Ted Yu updated HBASE-14417:
---------------------------
Attachment: 14417.v25.txt
Patch v25 deletes the copied bulk loaded files upon deletion of backup.
There is some enhancement in LoadIncrementalHFiles which is only in master
branch.
I would wait after the merge before publishing review request.

> Currently, incremental backup is based on WAL files. Bulk data loading
> bypasses WALs for obvious reasons, breaking incremental backups. The only way
> to continue backups after bulk loading is to create new full backup of a
> table. This may not be feasible for customers who do bulk loading regularly
> (say, every day).
