comparing different subversion respositories

subversion 1.4.2

We have a repository. We are going to back up that repository to our server. However, our customer wants to know that if we were to restore that repository, how do they know if someone has tried to change something or do something bad to that repository.

We will keep the 开发者_开发知识库repository on our development server. And backup that repository to our backup server.

How can we confirm that both repositories are exactly the same?

Many thanks for any suggestions,

A possible solution is to use svnadmin dump for backuping. Then you can calculate MD5 or other hash sum on the dump files and compare them.
