When you have a web application that stores data in it's App_Data folder, at some point you'll want to synchronize the development environment(s) with the live environment. This way your development machine will have the latest live data. This is a task that can be achieved with git.
I have actually made the following work, but with the following adjustments:
- All involved Windows machines (development and live boxes) have Cygwin installed
- Windows live machine has Cygwin’s open ssh server running
Step 1 – Convert live App_Data into a git repository
The first step is to convert the App_Data on the live server into a git repository. This will be the source from which all other machines will fetch data from.
To do that, a simple way is to create a new empty git repository, add all existing files, commit and replace the old App_Data folder with the new git repository. Assuming you have a unix (Cygwin) shell, you can write something like:
cd /c/web/myapp mkdir NewAppData cd NewAppData git init . cp -R ../App_Data/* . git add * git commit -m "Copying existing App_Data" cd .. mv App_Data App_Data.backup mv NewAppData App_Data
At this point the App_Data folder is now a git repository containing all the existing data.
Step 2 – Convert development App_Data into a git repository
The second step is to go to the development environment and fetch the App_Data from the production server. Something like:
cd /c/projects/myapp mv App_Data App_Data.backup git clone ssh://my.live.server/c/web/myapp/App_Data App_Data
The local development machine now has a folder C:projectsmyappApp_Data that contains all the live data.
Step 3 – Keeping up to date
As the live server and the development machine continue to work on their App_Data folders, they will reach again a point that they need synchronization. To do that, first you need to commit the changes on the server:
git add * git commit -m "Blindly adding all changes"
Next, on the development machine you fetch the changes:
A bonus step can be automation. By creating scheduled tasks for the commit and pull steps you can stay in sync automatically.
Hope this helps.
