I have Time Machine configured to backup to two different disk drives. 
It is my understanding that this will alternate the hourly backups to 
the two drives. If I open Time Machine preferences it does indeed show 
that the most recent backups to the two drives are an hour apart. 
However when I enter Time Machine the tabs on the righthand edge of the 
screen have two for each hourly backup, one for each of the backup 
drives. Are two concurrent backups actually happening or is this a 
mistaken display on the part of Time Machine?
