Recommended Posts

The compare took 8 minutes, but creating snapshot took almost 7 hours; using multiserver 7.7.562; with client 7.7.114.

 

This problem also occurs using OEM Professional 7.6.123; with client 7.6.107.

 

This has been an ongoing problem since a Windows Update more than 5 or 6 months ago; on Winodws 7 x86 & x64 clients.

That is not a solution to the problem just a reason to use different backup software.

 

Looking at Process Explorer the pcpds.exe Process moves through files (Handles) very slowly while using high CPU, a fix to pcpds.exe client-side would be a better resolution.

Well, pcpds just calls the standard Windows' APIs, just like any other backup software. So i's Microsoft that needs to speed up their registry access.
