Richy_Boy Posted March 31, 2010 Report Share Posted March 31, 2010 Hi all, Ive been looking at how to speed snapshots up on our backup server quickly today since introducing a seperate local HDD to hold catalogue files (away from the Servers C: drive). What I have noticed is that machines seem to be spending some time snapshot'ing the client. However, when using Performance Monitor to see what is being hammered during this, I was suprised to see 'nothing' happening. I was expecting to see CPU, network or disk being hammered to explain why it's taking so long. Please see below: Two of these clients are currently in a snapshot phase. Is this right? A Snapshot is taking place, but no CPU, network or disk is being used? Rich Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted March 31, 2010 Report Share Posted March 31, 2010 I believe the snapshot is being built on the client and then transferred to the Retrospect server. Quote Link to comment Share on other sites More sharing options...
Richy_Boy Posted March 31, 2010 Author Report Share Posted March 31, 2010 ahh, that'll explain why our laptops freeze at the end of backups then! I always thought it was done server-side. Thanks! Rich Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted March 31, 2010 Report Share Posted March 31, 2010 The client gathers the state of all files and makes a copy of the complete registry. I always thought Windows was a multi-tasking OS until I started using Retrospect.  ;-) Quote Link to comment Share on other sites More sharing options...
poorman Posted March 31, 2010 Report Share Posted March 31, 2010 Multi-tasking, yes. That's probably actually part of the cause of the "freezes". It's easy for several processes running in a system to get into a fight over the position of the heads in a system with a single hard disk. Head positioning is extremely slow compared to just about anything else in a modern PC, and the tasks all end up waiting for it. Laptops usually only have one disk, and those disks positions the heads slowly to reduce power consumption. -- Pete Quote Link to comment Share on other sites More sharing options...

However, our Windows laptop users has always complained about poor responsiveness (to put it mildly) while our Mac laptop users has NEVER complained. Even if the Macs are much older and slower.

Richy_Boy Posted April 1, 2010 Author Report Share Posted April 1, 2010 I would agree, our staff can just be sitting in Outlook reading a few emails and then the machine will become completely unresponsive for 10-20 seconds while (I now assume) the snapshot is taking place client-side. I'm assuming the 'priority slider' in the client app is ignored when building a snapshot? Rich Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted April 1, 2010 Report Share Posted April 1, 2010 (edited) I'm assuming the 'priority slider' in the client app is ignored when building a snapshot? The slider setting has been ignored in all client versions for years.
