backup process highly intense on cpu

Anyone know why the backup process is extremely intensive on cpu usage?

I'm using a dual xeon 3.0GHz HT server with 4GB of memory
and 10k SCSI disks (primary / backup secondary both SCSI)

During backup process the load sky rockets past 10 CPU, sometimes much higher. In the end, it causes the server to run slower dramatically and therefore causing the backup process for all accounts to take much longer.

Server Details:

Dual Xeon 3.0GHz HT
4GB Memory
SCSI Disks (both) 10k
Centos 4.3
Cpanel 10.x RELEASE

Approx 25-30% diskusage (600 accounts estimate, 90% or so are reseller's client accounts
that are virtually tiny)

I had to disable the automated backup because of the high CPU usage and the fact that it crashed my server fairly often. I had set the CPU level in WHM fairly low, too.. but it's just not feasible to run the backup as is because of the CPU usage, and the fact that it slowed my server to a crawl.

This was on a dual P4 2.8ghz with 512mbs of ram.

Compression is naturally going to take a lot of processor time - we had that problem, and then I sprang for 300 Gig backup drives, switched to incremental, and now backups are hardly a blip on the radar - if you can afford the space or cost of the extra drive, I highly recommend it.
