I’m currently use copr to do some personal Fedora packages in copr website. so I wonder the storage limit of a copr projects?
I went fast over the manual and not could see a specific number about a limit.
But in the FAQ it is listed what you can do within copr.
User Documentation — COPR documentation
Considering how huge the Google Chrome build stuff is that existed on copr, I believe the storage capacity to be ample for most things.
