doesn't a wal archive give you pretty much the same thing?
No, because WAL quickly enough may become larger than the database.
In the WAL can be any number of records that change only one page of
memory.
In addition recover from the WAL too long, because it should be "play" by
Postgres.
In my case pg_arman + ptrack it's almost as simple copy files.
Thanks.
