Jerry He commented on HBASE-15862:
----------------------------------
Again, the -overwrite option is tricky, and should be used cautiously and in
certain use cases that the user are aware.
IIRC You will see exactly the same problem if you:
1. Export table1
2. Delete some rows
3. Import back the exported data into the same table.
4. The deletes are still effective.
I think the semantics and policy of the each backup/restore ops need to be
thought out and clearly defined.
> 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.
