How to properly organize the transfer of changes from the dev server to the working one?

Question

Data synchronization

Such a question, customers often appear with requests to make changes on the site, and in order to avoid problems, I copy their projects to my hosting and make changes there. The essence of the question, how is the easiest way to transfer the project back later? Re-uploading all the files is not very desirable, and sometimes you have to change the database, Git also cannot be installed on my hosting, much less on theirs. And the work is sometimes long in time and remember where what changed, also not an option. How are you doing?

Answer 1

rsync might work for you

Answer 2

Get yourself a local git (I advise gitlab right away), set up jenkins (you can also use gitlab ci, I haven’t tried it), so that you can monitor and distribute changes to production yourself. You make a blank of settings that you propagate for all incoming new projects and old ones that you return to.
