Save my files to my BackupHD with rsync
Activating of rsync

Connecting to Online Storage via rsync
Creating connection to Online Storage via rsync
To establish a rsync connection to Online Storage, enter the following command:
rsync [user]@[server]::[module]
[user] - your FTP account
[server] - in case of Online Storage e.g. rsync1.euserv.de
[module] - your FTP account
Hint: Your FTP account must be entered twice to ensure your FTP account has the access for the corresponding rsync module.
Encrypting of rsync connection via SSH
To encrypting the data transfer via SSH connection, enter the following command:
rsync -e ssh [user]@[server]::[module]
[user] - your FTP account
[server] - in case of Online Storage e.g. rsync1.euserv.de
[module] - your FTP account
-e ssh - use SSH connection
If you use the connection via SSH you must entered your password twice. Once for the connection via SSH and once for the rsync connection.
Alternative: Rsync via stunnel
Examples
1. Simple command to backup of EUserv Online Storage:
The file /etc/resolv.conf ahould be saved in folder /backup/ on your server.
rsync /etc/resolv.conf -e ssh --progress ftpbackup-1234@rsync1.euserv.de::ftpbackup-1234/backup/
--progress - This parameter shows a progress bar of the transfer.
2. Incremental backup
The folder /var/www/ should be completely saved on the Online Storage.
rsync -avuzR -e ssh /var/www/ --progress ftpbackup-1234@rsync1.euserv.de::ftpbackup-1234
-a Archie Mode - receipt of file attributes
-u update - overwrite files, if they are newer
-v verbose - extended output
-z compress - compression to save bandwidth
-R relative - uses the full path on the server, the backup will be created in the folder /var/www/ on the server (without -R in the folder /www/)
3. Backup without password
If you use the parameter "--password-file" you can use rsync, without entering the password by every connection.
If you want to use SSH encrytion, the tool sshpass will be needed.
Install sshpass on your server with the following command (for Debian):
sudo apt-get install sshpass
sshpass can be alternatively compiled. http://sourgeforge.net/projects/sshpass/
Create a new file, which includes the password for rsync e.g. /root/rsync_pass. The file should be belong to the user which runs the rsync command and has the user-rights 700.
The backup progress is taken place with the following command:
sshpass -f /root/rsync_pass /usr/bin/rsync -e ssh --password-file /root/rsync_pass [directory] [user]@[server]::[module]
For more information:
man rsync
Enabling key-based access for rsync
To set the SSH key for rsync connections, proceed as follows:
- Log in to the customer panel under http://support.euserv.de with your customer ID and your password.
- Choose Contracts from the left menu and select your Online Storage contract.
- Click on Verwaltung.
- Click the Ändern button in the view FTP-Backupserver Konfiguration.
- Enter your SSH key under öffentlicher Schlüssel zur Authentifizierung über OpenSSH in the following format: ssh-rsa<base64 coded array>[= <username>@<host>].
- Finally, click the Save button.
Your SSH key has now been set for the rsync connection.
