Why isn't a fourth option being explored: local storage with async replication? Seems like it'd be fairly simple and fast, and no worse than non-clustered NFS regarding data integrity.
I'm just talking from ignorance, so am I missing something?

The simplest storage, is a bunch of dumb servers (well beefy dumb servers) with some application aware scripts to move/copy the dataset.
A place I worked at had a wrapper around rsync that would split up the directory and spawn multiple rsyncs to do a parallel copy.
The Directory structure was effectively copy on write, so backup to the nearline was <15 minutes
