Backup Exec and high pages/sec.  Expected Behavior?

I am running a few perfmon counters against a Backup Exec server.

Win2k3 Enterprise (Fully patched)
12GB Physical memory using the /PAE switch
Symantec Backup Exec 2010 R2 (SP1) using SQL Server

Here are the perfmon stats for an entire day:

CPU usage does utilization does not exceed 20%
Physical Disk transfers/sec does not exceed 15
Physical Memory Utilization does not exceed 10%
Page File Usage is at less than 1%
Pages/sec spikes constantly from 516 to 5,160 (While Backup Exec is running a backup)


My question is this.  Does Backup Exec read a high number of memory mapped files while executing backups?  Would this cause the Pages/sec counter to spike while not really causing any kind of performance degradation?  

Is this expected behavior?

Thanks much!

hi, there

yes it would be expected high Spikes.
Backup Job are jobs that creates high intensive I/O this is why the spec on a Backup Server should never be the smallest server in your organization.

It is dependent on the RAID set you have configured if jobs goes to disk.
that's why i would never use a RAID 1 for backup to disk as it is slow on writing.

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