Focus on solving the issue (if any) not on the symptoms or side
effects. There is nothing intrinsically bad/good with how backups are
distributed provided they fit the window you desire and are not
causing load issues.

As others have said, if load average is an *issue*, than the solution
is to reduce the Max backups number. The distribution will then follow
to meet the restriction. However, just because nagios complains, still
doesn't mean it's an issue provided that the high load average isn't
clobbering other critical processes...
