Typically sieve files/directory/symlinks would be stored below this point.

Maildir.

You have two items: home, and maildir.
If you copy the maildir, you have everything, except for anything else 
that dovecot might be storing outside the Maildir, in the home 
directory. This would typically be sieve stuff, as mentioned. Take a 
look and see. Review your config etc.
But in terms of what you specifically asked - just keeping track of 
messages and their flags, it's all within the Maildir, positive.

The Maildir does not need to be a subdirectory of the home directory, 
this is just my example.

One other thing that is possible in dovecot is separate storage for 
indexes, but if you're doing that, I would think that you should know 
you are :-)
