Remote Automatic Backup rsync + SSH + sshpass

Feature: automatic backup between remote servers

Most O & M personnel know the advantages of rsync backup. Simply put, only modified files are backed up to reduce the amount of data transmitted. At the same time, it can transmit data through the SSH protocol for data security.

However, SSH has a disadvantage. Only the password can be entered in interactive mode. As a result, the backup program cannot be written to crontab and can only be executed manually. Automatic batch processing is not supported.

Sshpass can decrypt this disadvantage. Let's take a look:

: Http://sourceforge.net/projects/sshpass/files/

Decompress the package./configure; Make; make install to complete the installation.

Usage:

Sshpass-P 'Password' rsync-AV-e SSH localdir username @ remoteaddr:/remotedir or

Sshpass-F password. File rsync-AV-e SSH localdir username @ remoteaddr:/remotedir

Password: Remote Server Password

Password. File: the password file.

Localdir local directory to be backed up

Username Remote Server Username

Remoteaddr Remote Server IP address or remote server Domain Name

Remotedir remote server path

PS:

The Rsync exclusion directory syntax is -- explode = directory name. In actual tests, the directory name cannot be an absolute address.
