you'll probably find some answers in the comments of a similar Slashdot post: http://it.slashdot.org/article.pl?sid=05/03/21/1635210 Check out http://advocacy.postgresql.org Two other examples are Whitepages.com (375GB) and the .org registry as well. On Wed, March 23, 2005 17:07, David B said:

If you are running version 8, you may want to look into the WAL archiving: http://www.postgresql.org/docs/8.0/interactive/backup-online.html That would form the basis of your incremental backup strategy. I haven't had the joy of using them myself however, and do not know of any tools to make it
