Adjust disk scheduling priority for a process?

Hi all!

Some dumb administrator run the weekly backup "by hand" on our AIX 5.3 server, which we use to deploy Websphere applications, during work hours. Using the server while the backup is taking place is almost imposible. Both the disks are working at 100% and it's almost unusable. Asking the administrator to move the backup schedule is so politicaly difficult that I'd rather modify the running backup process myself!
As I posess root access to this server, I have already tried to renice the process but, although the server is more responsive, it's still using the disks massively and any disk-related operation takes ages.
My question is in the subject: Is there a way to reschedule the priority of a process's access to the hard drive? Say, a command that tells the OS something like "process 1028246 can't use more than 50% of the disk" ?

Thanks in advanced for any help!
Yours,

Shandrio

BBACKUPD-CONFIG(8)						    Box Backup							BBACKUPD-CONFIG(8)

NAME

       bbackupd-config - Box Backup client daemon configuration file generator

SYNOPSIS

       bbackupd-config config-dir backup-mode account-num server-hostname working-dir backup-dir [backup-dir ...]

DESCRIPTION

       The bbackupd-config script creates configuration files and client certificates. It takes at least six parameters:

       config-dir
	   Configuration directory. Usually /etc/box.

       backup-mode
	   Either lazy or snapshot.

       account-num
	   The client account number. This is set by the bbstored administrator.

       server-hostname
	   The hostname or IP address of the bbstored server.

       working-dir
	   A directory to keep temporary state files. This is usually something like /var/bbackupd. This can be changed in bbackupd.conf later on
	   if required.

       backup-dir
	   A space-separated list of directories to be backed up. Note that this does not traverse mount points.

FILES

       /etc/box/bbackupd.conf

       /etc/box/bbackupd/NotifySysAdmin.sh
