In this case, when you carry out the first incremental backup, it is an incremental backup for both T1 and T2. Most likely or not, the WALs are shared and overlapping. > Selection of WAL files eligible for incremental backup is broken > ---------------------------------------------------------------- > > Key: HBASE-15094 > URL: https://issues.apache.org/jira/browse/HBASE-15094 > Project: HBase > Issue Type: Sub-task > Reporter: Vladimir Rodionov > Assignee: Vladimir Rodionov > Fix For: 2.0.0 > > > We should add to a selection WAL files which have been copied over by different backup sessions and which are newer than the most recent files processed for a given table. Currently, we look for WAL files only in a files system (WALs and OldWALs directories) > Scenario > Full Backup T1 > Full Backup T2 > Created WAL1 > Incremental Backup T1 (WAL1 becomes eligible for deletion) > some time later > Incremental Backup T2 (WAL1 can be deleted by this time and won't get it into WAL file list for T2) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
