Well i got a massive grief by a hacker, and i need to unzip my backups, how to do it in winscp remote?
I've only done it the hard way... download it, unzip, and then reupload the world (which could take a few hours depending on world size and connection)
Get something like McMyAdmin, you can restore backups with a few clicks. Also get somthing like logblock and then this issue wont be a big deal
