Ted Yu commented on HBASE-14417:
--------------------------------
Currently there is one BulkLoadHandler inside each region server which writes
BulkLoadDescriptor periodically to hbase:backup table.
Ideally only BulkLoadDescriptor's for tables which have gone through full
backup should be written.
Looking for a way to pass Set of such tables to region servers so that each
server doesn't have to poll hbase:backup table periodically.

> 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).
