If you make some wrong changes in the configuration file, it will cause the associated service to crash. + +So it is a good idea to take a backup of configuration files, and you do not have to worry about disk usage as this not consume much space. + +### What does this script do? + +This script backs up specific configuration files, moves them to another server, and finally deletes the backup on the remote machine. + +This script has six parts, and the details are below. + + * **Part-1:** Backup a General Configuration Files + * **Part-2:** Backup a wwn/wwpn number if the server is physical. + * **Part-3:** Backup an oracle related files if the system has an oracle user account. + * **Part-4:** Create a tar archive of backup configuration files. + * **Part-5:** Copy the tar archive to other server. + * **Part-6:** Remove Backup of configuration files on the remote system. + + + +**System details are as follows:** + + * **Server-A:** Local System/ JUMP System (local.2daygeek.com) + * **Server-B:** Remote System-1 (CentOS6.2daygeek.com) + * **Server-C:** Remote System-2 (CentOS7.2daygeek.com) + + + +### 1) Bash Script to Backup Configuration files on Remote Server + +Two scripts are included in this example, which allow you to back up important configurations files from one server to another (that is, from a remote server to a local server). + +For example, if you want to back up important configuration files from **“Server-B”** to **“Server-A”**.
