On could get it practically fail safe, by having 2 different files. After any
move, alternate overwriting one of those with the current
move-list/PGN/whatever. The 10 msec or so overhead for each move would be
totally unsignificant for typical time controls in
"human-operates-on-a-real-board-tournaments".

Of course, one could argue, that a power failure may corrupt your whole HD, but
then probably typing in the moves manually is the least problem ...

BTW, concerning UPS. The operator of Yace at the Leiden 2002 tournament told me,
that in the game Isichess-Yace sombody walked over the cables and umplugged
them. I guess, something like this can hardly be avoided in general.
