Restore an existing backup

Hello,
I am under Debian 7 and I have a problem with ispconfig3.
In fact I would like to know how to restore ispconfig3 from an existing backup that is located in /var/backup/ispconfig_2014-12-07 on my server.
In the "ispconfig_2014-12-07" folder there are:
- etc.tar.gz
- ispconfig_db_backup.sql
- ispconfig_software.tar.gz

Thank you very much for your answers!

 

In fact I followed the tutorial "The Perfect Server - Debian Wheezy ( Apache2 , BIND, Dovecot , ISPConfig 3) " to the end and everything worked well.
Except now I have added additional versions of PHP ( 5.6.6 and 5.5.22 ) and I think there was a mistake because ispconfg no longer appears at: https://mydomain.com : 8080 / and I do not have access to phpmyadmin via the link https://mydomain.com:8080/phpmyadmin
The page displays "Connection failed" [status: Aborted] .

Thank you for your response.

 

thank you for your quick response
However, I have the following error when i run the command:
--------------------------------------------------------------------
Some packages could not be installed. This may mean that you have

the error persists...

I don't know where is this file but if you tell me the link to access I can stick its content here

 

here is its content:
deb http://ftp.debian.org/debian wheezy main contrib non-free
deb http://security.debian.org wheezy/updates main contrib non-free
deb http://packages.dotdeb.org stable all
deb-src http://packages.dotdeb.org stable all
deb http://packages.dotdeb.org wheezy-php55 all
deb-src http://packages.dotdeb.org wheezy-php55 all

 

OK, I launched the command and now by accessing the page https://mydomain.com:8080/
I get an error 500 [Internal Server Error]

 

but the logo is displayed in the browser tab
it's a good sign

 

Can you give me the links to access these 2 files please ?
thanks.
