Re: Lack of Subversion repository recovery tools

The problem is that hardware faults and errors don't just occur on the
server side where you have significant control over them - they can often
occur on the client as well.

I experienced a situation where a repository of another SCM tool was
corrupted because the client network driver was erroneously inserting
nulls into files while they were being transferred across the network.

We were initially unaware of the issues because the SCM solution was
(correctly) recording the contents of the files which were being presented
to it as the new revision and developers were going on continuing their

Eventually (a week or so later) they were unable to modify the objects
which had become corrupted. Fortunately the SCM system had tools for going
through the repository identifying the components which were corrupted and
then recovering their contents appropriately.

If you're in a job where you're able to turn around to management and say
"sorry we've lost the last week's worth of development & it'll all just
have to be done again because our SCM system doesn't let us fix things"
then you're in a position of real power.
