Vladimir Rodionov updated HBASE-16037:
--------------------------------------
Description:
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.
