What do you mean, "or not"? Why would you care how Subversion keeps
your data safe? Isn't it enough to know that it does?

I believe it was just last month that there was a discussion on this
mailing list about what benefits people percieved by using an SQL
backend. You can look it up in the archive if you like, but suffice
it to say the topic has been brought up several times before, but in
the end, the answer is that Subversion can't do that right now, and
it's not a developer priority right now because it's not clear what
the benefits are over the current implementation, or that the
benefits, if there are any, justify the development effort, when
perhaps the benefits can be achived in other ways, sometimes through
other tools which already exist.

I still can't quite get a mental picture of what that really means. I
can tell you that most people have a repository server and then have
working copies on their local machines, do work, test it, then check
it in when it works. This works well for many kinds of work, such as
compiled software applications or non-programming collaboration. In
our company, we develop PHP/MySQL web sites, so we happen to put our
working copies on a central server which is set up with Apache and
MySQL, and our users access those working copies either via a Samba
mount on their Windows machines, or via an SSH session to the server
over the command line.
