Rsync builds a Disaster Recovery Backup System

Assume that there are two linux systems A as the server and B as the backup machine. You need to install rsync software on Ah AB to run the rsync daemon on system, system B regularly backs up data specified by system A through the crontab daemon to implement data backup.

Server Configuration
1. Run the command to check whether rsync is installed.

2. Modify the rsync configuration file (rsyncd. conf)
The rsync configuration file is/etc/rsyncd. conf. By default, this file does not exist. Just create one manually. The rsyncd. conf file contains one or more modules, including global parameters and module parameters. The definition of a module starts with the module name in brackets.

Uidgid the ID that the daemon should have when the module transfers files
Maximum number of concurrent connections of the maxconnections Module
Strictmodes specifies whether to check the permission of the password file. If it is set to yes, the password file must be root. Therefore, you must modify the permission of the created password file. Otherwise, an error is reported.
[Test] test is the module name.
Path specifies the data to be backed up
Ignoreerrors ignores unrelated I/O errors
List whether the module is listed when a customer requests that the module list can be used
Account used for vauthusers connection Verification
Secretsfile Password File Format Username: Password
