In case you need to reinstall your system and restore data, follow the instructions below.
The Recovery Image procedure deletes everything on the server, including existing data backups. If you intend to reuse any files, such as configuration files and data backups that exist on the server that you are going to do a recovery on, then you must transfer these files and data backups to another location (for example, to a USB memory stick).
In the following instructions the phases of waiting for the system to boot and transfer files are skipped. In some steps an estimated time is given.
