You can use Performance Monitor, with some counters you can see backup and any program using CPU. Also run Profiler to find if there is some queries taking CPU. Luis Martin Moderator SQL-Server-Performance.com
Ideally the backup of the database shoud be carried out during low activity period as it dews consume server resources. There is no saperate process for the same.

What about memory settings of memory on SQL Server? ANy other applications are sharing the server resources? During the backup process run SP_WHO or SP_WHO2 and see physical disk activity for that process.

Seriously consider identifying slow running queries using Profiler and trying to tune them as much as possible. This is a big job, but it can significantly help reduce the current load on your server. ----------------------------- Brad M. McGehee, MVP Webmaster SQL-Server-Performance.Com
