Users highly praise the WPvivid plugin for its ease of use, reliability, and comprehensive features available even in the free version. They appreciate its capabilities for backing up, restoring, and migrating WordPress sites, which brings them peace of mind and convenience. Additionally, the plugin's ability to integrate with cloud services like Amazon S3 and Nextcloud, and perform scheduled and incremental backups, is well-regarded. Users particularly commend the responsive and helpful support, especially from a team member named Nicholas. However, some users faced issues with hosting limitations, character set mismatches during restorations, and occasional timeouts during exports to Nextcloud. There's also criticism regarding the lack of SSH key support for SFTP and complex settings. Despite these drawbacks, the plugin's strengths make it a favorite backup and migration solution for many.
