You can do this in a easy way your self.
alias backup {
if ($isfile(mirc.ini)) { .copy -o " $+ $mircdir\mirc.ini $+ " " $+ Path $+ " }
}
Path should be replaced with as a example. C:\backup , and make shure the folder you copying from exist. For a time you can look at /help /timers . Or you can use the backup every time you closing mirc, take a look at /help on exit
Add the code to your remote. ALT + R in mirc. And you trigger it with: /backup
