> 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
> 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.
