Lars Hofhansl commented on HBASE-6055:
--------------------------------------

Let's try to avoid going overboard here.
In principle snapshot and backup/restore are different and independent.

A snapshot generates a consistent snapshot of the data that can subsequently be 
copied conveniently somewhere else - thus creating a backup.

Ideally we would not even prescribe the backup/restore semantics here, but just 
provide missing building blocks.

Just my $0.02.

Another thought here is: In principle an HFile resulting from a major 
compaction could be considered a baseline copy and additional HFiles would be 
incremental changes on top of that baseline. It might be worth considering if 
we can make use of this ability of HBase to overlay changes from many sources 
into a single view of the data (would probably be tricky as regions are flushed 
in sync, etc, just waving hands here).
