Even though I operate what is essentially a one man shop, I use System Center Data Protection Manager 2007 (DPM) to protect my data. Although my DPM server has been working relatively well for quite some time now, I have been getting a lot of errors lately due to inconsistant replicas.
I spoke to someone at Microsoft about the problem, and they asked about my server’s hardware. My server met all of the requirements, but they explained to me that the 2 GB of memory that is required is a minimum, and that in many cases more memory is actually required. From what I have been able to gather, if the server pages data to virtual memory during the replica creation or synchronization, it will cause the replica to become inconsistant.
Unfortunately, I am operating DPM on an older server, and the server’s system board can not accomodate more than 2 GB of RAM. Since I can’t add any more memory to the server, and replacing the server isn’t an option right now, I tried disabling the server’s virtual memory.
Only time will tell if this was a good idea or a bad idea, but as of right now all of my replicas are consistant. I’ll keep you updated on how this idea ends up working out.
