-----------------------------------------

             Summary: Save table descriptors and region infos during incremental backup 
                 Key: HBASE-14446
                 URL: https://issues.apache.org/jira/browse/HBASE-14446
             Project: HBase
          Issue Type: Sub-task
            Reporter: Vladimir Rodionov
            Assignee: Vladimir Rodionov
             Fix For: 2.0.0


The current implementation of incremental backup just moves WAL files into backup directory.The
restore procedure of incremental backup relies on full restore (from snapshot) as source of
all table meta. 

Two problems: 

# Table configuration/properties may be changed after full backup and we will loose this info
during restore
# We can not convert WAL files into HFiles w/o having table description and layout. Need for
merge tool
