Could you elaborate that? purge and purge-full are just two approaches for the 
same goal. If you know that you do fulls monthly it is more humanly 
understandable to say keep 3 fulls and use the purge-full command, but you 
could as well say keep 3 month using the purge command.

You mean of fulls vs. incrementals? Think about how often you change your data 
and how important it is to be able to restore yesterdays state, last weeks 
state and so on and consider that a corrupt incremental corrupts all following 
incrementals upt to the next full.

You should of course always verify after backing up if possible.
