<p>I currently have an MS Access application that connects to a PostgreSQL database via ODBC. This successfully runs on a LAN with 20 users (each running their own version of Access). Now I am thinking through some disaster recovery scenarios, and it seems that a quick and easy method of protecting the data is to use <a href="http://www.postgresql.org/docs/8.3/static/warm-standby.html" rel="noreferrer">log shipping</a> to create a warm-standby. </p>

<p>This lead me to think about putting this warm-standby at a remote location, but then I have the question:</p>

<p><strong>Is Access connecting to a remote database via ODBC usable?</strong> 
I.e. the remote database is maybe in the same country with ok ping times and I have a 1mbit SDSL line.</p>

I have been involved in a reasonably big system (100+ PostgreSQL tables, 200+ Access forms, 1000+ Access queries &amp; reports) and it has run excellently for a few years, with ~20 users. Any queries running slow because Access is doing something stupid can generally just be solved by using <a href="http://www.postgresql.org/docs/8.3/interactive/sql-createview.html" rel="noreferrer">views</a>, and any really data-intensive code can easily be moved into PostgreSQL functions and then called from Access.</p>\n\n<p>The only main ODBC-related issue we have is that there is no way to kill a slow running query from Access, so we do often get users just killing Access and then massive queries are just left executing on the server.</p>\n'}, {'answer_id': 113354, 'author': 'Community', 'author_id': -1, 'author_profile': 'https://Stackoverflow.com/users/-1', 'pm_score': -1, 'selected': False, 'text': '<p>PostgreSQL works great as a backend for MS Access, there are a couple of support functions you should use to make things easier.
