Last sunday was a bad day. The system disc of our main server decided the break down with a complete data loss.
The good thing: Our provider exchanged the disc the next day.
The bad thing: We had to reinstall the system.
The good thing: We had a backup of the data.
The bad thing: The backup was from saturday. So the data from one day is lost.
The good thing: The revocery of the data worked well.
The bad thing: It took more than 24 hours to copy everything to the new server. Yes, we have a lot of contents. ;-)
