             Summary: HBase Backup/Restore Phase 2: Keep WAL files in a centralized place to avoid duplication
                 Key: HBASE-15372
                 URL: https://issues.apache.org/jira/browse/HBASE-15372
             Project: HBase
          Issue Type: Improvement
            Reporter: Vladimir Rodionov
            Assignee: Vladimir Rodionov


Currently, we keep WAL file per table in backup site, this creates significant data duplication in case of many tables in a backup set. We have to keep all WAL files in a single place and keep track of WAL files involved per table/backup id as links (references)
