> the jira is part of
> [HBASE-7912|https://issues.apache.org/jira/browse/HBASE-7912], and depend on
> full backup [HBASE-10900| https://issues.apache.org/jira/browse/HBASE-10900 ].
> When client issues an incremental backup request, BackupManager will check
> the request and then kicks of a global procedure via HBaseAdmin for all the
> active regionServer to roll log. Each Region server will record their log
> number into zookeeper. Then we determine which log need to be included in
> this incremental backup, and use DistCp to copy them to target location
> Restore is to replay the backuped WAL logs on target HBase instance. The
> replay will occur after full backup.
> As incremental backup image depends on prior full backup image and
> incremental images if exists. Manifest file will be used to store the
> dependency lineage during backup, and used during restore time for PIT
> restore.
