We have nine computers in our office. They are all networked. On the "network" computer is where the tape drive is suppose to back up the complete (entire) system each day. We have 5 discs (one labeled Monday, one labeled Tuesday, etc). Every Monday at the end of the day, we insert the Monday disc for it to back up that night & take home with us the Friday disc. The next day we insert the Tuesday disc and take home the Monday disc. That way if the building was to be destroyed by fire, toronado or the computers stolen,etc. during the night, we have a back up disc we could purchase new computers the next day and keep operating. However, for several days now, it is not backing up each night. It is saying "Backup Failed". The discs we use are approximately 6" by 9" by 2" thick.
