Remote Storage: Backblaze (Pro)

Jan 23, 2026 | Knowledge Base

This guide explains how to configure WPvivid Backup & Migration Pro to store backups on Backblaze B2 Cloud Storage, including connection setup, folder organization, and retention policies.

What Is Backblaze Integration?

Backblaze B2 integration allows you to organize backups using a parent folder and site-specific subfolder within an existing B2 bucket. You can define custom folders for each website within the same Backblaze account to keep backups well organized.

Path Example:

  • 1. .../wpvividbackuppro/site_a_com/
  • 2. .../wpvividbackuppro/site_b_com/

This folder structure helps keep backups organized when managing multiple websites within the same Backblaze bucket.
