> By default, restore operation runs with automatic off and overwrite off. This is not
what user expect (point -in -time data restore).  
> When automatic is off, only last backup image will be restored - the image user requested.
With automatic on - the whole image dependency chain will be restored, starting with the most
recent full backup image, followed by incremental images. This is should be default.
> When overwrite is off - we face issues similar HBASE-15862 ( Backup - delete data - restore
from backup results in missing data). Overwrite is off by default.
> Definitely, we  need to make, at least, both modes to be default ones, at least. The
question do we need these exotic modes at all? What are use case for them?
> Please cast your vote, comments are welcome.
