Creating a backup with the Linux rescue system

General

If you have an EUserv server or virtual server plan, you have the opportunity, via the customer service center, to start the server in the rescue mode.

With the function Rescue System you can connect to your server, even if a operating system installation was not successfull or the server is not accessible via the usual way. After the server has been started in the rescue mode, you can make a backup of your user- and configuration settings. This is a great necessity if your hard drive is defective or if the system and the software are no longer working and critical data needs to be protected.

Preparing and activating the rescue system

First, you have to boot your server or virtual server in the rescue system. How to do this, you'll find here.

Connecting with the rescue system

After your server or virtual server is booted in the rescue system, you can connect to your server using a SSH program (for example, Putty). Simply start Putty and enter the IP address of your server.

It is important that Port is set at 22 and Connection type: SSH is selected.
Now click on the button Open and the SSH connection to your server will be set up.

It appears a console window in which you are asked to enter your username and password. Here you enter your root and the default password of your server. Where you can find this information, you'll see here.

If you have successfully connected with your server in the rescue mode, the following window appears:

Create backup and backup the FTP server

In order to perform a backup of your user data and configuration data, you must create a zip file of your user and configuration files. These are located in the directories: /home,/etc and/var/www. This requires the following command to be entered in the console window of Putty:

tar cvf backup.tar /etc /home /var/www 

Now you can transfer this backup e.g., on a FTP server (we recommend our BackupHD/online hard drive Cloud). To do this, use the MidnightCommander (MC) with the following command:

mc

Now change to the directory where you saved the backup file (Default is the root directory), and select the backup file (backup.tar) by using the arrow keys:

In order now to connect with the FTP server, click on right and select FTP link ... with the arrow keys:

Now you are asked to enter your FTP server name and the user data. Fill in as follows:

The required data can be found in the customer service center: Cloud Now you can copy the backup file from your server to the FTP server. Choose File --> Copy:

Now the directory structure of the FTP spaces appeares on which the backup file should be copied. Confirm this with OK:

The backup file is now transferred to the FTP server.

Now you can connect with the BackupHD via the EUserv Web client: http://web.storage.euserv.net. After you signed in with your FTP user data, you will see your backup file.

You can download this by yourself. If a re-install of your server was necessary, later on you can transfer the data again to your server and unzip. You have restored ​​your user and configuration files.

Backup via rsync

Another way to create a backup of your files is using rsync. Here, the backup file will be transferred directly to your BackupHD/online hard drive. To do this, you can refer to the following wiki article:
