One more question: since HDFS redundantly stores data blocks in
triplicate, does it make sense to still use traditional backup methods
on data stored in HDFS? If one puts data into HDFS, can one reasonably
rely on the built-in fault-tolerance of the triplicate copies of that
data, or should one still be putting data to tape?
