All databases require special backup handling, since their files must be
maintained as atomic units (as opposed to individual files like CVS). You
should read through the book, here:


for different ways to maintain backups. In fact you should probably read
through the whole book before proceeding much farther...

No, you are confusing "access" with "permission" in this case. Even nominally
readonly operations require write access (this is true of most databases that I
am aware of, for temporary tables, etc.), but you can limit permission to write
new revisions through various means. The easiest is probably authz_svn_module,
see the book here:


You can also use svnserve and provide r/o and r/w users, but the support is much
more limited:

See the documentation for TortoiseSVN, but in general, you would only see
something on the context sensitive popup menu (Right Click). If you want
something more comparable to WinCVS, you should check out RapidSVN instead of
