DiskSafe的configuration file是 /usr/local/falconstor/disksafe/etc/disksafe.cfg ，他是一個XML檔，我們以僅有一個sdd protection policy (其mirror disk為sde)例子來看:

以下說明它的結構:

<disk>標籤是用以紀錄disk的狀態，包括partition、devicePath、 mountPoint、 capacity、 diskID、scsiAddress等等。如果這個disk又是來自CDP server的話(通常是mirror disk)，就會有 server、 maxSnapshots 、 protocol 等資訊。

<protections> 標籤是用以紀錄protection policy的狀態，包括 id、groupName 、umapDiskID 、 hostName、createTime 、 storage、options 、 schedule等等資訊。
