how to restore plesk configuration if filesystem is damaged?

[tape]

We need help immediately because our server filesystem was severely damaged.

We can recover some important folders from filesystem (/var/lib/mysql, /var/www, etc) and we believed that it should be able to restore configuration after new fresh installation.

So could anyone please assist us to restore plesk configuration in this situation.
Right now we need more details about other folders that use to store data (other than /var/lib/mysql and /var/www/). And detailed instruction to reinstall and restore plesk configuration using recovered folders from filesystem instead of plesk backup.

Thank you
