Snapshot stalls when backing up media – symlink / capistrano issue?

I am trying to get Snapshot to work with my current deployment setup. I’m using capistrano to deploy code updates to my site. I wonder if Snapshot is hanging on the media portion of the backup because my uploads directory is symlinked to a shared directory that doesn’t get overwritten on subsequent deploys.

So, the shared directory is here where all uploads are stored:


Here’s the symlinked dir in the current deployment of the site

/home/mywebsite/public_html/releases/20121025005635/wp-content/uploads -> /home/mywebsite/public_html/shared/wp-content/uploads/

Does this seem like the problem? Any suggestion on a fix?
