The regular benefits of Day One vs. the possibility of losing an entry

I’ve written this basic thought before, but anyway: I’ve never personally lost data (that I know of) with Day One, and I freak out periodically at the thought of any entries getting corrupted or zapped. The sysadmin in me says, “losing data must not happen”. But more often than the freak-outs, the “On This Day” feature pops up a photo combined with some forgotten thing I captured a long time ago that delights Sarah and me, either because it’s funny or touching, and that seems like enough of a reason to keep using it, hope for the best, and export everything to PDF every so often.
