generally single program could not make that - FreeBSD schedules tasks
well. in certain cases it may be like that.
For example - programs that runs for long time constantly and uses CPU
gets automatically "downgraded" so your newly run backup task can make
them really out of CPU power.
will help you - get your backup program priority down.
Actually i don't know if "downgrading" (called autorenice) can be disabled
for certain processes. If would make sense for - say - database servers.
