1. When enabling collocation for a group of servers, does a full
backup
of the servers occur to group the data on as few volumes as possible
followed by incremental backups? Or do incremental backups still occur
as normal and are simply grouped on pre defined volumes?
William -

There is no change in Incremental backup behavior because of
collocation:
if an object is in the target storage pool already, it will not be
backed
up again, regardless of how the storage pool is arranged.

2. Is there a way to collocate data already backed up onto fewer
volumes?
All subsequent data movement within the storage pool (reclamation,
Move Data, Move Nodedata) will observe the collocation rule.
The Admin Guide has good info on this.
