Lost project after gateway restore

Our project team was having bug issues, we upgraded Java and Ignition to the most recent versions. We had gateway problems and had to restore a backup. When we restored the gateway the only projects that we can find were the ones created before the restore point.

Are our most recent projects gone for good, or is there a way to get them back? I was able to find the jnlp of the missing projects, but not the missing project files themselves.

Any help will be appreciated, thanks.
