We're doing a version of that at Salesforce (we have our own M/R jobs, but the principle is
the same).
Soon we'll run the backup M/R job over a snapshot for performance reasons, but even then the
principle is the same.

Specifically we're keeping 48h worth of life data in HBase itself (TTL=48h, MIN_VERSIONS=1,
KEEP_DELETED_CELLS=true), and run the jobs as of 2h in the past (rounded to an exact hour
boundary), every night.

I think it's time I write an updated blog post. We plan to eventually open source the tools
we've written.

Subject: Consistent Backup strategy
 

Hey guys,

we are searching for a consistent backup strategy with the export tool. Is this article still
up-to-date and I can use it?

Thanks for answers.

cheers,
