If data is less in your cluster (say less than few GBs) then answer is yes. But it is an expensive
route. For large data sets, traditional means is not feasible and it is expensive. 
If you want optimal cost based solution, you could setup another local/remote cluster and
try discp or simply copy hdfs files to JBODs. Disk is cheap :).

Subject: backup of hdfs data
 

What do folks do to backup hdfs data? 
Has anyone experience in trying to use enterprise solutions such as netbackup with datadomain
D-2-D appliance for doing backups of data in hdfs? If so, what is the average dedup ratio?
(I understand mileage can vary based on the type of data)

Thanks,
Uday
