I only need the last 24, overwriting each day. In my case 8 are enough (8am to 24pm, one every 2 hours). The important thing is to be able to open each very simply (read only) without restore anything. Just tell my application (written be me), to point the basckup database instead of latest one. > Have you tried pg_dump? probably this is ok. pg_dump create a backup file, not a true clone db. I want a exact copy (data and users and everithing) with a different name (05-mydatabase 06-mydatabase ...)
