Vladimir Rodionov commented on HBASE-14417:
-------------------------------------------
Delete file ref from hbase:backup after backup completes - do not keep them
there forever.
Now we have two different types of files in backup : HFile (snapshot/full), WAL
(incremental). Bulk load adds third type - HFile (bulk load/incremental)
*Shipping HFiles to backup destination
*New storage layout for incremental backup image, that has bulk loaded files?
*The algorithm for restore incremental backup that has both : WALs and HFiles?
> Incremental backup and bulk loading

> 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).
