You did WHAT?
Had a call from the US one day. The woman on the other end of the phone complained that she was unable to start an Oracle database that contained a lot of critical company data. Going through the logs, it appeared that the database files were missing. My first thought was filesystems not mounted. Nope - they were good. Went through the directory structure and found..... nothing.
In a small voice, the woman then admitted that the filesystem had become quite full, and that she'd cleared down some 'large files'. Worked out that these just happened to be the database files!
She asked if I could 'undelete them'.
I told her to restore the last good backup.
She told me that that was three weeks ago........
