What is a HBase backup strategy?
For RDBMS systems, people normally backup their data from time to time. What
is the backup strategy (and using what tool) for HBase?
Thanks,

I'm pretty sure it could potentially create an inconsistent copy of

distcp into a different hadoop cluster nightly, maybe a valid choice as

One option is to use org.apache.hadoop.hbase.mapreduce.Export
Later you can Import the data back.
