This article will explain in detail how to use rsync under Linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Rsync is a commonly used Linux application for file synchronization, which can synchronize files between a local computer and a remote computer, or between two local directories (but does not support synchronization between two remote computers). It can also be used as a file copy tool to replace the cp and mv commands.

Syntax: # rsysnc [options] source path destination path example: 1-enable compression [root@localhost /] # rsync-zvr / home/aloft/ / backuphomedirbuilding file list... Donebash_logoutbash_profilebashrcsent 472 bytes received 86 bytes 1116.00 bytes/sectotal size is 324 speedup is 0.58

The above rsync command uses-z to enable compression,-v is visual, and-r is recursive. The above synchronizes between the local / home/aloft/ and / backuphomedir.

Example: 2-preserve the properties of files and folders [root@localhost /] # rsync-azvr / home/aloft/ / backuphomedirbuilding file list. Done/bash_logoutbash_profilebashrcsent 514 bytes received 92 bytes 1212.00 bytes/sectotal size is 324 speedup is 0.53

Above we used the-an option, which retains everyone and their groups, timestamps, soft links, permissions, and runs in recursive mode.

Example: 3-synchronize local to remote host root@localhost /] # rsync-avz / home/aloft/ azmath@192.168.1.4:192.168.1.4:/share/rsysnctest/Password:building file list... Done/bash_logoutbash_profilebashrcsent 514 bytes received 92 bytes 1212.00 bytes/sectotal size is 324 speedup is 0.53

The above command allows you to synchronize between local and remote machines. You can see that you are prompted for a password when synchronizing files to another system. When doing remote synchronization, you need to specify the user name and IP or hostname of the remote system.

Example: 4-remote sync to local [root@localhost /] # rsync-avz azmath@192.168.1.4:192.168.1.4:/share/rsysnctest/ / home/aloft/Password:building file list... Done/bash_logoutbash_profilebashrcsent 514 bytes received 92 bytes 1212.00 bytes/sectotal size is 324 speedup is 0.53

The above command synchronizes remote files locally.

Example: 5-find out the differences between files [root@localhost backuphomedir] # rsync-avzi / backuphomedir / home/aloft/building file list. Donecd+ backuphomedir/ > f + backuphomedir/.bash_logout > f + backuphomedir/.bash_profile > f + backuphomedir/.bashrc > f + backuphomedir/abc > f + backuphomedir/xyzsent 650 bytes received 136 bytes 1572.00 bytes/sectotal size is 324 speedup is 0.41 example: 6-backup

The rsync command can be used to back up linux.

You can use rsync in cron to schedule backups.
