I don't recognise that backup format, but I assume (hope?) that it is just because of differences between distro's. I'm on Ubuntu and mine are formatted as "mythconverg-1317-20140130055001.sql.gz" ie mythconverg-schema-date. It's probably just me but the '.pl' extension on yours seems very odd.... Did you say you were on Gentoo? Maybe someone else on Gentoo could confirm. To be honest I kind of thought that the (default) format was distro-independent however....
