How do I create a branch in SVN?
如何在SVN中创建分支？
Branching in Subversion is facilitated by a very very light and efficient copying facility.
Branching and tagging are effectively the same. Just copy a whole folder in the repository to somewhere else in the repository using the svn copy command.
Basically this means that it is by convention what copying a folder means - whether it be a backup, tag, branch or whater. Depending upon how you want to think about things (normally depending upon which SCM tool you have used in the past) you need to set up a folder structure within your repository to support your style.
Common styles are to have a bunch of folders at the top of your repository called tags , branches , trunk , etc. - that allows you to copy your whole trunk (or sub-sets) into the tags and/or branches folders. If you have more than one project you might want to replicate this kind of structure under each project:
It can take a while to get used to the concept - but it works - just make sure you (and your team) are clear on the conventions that you are going to use. It is also a good idea to have a good naming convention - something that tells you why the branch/tag was made and whether it is still appropriate - consider ways of archiving branches that are obsolete.
Subversion使得它很容易（有些人认为太容易）使用svn copy命令创建一个新的分支。
$ svn copy svn+ssh://host.example.com/repos/project/trunk
svn+ssh://host.example.com/repos/project/branches/NAME_OF_BRANCH
-m "Creating a branch of project"
svn cp /trunk/ /branch/NEW_Branch
如果您在中继中有一些本地更改，请使用Rsync同步更改
rsync -r -v -p --exclude ".svn" /trunk/ /branch/NEW_Branch
