Hi all,
I have a 3G AM2 quad core CPU... x86_64 centos 5.3
When I am doing backing up to my external USB drive my system becomes sluggish. Clicking on a thunderbird compose takes some time to pop up the window. Typeing doesnt keep up etc...
Is there something I can change so this backup doesnt slow my system down so much? I dont see HOW it can be taking so much CPU. top at times shows 0 idle or 11% idle from a USB backup.
Thanks for any suggestions.
Define 'backing up to my external USB drive':
Are you:
1) Using dump, tar, cpio, or cp? 2) Are you compressing the backup? With gzip or bzip? 3) Are you using zip?
If you are using bzip, bzip is a cpu hog.
How much memory do you have?
What kind of disks do you have? IDE? SATA? If SATA, is the controller in AHCI mode or IDE mode?
