Untested backups with "experts" relying on them (and other "experts"' assurance that everything would work if needed). The worst thing _I_ have actually seen in reality was (many years ago) a customer who's "professional consultant" had messed up the backup process so nothing was written to the tapes, and nobody had checked the logs, so the customer ended up with a box of blank tapes; the box was labeled "BACKUP". You can imagine how "satistied" the customer was with his expensive "service" when the worst case happened, disks crashed, and he would just have to restore yesterday's backup... :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
