Anyone using DPM 2012 R2 for backup on Windows 8.1 64-bit laptops? - any issues like freezes/crashes?

Question

We've been using this for a a few months now, still testing. Feedback initially good, but now noticed users reporting back their laptops are freezing, typically when using Outlook. It's been a hard one to figure out, but the only common factor we can see
to prevent this happening again is to disable or remove the DPM client.
We are looking into all possibilities like anti-virus exclusions etc, but just wondering if anyone has seen anything like this before, got any ideas? Thanks!

Hi,
Try this - On the client - Increase the WaitInMSPerRequestForClientRead to 100 to take the load off the client and  DPM when synchronizations are in progress.

On some client computers, you may notice the computer running slow when a backup is in progress. You can improve the computer’s responsiveness by setting the following registry key DWORD.
Key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Data Protection Manager\Agent\ClientProtection
Value
WaitInMSPerRequestForClientRead
Data
50
Type
DWORD
NOTE: Optimizing WaitInMSPerRequestForClientRead settings 
The default value for WaitInMSPerRequestForClientRead DWORD is 50 (32H). This means the dpm agent will wait 50ms per read cycle to locate changed data. You can increase the value to 75 or 100 to reduce IO on the disk to improve machine responsiveness at
the cost of longer backup times. If you want to increase backup speed at the expense of responsiveness, reduce the value to 40 or 30.
