You should definitely worry about the number of files when it comes to backup & management. It will also make a big difference in space overhead.
A ZFS filesystem with 2^35 files will have a minimum of 2^44 bytes of overhead just for the file nodes, which is about 16 TB. If it takes about 20 ms for the overhead to backup a file (2 seeks), then 2^35 files will take 21 years to back up. ;-) I'm guessing you didn't really mean 2^35, though. (If you did, you're likely to need a system along the lines of DARPA's HPCS program....)
