WARNING: This plugin is for advanced users. If used incorrectly it could wipe out all your content!

Keeping databases in sync between development, staging and live servers can be a pain. This plugin lets you link together several WordPress installations by sharing a secret token. Once linked, administrators can pull or push the entire database between servers with just a click.

Currently syncs database only, not uploaded files.

Backups

The plugin will attempt to make local backups of the database before overwriting. These are stored as gzipped SQL files in wp-content/plugins/database-sync/backups/dbYYYYMMDD.HHMMSS.sql.gz The backups directory should be made writable, and you should keep an eye on it if you sync often as it will grow in size.

Usage

See Installation instructions.
