With something like this, how do you handle the period of time while copying? I mean you can’t really leave it running as it wouldn’t be in a consistent state. A “under maintenance” page instead? Copy to a fresh folder and when done tell the webserver to serve the new location?

It depends. I’ve done it a few different ways:
- YOLO: especially with thugs like PHP you only affect one page at a time and with low traffic the odds of a problem is small
- Maintenance page: temporarily show a page. Some servers like IIS have this built in. Otherwise it’s a simple update to httpd conf
- In a cluster environment, just take the node you’re updating out of rotation, and only update one node at a time.
- Copy and switch like you suggested. Can be combined with any of the above and is a smart move if upload is slow or can be interrupted, or it’s cumbersome to restore the old files
Edit: spelling
