This will at least backup your files( *.ini and *.mrc) each time you open mirc for you.....then you are no more than a day out...

on 1:Start: {
if $exists($mirc $+ backup) == $false { /mkdir backup }
Set %backup.mrc $findfile($mircdir,*.mrc,0, .copy -o " $+ $1- $+ " " $+ $mircdir $+ backup\ $+ $nopath($1-) $+ ")
Set %backup.ini $findfile($mircdir,*.ini,0, .copy -o " $+ $1- $+ " " $+ $mircdir $+ backup\ $+ $nopath($1-) $+ ")
}

Hope it helps
