I'm currently using hbase 0.18.1 and looking to move to trunk until 0.19 is available and stable. I have a reasonably sized dataset built up (255 regions in one table) that I'd prefer not to lose, mostly because of the time it takes to reload it from the source data. My primary concerns are issue that may lead to table corruption or other data loss. To mitigate things I'm looking for backup strategies. My cluster is currently pretty small and I'm far more limited by memory than disk space, so I have a lot storage to use for backup purposes. As a simplistic approach, I was considering just stopping hbase and making a copy of its directory on DFS. Does anyone have any experience backing up HBase to offer alternatives/suggestions?
