This opsi extension is developed especially for schools, to restore the software of the students clients during the break.
An image of the initial installation of a client is stored in a special partition on the local client. This image can be used for a quick restore. The system Administrator can trigger the backup and restore with the switches 'image backup' and 'image restore'.
The local storage of images allows many clients to be restored at the same time, without blocking the local network. (The sale of this extension is restricted. Please ask for an offer).
