tar to backup my server once every day. Even though CPU usage (of the
tar command and the system overall) doesn't go over 10%, my system load is like
3.98 3.71 3.82 when the script is running. (on a 2 core 4 thread system)
Why does tar show so little CPU in practice, while producing such a high system load in the meanwhile. And, most importantly, should I be worried?
I don't use compression, just a pure tarball. I compress at the start of each new month.
