Where are the saves located? I an searching a lot and nothing...

EDIT : From bloodlines and with GOG Galaxy. I wanna backup my saves and sync won't work(always fails by some reason)

Vtmb saves are huge. I am near the end of the game and my saves take 300mb space. And gog cloud saves only allow 200mb per game. So I have to transfer them to my second pc with a usb drive

Interesting, have you perhaps modded the game? I'm asking because I don't think this is normal with the vanilla version of the game, however I played it long ago.
Anyway thanks for sharing.

I'm always amazed how people happily trust the cloud.

You literally have no reason whatsoever to. There is no guarantee of any kind. If something happends, well, that was it.

So transfer from A to B is all its good for.

Want to keep it ? Hold your own copy, with multiple backups.

Want to never see it in other hands ? Never put it in the cloud in the first place. Or only in encrypted form. With a secure encryption. And a good password.

I wish it was vanilla. But the gog game comes modded nowadays. I didn't add any mods.

... and the Unofficial Patch, which is installed by default in the GOG release, can be removed using this patch.

There is no need for this. As written above, starting the game via the legacy shortcut runs the original game with only engine fixes like widescreen and more than 2GB RAM support. If you don't even want these, just rename all files with the extension 12 included in both patch and GOG release, which are the original 1.2 patch backups.
