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?
