svn 备份后双机同步热备失效，提示 W200007 target server does not support atomic revision property edits; consider upgrading it to 1.7 or using an external locking program
svnsync: E170009: Repository UUID 'xxxx' doesn't match expected UUID 'yyyyy'
解决方式：
step 1 先查看当前svn版本库的UUID:
svnlook uuid SVNRepoPath #结果应该是 'xxxx'
step2 使用svnadmin修改当前版本库的uuid
svnadmin setuuid SVNRepoPath yyyy #将无法同步版本库的UUID设置为原来的UUID 'yyyy'
step3 再查看当前svn版本库的UUID
svnlook uuid SVNRepoPath #结果应该就是 'yyyy'了
此时再执行svnsync --none-interactive destUrl --username USERNAME --password PASSWORD
就可以正常更新了。
