Telecom NZ once installed a software upgrade in one of their exchanges. Everything went fine for several months, until something caused the thing to completely fall over and lose all its data (which phone number goes on which wire, and all that kind of stuff). They grabbed the most recent backup tape and found it wouldn't read. So they fished out the next most recent tape , which was faulty as well. They keep about 6 months worth and eventually they discovered that the whole lot was no good. They had to re-enter all the data by hand. Luckily it wasn't a very big exchange but it still took a while. It turned out that the software upgrade had a bug which hadn't been discovered during testing. This bug caused corrupt data to be written to the backup tapes... Cheers, - Dave http://www.digistar.com/~dmann/ (out of date) - This message is from the Pentax-Discuss Mail List.
