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] 
and incremental backup [HBASE-11085| 
https://issues.apache.org/jira/browse/HBASE-11085]. for the detail layout and 
frame work, please reference to  [HBASE-10900|

A backup operation may need to move handreds/thousands GB of data, and takes 
hours. Sometimes, the operation may take longer than the original maintenance 
time window planned by the administration. So it is necessary to have the 
functionality to cancel the operation and reset all the history/manifest info 
whenever necessary. so that we can have a clean backup in the next time window
