This statement isn't correct. There are, in fact, tools for doing incremental backup and restore with PG and they work quite well, as I mentioned. Currently they operate at a file-level, which means 1G chunks instead of block-level, but there is work being done to change that too. There isn't anything in "PG technology" that makes this impossible or, really, even that difficult, it's more that there hasn't been effort put into it simply because the file-level incremental solution works quite well in most cases. Thanks! Stephen
