1. 全量备份原始SVN库 - master
   svnadmin hotcopy repos/ repos.bak

2. 将master上的备份库拷贝到slave - slave
   scp -r root@IP://home/svn/pon/repos.bak repos

3. 创建slave机库 - slave
   svnadmin create /home/svnbak/NEW_PON
   cp /home/svnbak/NEW_PON/hooks/pre-revprop-change.tmpl /home/svnbak/NEW_PON/hooks/pre-revprop-change
   vim /home/svnbak/NEW_PON/hooks/pre-revprop-change将最后一行的exit 1修改为exit 0
   chmod 755 /home/svnbak/NEW_PON/hooks/pre-revprop-change
   svnsync init file:///home/svnbak/NEW_PON svn://IP --username xxxx --password xxxxx

4. 备份slave机库并重命名从master机上拷贝的库
   mv /home/svnbak/NEW_PON/ /home/svnbak/NEW_PON.bak
   mv /home/svnbak/repos/ /home/svnbak/NEW_PON
   注意将目录命名为slave机上创建库的名称

5. 拷贝slave机原库的一些文件到新库
   rm -f /home/svnbak/NEW_PON/hooks/pre-revprop-change
   cp -f /home/svnbak/NEW_PON.bak/hooks/pre-revprop-change /home/svnbak/NEW_PON/hooks/pre-revprop-change

rm -f /home/svnbak/NEW_PON/db/uuid
cp -f /home/svnbak/NEW_PON.bak/db/uuid /home/svnbak/NEW_PON/db/uuid

rm -f /home/svnbak/NEW_PON/db/revprops/0/0
cp -f /home/svnbak/NEW_PON.bak/db/revprops/0/0 /home/svnbak/NEW_PON/db/revprops/0/0

6. 查看slave新库所对应的最新版本号
   cat /home/svnbak/NEW_PON/db/current获取master库热备份时的最新版本号
   svn propset --revprop -r0 svn:sync-last-merged-rev 41675 file:///home/svnbak/NEW_PON

7. 执行同步
   svnsync sync file:///home/svnbak/NEW_PON
   cat /home/svnbak/NEW_PON/db/current获取当前slave机新库的最新版本号，看看是不是已经同步了

8. 添加crondtab定时任务，ok
