I really hope they weren't backing 25TB of data with RAID controllers, this is well out of RAID league and well into the territory of distributed file system techniques. I ditched RAID years ago for ZFS for only an 18TB file server at home. Start talking about thousands of servers and RAID is pretty useless. That said, IANAL but I think the interesting thing here is that just making copies of the hard drives is likely not enough from a evidence standpoint. With such a data set there are likely layers of data abstraction software that would be need to be replicated to make any sense of it.
