Madhan S,

I have tried all of the steps from within this article and have not been able to have the protected servers appear when I try to enable secondary protection of another DPM server. I will explain...

We have two sites (Central site and North site)each with a DPM protecting the servers within each site, I have successfully configured the DPM on North site to protect the replicas of the DPM on the Central site.

I have deployed the agent from the Central DPM to the North DPM and it shows OK status but when I try to enable secondary protection it displays 0 protected servers? I have scoured the web for some ideas of what I may or may not be doing correctly and am out of ideas. I did find a few articles relative to using a DPM that was previously doing secondary backup and having to contact microsoft support to have them modify some SQL data table entries but thats all. Any help or advice would be greatly appreciated.

Major Fix required for DPM sp1

I have one DPM box at Head Quarter site and another at DR site and secondary protection is enabled.

The DPM that directly takes the backups with 15min deltas is working fine but the DR DPM which is serving as secondary protection is having a strange problem.

At certain point in time like after 1 day or so, recovery points stop getting populated, although although status is shown as green ! If manual recovery point is created, all works fine except that the new recovery points taken from primary DPM server are not updated in the list and thus cannot be selected !!!

I have two hotfixes also applied that are applicable since SP1.(KB963102 & KB968579) for 32bit installation.

This is very misleading as through all the notifiactions and alerts everything is working as OK status but underlying there is such a big problem and right at the time of disaster you cannot have the last recovery point available !

The primary DPM is working fine, with all the recovery points getting updated right after 15 mins. But at teh DR site, after 6 hours, when it goes for replication, it does that successfully but the recovery points are simply not enlisted in GUI.

This is very very disappointing.......! as right at the time of disaster you only have to option to do recovery either from primary DPM or do a complete resync for all data from primary DPM which renders the whole solution as useless for WAN !

Machine is also updated to date (windows 2003 sp2).
