Monitoring Windows System Performance During Backup
This article refers to Barracuda Backup firmware version 5.0 and higher, and Microsoft Windows 7, Windows 8, Windows Server
2003, Windows Server 2003 R2, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Vista, and
Windows XP, except where noted.
During backup, your organization may encounter performance or resource contention. To reduce this possibility, first evaluate the systems in your
environment for hardware-specific performance limitations. Once this is determined, configure data sources for backup, and then monitor system
performance using a system performance monitoring tool.
Monitor Windows System Components
Evaluate Windows system components using a tool such as Windows Performance Monitor to evaluate performance in real time during backup or
by reviewing historical data. You can view the results in graph, histogram, or report form. This utility organizes the results by object, counter, and
instance which you can customize as data collector sets:
Performance counters
Event trace data
System configuration information (registry key values)
An object is a system resource category, and counters are the properties of that object. For example, and are% Processor Time Interrupts/sec
counters for the object.Processor
Once the USN change Journal is recreated, Barracuda Backup goes through the entire file system which may result in a longer
backup.
This utility is available for Windows 7, Windows Server 2008 R2, Windows Server 2012, and Windows Vista.
