dir/ would be copied to the destination server ‘destn_Server’ under ‘/backup_directory’ with the compression done on the fly. Is that correct ?

      Yes you correct it will archive and copy all the files and folders with hard links from source to destination directory on remote server.

  33. Want to use Rsync for process.

    To be more specific, I have a process where only designated files need to be transferred from a remote server to the local server. The local server will be will be fed a continual list (day-to-day) of files that need to be transferred from the remote server. Once these files are transferred to the local server, they do not need to be sync’d with the remote server. Any changes to the original file (remote server), would require another version release, thus a different file name.
    I am looking to be able to run a script on the local server that would receive the file input list, then compare against the files currently on the local server to see if resident or not. If file not on local server, transfer file from the remote server.

    Thanks for any help on this.

    Thank you for the post. it was really informative. My question is how do I synchronise Source Folder & a Target folder? Source Folder is been in Ubuntu and the Target folder is in Windows BUT mapped in to the Source Server as a local folder. When I use freesync it only copies the folders but not the contents. Push out an error stating file failed to sync cos its not permitted :( NOW when i do a basic copy and paste everything gets copied. Now I do not want to be doing that like a prayer would I ? So any help/Idea?. Thanks for your help in advance…..Have a good one

    • As a suggestion, you may want to emphasize that the `-e` option should often be followed by `”ssh -i /path/to/key/”` instead of just plain `ssh`. This is required for accessing an EC2 instance using AWS’s .pem keys, although I’m not sure when just `ssh` is used. Was the `ssh` following the `-e` just for the example?

    You get an end-user and a super-user edition of scripts that wrap rsync commands for the most common file backup and restore operations.

  46. There is a common confusion in your synching folders. It is one I frequently make and is a gotcha in rysnc. You MUST add the trailing slash, otherwise it will put the folder in your local folder, rather than sync the two:

    rsync -avzh /root/rpmpkgs /tmp/backups/

    will place the rpmpkgs in your backups folder. If you want to synch two folders that already exist:

    rsync -avzh /root/rpmpkgs/ /tmp/backups/rpmpkgs

    This for me is a very important little detail!

Example: podcasts located at http://213.215.116.181:8001/fm/DATE/FILENAME.mp3 where the DATE usually updates weekly, and FILENAME allways stays the same.

    or another nice option, especially if you’re syncing a VPS is the ‘–numeric-ids ‘ flag which will not map uid/gid by actuall user/group, for example:

    rsync -Waq -e ‘ssh -p ‘ –numeric-ids /path/to/source/ :/path/to/target/
