Jerry He commented on HBASE-15862:
----------------------------------

An issue with the 'truncate' is that it preserves the schema of the table.
It is possible the current table schema is different (e.g. with a new column 
family or a column family has been dropped).
The restore (bulk load) can fail due to mismatch column families.  (This can be 
fixed with some kind of 'ignore').
But again the table is not in a PIT state in the past.

> Backup - Delete- Restore does not restore deleted data

> This was discovered during testing. If we delete row after full backup and 
> perform immediately restore, the deleted row still remains deleted.
