Ted Yu commented on HBASE-14417:
--------------------------------
Discussed with Devaraj.
Quick solution is to detect the presence of bulk loaded hfiles between full
backup and incremental backup. If bulk load is detected, convert incremental
backup to full backup.
Better solution, related to HBASE-14141, is to list bulk loaded hfiles during
incremental backup and put them in their own backup image.

> Project: HBase
> Issue Type: New Feature
> Affects Versions: 2.0.0
> Reporter: Vladimir Rodionov
> Assignee: Vladimir Rodionov
> Priority: Critical
> Labels: backup
> Fix For: 2.0.0
>
>
> 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).
