[support] WAS Why .. now 3 ways to save the db which is best

[Andy Heath]

Following on from my post one twig up in this thread ..

So now I have three ways to save the database:

1. syncing from another machine with %dump=wherever... in the alias
2. drush sql-dump --result-file=wherever...
3. drush sql-sync @mysite @mysite

They all produce different sql - which is best?

 From a processing perspective admittedly 3. is terrible because I 
presume it exports the db then re-imports it.

I seek a reliable practice to adopt then if I always do it the same way 
I can happily shove the current db in a git repo (hey its only a small 
database).
