In theory, yes. In practice..... there are some operations, such as
dumping and reloading with large binaries or sensitive data excluded,
that are designed to *alter* history and clear undesired material This
can cause oddness if you have a linked slave, which is yet another way
to do backup. There are also operations that will, once a history is
corrupted, merely replicate the corrupted history. And remember that
the deprecated Berkeley DB logs from older Subversion environments are
not cross-platrofm compatible, so bringing those to another host can
cause trouble.
