I am using Eclipse, salesforce, and git. In Eclipse, when I do force.com -> Refresh from Server selecting all items from my salesforce server, am I also including my skuid pages? If so, how can I use the backup copies of my pages placed in my GIT repository? In the background is also running GIT to save all the files included in my salesforce project.
Unfortunately no you’re not including skuid pages because skuid pages are records and records are not metadata. Eclipse using the Force.com plugin is only capable of pulling metadata as defined by the Tooling API (for example).
The closest thing you may be thinking of is being able to edit and deploy Visualforce pages in such a manner. Being able to version and edit skuid pages in such an IDE requires a different workflow/deployment process.
