"I'm calling from R&D Minneapolis. Our server had a worm that infected the whole department. We had to install the operating system again and then when we went to restore from backup, none of the backups was any good. Guess who was supposed to be checking the integrity of the backups? Yours truly. So I'm getting yelled at by my boss, and management is up in arms that we've lost the data. Look, I need to have the latest revision of the source-code tree as quick as you can. I need you to gzip the source code and send it to me."
