During a server migration for our web based file sharing system our lead engineer (at the time) forgot to ensure that all cron jobs (for cleaning up files and sending out automated emails) had been turned back on. Queue me 7mos later reviewing the system. Realizing that critical jobs were no longer running and that our users were all essentially receiving 100% free hosting for however much storage they wanted. SOOOO i turned the jobs back on. The lead engineer before me left no documentation of what the jobs did other than that they should be run. In my stupor i did not review the code. The jobs sent out a blast of emails warning that files would be deleted if not cleaned up or maintained. Then seconds later deleted said files... We nuked around 70GB worth of files before we realized what happened. WELL GET THE TAPES! Turns out our lead engineer ALSO forgot to follow up w/ system engineers and the backups were pointed at the wrong storage. No jobs lost, thankfully the manager at the time was a word smith of the highest degree and can play political baseball like a GOD.
