Users appreciate BlogVault for its reliable backup and migration capabilities, exceptional customer support, and extensive security features, including malware scanning and two-factor authentication. The plugin is praised for its ease of use, rapid restoration processes, and detailed reporting. Users highlight that it provides peace of mind by protecting against data loss and hacking. However, some drawbacks include the plugin's hidden presence in the WordPress dashboard, which complicates its removal, concerns over unauthorized access by BlogVault employees, slow performance due to additional security features, and misleading advertising about a "free" version that is only a 7-day trial.
