Limiting I/O usage
 

Hi,

Is there any way I can limit the I/O usage of a process or all the processes in a system. I have a server which regularly tars the log files and does a backup. But during this tar operation I see heavy iowait in the top command, which causes my other process to timeout.

Is there any way I can reduce the iowait when tar is running so that the other processes are not effected.

Thank you.
