Replication of a remote MySQL database to local MySQL database I'm the developer of my employers corporate private website, a HTML5/PHP/CSS powered site for company reports etc. The site, hosted on a shared hosting package, connects to a remote read-only MySQL DB server for authentication and report data queries. This remote DB is mainly used by a separate windows exe.

The remote DB goes down frequently which of course causes the private website to bomb out on a MySQL connection error. I've thought about replicating the remote DB to the site's local hosted MySQL DB and using the local DB as the site's primary and only DB connection.

Is there a way of synchronising the remote DB to the site's shared hosting DB in a simple and pain free way? Like every hour it updates or something?

Or is there a function where the site's hosting package MySQL DB functionality can cache the remote DB data and use that as a fallback.

Thanks in advance.

It explain how to Compare-Copy a DB to another DB, my case is the same as yours.

Depending on your access level you can:


Use a external client as middle man (to make de compare-copy)
Script in PHP to check new lines in the original DB and copy them
Use one of the many tools of MySQL to copy 


MySQLDBCompare
MySQLDiff
MySQLDBCopy
