This article focuses on "steps to install and use Rsync for synchronization on Linux". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn the steps of installing and using Rsync for synchronization on Linux.

For a variety of organizations and companies, data is the most important to them, even for e-commerce. Rsync is a tool / software that backs up important data over the network. It is also a network protocol for synchronizing folders and files between systems over the network on Unix-like and Window-like systems. Rsync can copy or display directories and copy files. Rsync listens to TCP port 873 by default and copies files via remote shell such as rsh and ssh. Rsync must be installed on both remote and local systems.

The main benefits of rsync are:

Speed: everything is initially copied between local and remote. Next time, only the changed blocks or bytes will be transferred.

Security: the transmission can encrypt data through the ssh protocol.

Low bandwidth: rsync can compress and decompress data blocks at both ends.

Syntax:

The code is as follows:

# rsysnc [options] source path destination path

Example: 1-enable compression

The code is as follows:

[root@localhost /] # rsync-zvr / home/aloft/ / backuphomedir

Building file list... Done

.bash _ logout

.bash _ profile

.bashrc

Sent 472 bytes received 86 bytes 1116.00 bytes/sec

Total 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

The code is as follows:

[root@localhost /] # rsync-azvr / home/aloft/ / backuphomedir

Building file list... Done

. /

.bash _ logout

.bash _ profile

.bashrc

Sent 514 bytes received 92 bytes 1212.00 bytes/sec

Total 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

The code is as follows:

Root@localhost /] # rsync-avz / home/aloft/ azmath@192.168.1.4:192.168.1.4:/share/rsysnctest/

Password:

Building file list... Done

. /

.bash _ logout

.bash _ profile

.bashrc

Sent 514 bytes received 92 bytes 1212.00 bytes/sec

Total 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-synchronize remotely to local

The code is as follows:

[root@localhost /] # rsync-avz azmath@192.168.1.4:192.168.1.4:/share/rsysnctest/ / home/aloft/

Password:

Building file list... Done

. /

.bash _ logout

.bash _ profile

.bashrc

Sent 514 bytes received 92 bytes 1212.00 bytes/sec

Total size is 324 speedup is 0.53

The above command synchronizes remote files locally.

Example: 5-find out the differences between files

The code is as follows:

[root@localhost backuphomedir] # rsync-avzi / backuphomedir / home/aloft/

Building file list... Done

Cd+ backuphomedir/

> f + backuphomedir/.bash_logout

> f + backuphomedir/.bash_profile

> f + backuphomedir/.bashrc

> f + backuphomedir/abc

> f + backuphomedir/xyz

Sent 650 bytes received 136 bytes 1572.00 bytes/sec

Total size is 324 speedup is 0.41

The above command helps you find the difference between the file or directory between the source address and the destination address.

Example: 6-backup

The rsync command can be used to back up linux.

You can use rsync in cron to schedule backups.

The code is as follows:

0 * / usr/local/sbin/bkpscript & > / dev/null

Vi / usr/local/sbin/bkpscript

Rsync-avz-e'ssh-p2093' / home/test/ root@192.168.1.150:/oracle/data/
