Love the term "data spillage"
Hmmm... "Data Spillage"... reminds me of an article from years ago which described how developers loved the term "bugs" as it conjured up an image of small things that crawled into your code - possibly overnight when no-one was watching - and that just had to be found the next day and removed. The suggestion was that if the term was "Massive F**k-Up" - or MFU for short - people would treat them a bit more seriously.
"Data Spillage" makes it sound like the sort of unavoidable - although regrettable - thing that happens when you copy data around. Ooops, just spilled a little bit of data, better just mop that up!
