![]() ![]() It copies locally and to/from another host over a remote shell. rsync -azP mydir1 is a versatile and secure tool that streamlines file transfer and synchronization over TCP/IP networks. ![]() The two options can be combined as follows. The -z option compresses file data during file transfer thereby optimizing the bandwidth usage, while the -P option displays the progress bar. Other useful options that you can use with rsync are -z and -P. #Compress Files and See Transfer Progress ![]() rsync -av -delete mydir1 can confirm this by listing the files in the remote directory as follows. When the directories are synchronized, the missing files which have just been deleted in the source directory are also deleted in the destination folder to restore parity. In the example below, the files file1.txt and file2.txthave been excluded from the file transfer operation. To exclude multiple files, enclose them in curly braces separated by commas with no spaces in between. To exclude a specific file from being transferred, pass the -exclude option as shown: rsync -av -exclude=file source-directory/ destination-directoryįor example, to exclude file1.txt from being copied to the destination directory, we will run the command: rsync -av -exclude=file1.txt mydir1/ mydir2 #Exclude a Specific File From Being Copied Instead of using the -r flag, pass the -a option. The option syncs the files recursively and preserves file attributes such as file permissions, group and user ownership, modification times, symbolic links, etc. The entire directory is copied with its contents inside of it.Ī perfect alternative to -r is the -a( -archive) flag. Without the trailing slash, the rsync command copies the entire mydir1 directory as opposed to its contents.īelow is a snippet that shows what happens when the trailing slash is omitted. This implies that only the contents of the directory will be copied. Note the trailing slash ( /) at the end of the source file. If the specified destination folder does not exist, one is automatically created, and rsync copies all the data to it. The -r or -recursive option recursively copies all the files and subdirectories in a directory. The information displayed includes the files being copied and a summary of the total file size and bandwidth used. The -v or -verbose option prints out verbose output on the terminal detailing the file transfer process. To copy the files from mydir1 to mydir2, run the rsync command as follows. To confirm the existence of the files, run the ls command as follows ls -l Next, we will navigate into mydir1 and create 10 empty text files that we will later copy and sync to mydir2 which is the destination folder. The rsync syntax closely resembles that of other tools such as scp and cp.įor demonstration purposes we will create two directories mydir1 which will act as the source directory and mydir2 which will be the destination directory. The snippet below proves that rsync is installed. But just to be sure, you can confirm if rsync is installed by running the command: rsync -version However, as we have mentioned, it is pre-installed in most modern Linux distributions, and therefore, no installation is required. In addition, rsync needs to be installed on both systems. For the remote setup, we have the following lab environment: #Prerequisitesįor this guide, we will demonstrate file transfer and synchronization on both local and remote setups. In this article, we explore various ways you can use the rsync tool to transfer files and synchronize local and remote directories. Rsync is widely used for offsite backups and mirroring.īy default, rsync comes pre-installed on modern Linux distributions, and therefore, no installation is required. Rsync is a perfect alternative for the scp command which is now deprecated due to vulnerability concerns. Thus, it makes for a bandwidth-efficient tool and a sound choice for incremental data transfers. It uses a delta-transfer algorithm that sends only the differences between the source and destination files or folders. One must be a source and the other a destination, which may also be remote. Rsync, short for remote sync, is a file transfer and synchronization tool that securely copies and synchronizes files between two directories. ![]()
