把 RPO 誤寫成 PRO, 猜測你可能不瞭解 RPO 三個字的意義....
(這裡不多解釋, 您可以去查備份名詞的: RPO, RTO, WRT, MTD)

網路傳輸雍塞也可能出現 RPO 違規, 即使他是備份成功的狀況:

RPO violations might occur for one of the following reasons:

- Network connectivity problems between source hosts and vSphere Replication servers at the target site.
- As a result of changing the IP address, the vSphere Replication server has a different IP address.
- The vSphere Replication server cannot access the target datastore.
- Slow bandwidth between the source hosts and the vSphere Replication servers.

你要先找出造成的根因, 方法如上所述:

Solution

- Search the vmkernel.log at the source host for the vSphere Replication server IP address to see any network connectivity problems.
- Verify that the vSphere Replication server IP address is the same. If it is different, reconfigure all the replications, so that the source hosts use the new IP address.
- Check /var/log/vmware/*hbrsrv* at the vSphere Replication appliance at the target site for problems with the server accessing a target datastore.
- Verify that you have sufficient bandwidth.
