HBASE-14414 is a JIRA with a list of random seeming issues w/ non-descript summaries: "Add nonce support to TableBackupProcedure, BackupID must include backup set name, ...". The last comment in that issue is from July. It asks: "How do I figure what of backup/restore feature is going to be in hbase-2.0.0? Thanks Vladimir Rodionov <https://issues.apache.org/jira/secure/ViewProfile.jspa?name=vrodionov>." to which there is no answer. Doc update is TODO.
Where is the summary of the capability in hbase-2? What testing and at what scale has testing been done? Is this 'stable or experimental'? If I can't get basic info on this feature though I ask repeatedly, what hope does the poor old operator have?
