-------------------------------------------

If it would be too difficult (which is what my gut-reaction was), a
tool/utility to summarize these (expected) transient data (files in HDFS and
hbase:backup records) would be really nice to have. If/when we would have to
debug some kind of issue WRT backups or just HDFS use by hbase, such a tool
could give us a definitive yes/no as to whether these transient files are to
blame or not.

We do have repair tool. It takes care of most failure scenarios (not all of
them probably) and does housekeeping appropriately.

> User can merge incremental backup images into single incremental backup image.
> # Merge supports only incremental images
> # Merge supports only images for the same backup destinations
> Command:
> {code}
> hbase backup merge image1,image2,..imageK
> {code}
> Example:
> {code}
> hbase backup merge backup_143126764557,backup_143126764456
> {code}
> When operation is complete, only the most recent backup image will be kept
> (in above example - backup_143126764557) as a merged backup image, all other
> images will be deleted from both: file system and backup system tables,
> corresponding backup manifest for the merged backup image will be updated to
> remove dependencies from deleted images. Merged backup image will contains
> all the data from original image and from deleted images.
