Generated binaries and version control

I need an opinion: Should I put the generated binaries included in the update in the step 1 of the "New release workflow" (http://wyday.com/wybuild/help/workflow.php) in version control? Only update files and client.wyc? In case that not, can I continue releasing updates if I lose that files?

You should always backup your original binaries. Whether you do that with version control or with a properly configured NAS (network attached storage) it's entirely up to you.

In case that not, can I continue releasing updates if I lose that files?

If you lose the original files you will no longer be able to generate patches from those old versions to the latest version of your app.

Thank you, very clear!
