Assuming the disk footprint is small... Would recommend a new SSD-based ZFS box (Samsung 840 Pros have been great even for pretty write-intesive load), with raidz3 for protection and zfs send (and/or rsync from hourly/N-minute snapshot for data protection which should eliminate copying FS metadata corruption, as not sure if zfs send will). Happy to provide and/or host such a box or two if helpful.
