What It Is

DeltaBackups is a backup and migration plugin service for WordPress. It is positioned as a way to protect website files and databases with encrypted cloud storage, while enabling fast recovery through versioned backups. Its target users are clearly defined: WordPress site owners, maintainers, and agencies managing multiple client sites.

Core Features and Enterprise Capabilities

The product’s headline feature is Delta Versioning, which stores only the changes made since the previous backup. In theory, this can reduce backup time and storage usage. Backup data is encrypted before upload, covering both files and databases, and is stored in serverless cloud storage. For recovery, users can choose a specific version or restore the entire site; the migration tool can move a site to a new host or a new domain. All plans support unlimited WordPress sites, which is an attractive design for users maintaining multiple sites.

From an enterprise software perspective, DeltaBackups discloses relatively limited information. The available materials do not show team member management, granular permissions, audit logs, SSO, APIs, webhooks, or third-party SaaS integrations; only WordPress integration is clearly stated. On security, it only mentions encryption and PHP version requirements: encryption requires PHP 7.2.0+, while decryption supports PHP 5.6.0+. It does not disclose the encryption algorithm, data regions, backup retention policy, SLA, or compliance certifications.

Pricing

Pricing is subscription-based: €10/month includes 10GB of cloud storage and 300GB of restore network traffic; €25/month includes 25GB and 750GB; €100/month includes 100GB and 3000GB. Network traffic is mainly calculated when data is retrieved during restoration. The official site also mentions that a free version can be downloaded from the WordPress plugin directory, but it does not specify the free version’s storage limits, feature set, or trial restrictions.

Pros, Cons, and Who It’s For

The strengths are its focused feature set, simple onboarding path, support for incremental backups, encryption, restoration, and migration, plus unlimited site support. The drawbacks are limited transparency, especially around backup policies, service availability, enterprise collaboration, and compliance capabilities. Its terms also state that the service is provided “as is” and “as available,” with no guarantee that it will be uninterrupted or error-free. It is better suited to small and medium-sized WordPress site owners, freelance developers, and agencies, and less suitable for enterprises with strict requirements around auditing, permissions, compliance, and SLAs.

Access from China

The main materials do not provide information on access from China, payment methods, or localized support, so real-world usability needs to be tested. If access or payment is restricted, alternatives to compare include UpdraftPlus, BlogVault, Jetpack VaultPress Backup, ManageWP, and Duplicator.
