It looks like it was first introduced in: 1.0.0.Beta2 <http://www.elasticsearch.org/downloads/1-0-0-beta2/>
December 2, 2013 - Snapshot/Restore API – Phase 1 #3826 <http://github.com/elasticsearch/elasticsearch/issues/issue/3826> This preceded 0.90.9, so I would suspect that it's in your 0.90.10 version as well.
