Devaraj Das commented on HBASE-14135:
-------------------------------------
bq. Originally it was Service, then - Task, now is Job. What do you suggest,
stack?
How about _process_? Seems generic enough to capture MR Job among other
possibilities.. Stack?

> 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.
