System requirements and site health

Backvera works on virtually any standard WordPress hosting. This page lists what your site needs, and how to check a connected site’s health on its Connection card.

Requirements

  • WordPress 5.0 or newer.
  • PHP 7.4 or newer.
  • A MySQL or MariaDB database (standard for WordPress).
  • The WordPress REST API enabled and reachable – Backvera uses it to start and coordinate backups. Some security plugins or hosts disable or restrict it; if yours does, allow it (at least Backvera’s routes). Plain and pretty permalinks both work.
  • Outbound internet access, so the Backvera plugin can reach Backvera.
  • Reachable from the public internet, so Backvera can reach your site for the connection test and for backups.

The Connection card

Open the site and go to Settings > General. The Connection card shows the plugin heartbeat (last ping), the plugin version, PHP and MySQL versions, and the memory limit – so you can confirm at a glance that everything meets the requirements above. Use Test connection to check connectivity on demand.

Low-memory hosts

If your host caps PHP memory very low, Backvera flags it on the Connection card – very tight limits can slow or interrupt backups. Raising the PHP memory limit, or asking your host to, resolves it.

Common blockers

If a connection test or backup cannot reach your site, the cause is usually something sitting in front of WordPress:

  • A security plugin or firewall blocking the REST API or wp-admin – allowlist Backvera, see how Backvera appears in your logs.
  • HTTP basic auth or an IP allowlist in front of the site.
  • Maintenance or “coming soon” mode that hides the site.
  • The site not being reachable from the public internet – for example, a staging server behind a VPN.
