Note:

There is cost when BackupObserver is registered - it would poll backup table (at the end of bulk load per region) for whether the underlying table has gone thru full backup.

> Over in HBASE-14417, two new classes are added.
> org.apache.hadoop.hbase.backup.BackupHFileCleaner should be registered through hbase.master.hfilecleaner.plugins . It is responsible for keeping bulk loaded hfiles so that incremental backup can pick them up.
> org.apache.hadoop.hbase.backup.BackupObserver should be registered through hbase.coprocessor.region.classes
> It is notified when bulk load completes and writes records into hbase:backup table.
