title: A way to copy files from one Caprover image to another
body: <p>I uploaded a website using caprover and django and works well. Everything works fine, but I noticed whenever I updated the project user files get lost, although everything gets updated quite well. I understand caprover is build on top of nginx and docker, but I'm new to them.</p>
  <p>Every time I update caprover it builds a new image( I guess docker image) and this makes user images to disappear (I guess left in the previous image) is there a way to copy those files? Thanks in advance</p>
