Thank you for your comments, Andreas:

I am going to prevent this by means of `svnadmin verify':

Then I propose the following strategy:

1. Maintain a repository mirror by calling
     svnadmin hotcopy --incremental
   from a post-commit hook.

2. Store the last verified hot-copy in an archive:

   a. make a hot copy of the mirror

   b. verify this secondary hot-copy in order not to lock
      the mirror for a long time,

   c. archive the secondary hot-copy in a format with error-
      correction, such as .rar. I haven't found a free,
      stable, and easiliy available archiver with built-in

Of course, my script will notify the administrator of errors
at any step.

Please, do not forward replies to my e-mail.
