I heard a good story from an ex-Telecom guy here. Apparently they'd upgraded the software on an exchange and everything appeared to be going normally for several months, until one day when the whole thing turned to custard (crashed). It was so bad that they had to restore the system off their tape backups. What they didn't realise is that the software upgrade had a bug which was writing corrupt data to the tape. They keep about 6 months worth of tapes and they were all stuffed as the upgrade had been done a long time beforehand. All the data had to be re-entered by hand from written records. You can never be too paranoid about your backups... - Dave http://www.digistar.com/~dmann/ (out of date) - This message is from the Pentax-Discuss Mail List.
