Yes.  QOS (see mmchqos) is now the way (4.2.x) to control maintenance 
commands like snapshots, backup, restripe.

I found this link and it didn't give me much hope for doing snapshots & 
backup in a home(busy) filesystem:

I realize this is dated and I wondered if qos etc have made is a tolerable 
thing to do now.  Gpfs I think was barely above v3.5 in mid 2013.
