Description
VeravalOnline Failover Post Sync with DNS and IP keeps a primary WordPress site and a standby copy in sync. Use it when the same public site runs on Server A and a failover Server B. Publishing on A used to leave B stale, which hurts SEO after DNS failover.
Install the plugin on both WordPress copies. The primary pushes:
- Post title, slug, content, excerpt, status, and exact publish/modified dates
- Featured images and attached media, written to the same uploads path
- Categories, tags, and custom taxonomies
- SEO and custom field metadata (Yoast, Rank Math, ACF, and others)
- Deletes or trash, if enabled
Visitor-facing URLs stay on the public domain. The plugin never rewrites content to the failover IP or internal hostname.
DNS mode: Destination URL is a hostname that already points at Server B (internal DNS, hosts file, or a dedicated failover name).
IP mode: Destination URL is the public HTTPS URL. Destination IP is Server B. Requests keep the real Host/SNI so the SSL certificate still validates.
Installation
- Copy the
veravalonline-failover-post-syncfolder intowp-content/plugins/on Server A and Server B. - Activate VeravalOnline Failover Post Sync with DNS and IP on both sites.
- On both sites, open Failover Post Sync Settings and paste the same Shared API key.
- Server A: role = Primary. Set Destination URL to Server B’s WordPress home URL.
- Server B: role = Failover.
- On Server A click Test connection, then Sync all posts once to seed B.
FAQ
-
Will this change permalinks or image URLs?
-
No. Slugs and upload relative paths are copied as-is. Public URLs stay on the visitor domain.
-
Do post IDs stay the same?
-
Not necessarily. Matching uses a hidden sync GUID, then the same slug. Gutenberg image IDs and attachment meta are remapped automatically.
-
What if we already created some posts by hand on Server B?
-
A full sync updates the failover post that has the same slug, so you do not get duplicates.
