She's only referring to your duties to not actively destroy evidence. If you have a regular expiration cycle for data, that's not a problem, unless you're informed you're being sued or otherwise investigated, at which point it's incumbent for you to turn off that process, and do whatever's necessary to continue to preserve the data. There are other reasonable things that can trigger the requirement to not destroy data. The only thing you would be required to prove, if you do lose such data, is that it was entirely accidental, and you didn't have any culpability. Say a tornado destroyed the office with the only set of paper copies, and it was reasonable for you to only have that one set.
