Not a full explanation as to why the other perfmon counters are low but the pages/sec counter is high. &nbsp;However, it does confirm my theory so it's good enough for me!

<div>
<div class="content wysiwyg-content">
I am running a few perfmon counters against a Backup Exec server.<br />
<br />
Win2k3 Enterprise (Fully patched)<br />
12GB Physical memory using the /PAE switch<br />
Symantec Backup Exec 2010 R2 (SP1) using SQL Server<br />
<br />
Here are the perfmon stats for an entire day:<br />
<br />
CPU usage does utilization does not exceed 20%<br />
Physical Disk transfers/sec does not exceed 15<br />
Physical Memory Utilization does not exceed 10%<br />
Page File Usage is at less than 1%<br />
Pages/sec spikes constantly from 516 to 5,160 (While Backup Exec is running a backup)<br />
<br />
<br />
My question is this. &nbsp;Does Backup Exec read a high number of memory mapped files while executing backups? &nbsp;Would this cause the Pages/sec counter to spike while not really causing any kind of performance degradation? &nbsp;<br />
<br />
Is this expected behavior?<br />
<br />
Thanks much!<br />

Backup Exec and high pages/sec.  Expected Behavior?

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
