Hi

Can any one explain how to snapshots and how it works for my case.

i took a snapshot for the data in my volume for the first time and later i made many changes to the data ,if i accidently delete data .How can i restore the first copied data and the changes made to that data(deltas) for that point using snapshot

i did some thing like
hadoop fs -ls /user/xxxxx/.snapshot/2013-03-25.00-00-00/example.txt

hadoop fs -copyToLocal 2013-03-25.00-00-00/nohup.out /test_dir/

hadoop fs -copyFromLocal /test_dir/example.txt /user/xxxxx/

but how to apply all the deltas to that example.txt to become that point of data

thanks in advance
