SLP report

Hi All, 

We do some important backup using disk (Data Domain) then using the SLP this backup will be replicate over to anoghter disk (also Data Domain) to the other site. The auditor ask how we make sure that the replication is running fine? Did we check everyday (the SLP process?)

How do I check this? It is almost  possible to check one by one everyday, but it gives me soe idea:

1. Check the backlog during certain time when there is no backup using SLP running.
    Is it this method ok? I found some script that can do this (https://www-secure.symantec.com/connect/articles/n... )

2. Send the email when a replication using SLP failed?
   I don't know how to do this. 

Any idea?

Thank you

Iwan
