A couple of years back I was in a meeting with a few colleagues from the IT department, and a non-technical IT manager from another department. We were discussing DR options for their servers, in particular mirroring a fairly large, but mostly static, set of documents across onto another server. I suggested using rsync, and went on to explain it, but kept getting a slightly odd look from this other manager everytime I mentioned the word "rsync". Halfway through the meeting it finally dawned on me, she probably thought I was talking about "arse ink".
Ever since that meeting, it’s almost impossible for anyone to mention rsync without at least one of use bursting into fits of laughter.
Rsync, a useful tool eternally corrupted by a misinterpretation.
