        It seems a couple of tools might be needed.
        1. Cheap verification. Most likely achieved by supporting
verify revision ranges so that recent revs can be verified to detect
errors earlier. This sounds like it's on the way.
        2. Repo scraper. A dump option that dumps revisions while they
good, skips revisions when they're bad and keeps content in subsequent
good revisions that is recoverable - eg skips rather than diffs. Let
users know revision timestamp info to suggest that some or all data
newer than these times is missing.
        Cheap verification dramatically reduces the urgency of providing
what could be a fairly complex recovery tool.
        If repo content can be verified more often then users will get
more opportunity to use their backups productively.


The above would be great. Where a revision has corrupted, that hasn't
stopped us from being able to check in a subsequent revision of the same
code in the same part of the svn tree. SVN is clever enough to allow
you to check in again and successfully update the revision on top of the
broken one. It's only the one revision which is broken so I wouldn't
expect the revision tree for a particular file to be removed just
because one of its revisions was corrupted.
