在centos（vps）中的特定目录中还原已删除的文件

我不小心删除了/etc/yum.repos.d目录中的所有文件

yum repolist all
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repolist: 0

yum install svn
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
There are no enabled repos.
  Run "yum repolist all" to see the repos you have.
  To enable Red Hat Subscription Management repositories:
     subscription-manager repos --enable <repo>
  To enable custom repositories:
     yum-config-manager --enable <repo>

如何还原特定目录的文件？
