6 Best European Backblaze B2 Alternatives in 2026

BorgBase is a Maltese-registered backup hosting service built specifically for Borg and Restic, the two most widely used deduplicated, encrypted backup tools for Linux and macOS. Backups are encrypted client-side before any data leaves your machine, and append-only mode prevents any process (including ransomware) from modifying or deleting existing archives.

Each repository gets continuous monitoring: if a backup hasn't run within the configured window, BorgBase triggers alerts via email, Pushover, or webhook. A clean REST API automates repository provisioning for infrastructure-as-code workflows. Native support for Borgmatic, Vorta, and Pika Backup integrates the broader ecosystem without glue code.

Key benefits:

• Borg and Restic hosting for the two leading open-source deduplicated backup tools
• Client-side encryption so the server never has access to backup data
• Append-only mode to protect archives from ransomware or accidental deletion
• Backup monitoring with configurable alerts via email, Pushover, or webhooks
• Deduplication and compression to reduce storage footprint and transfer time
• REST API for automating repository creation and SSH key management
• 10 GB permanently free with no credit card required
• Choice of EU or US datacenter for latency and data residency requirements

BorgBase is operated by Peakford Ltd, headquartered in Naxxar, Malta, an EU member state. The service is fully GDPR-compliant, and customers using EU datacenter options keep all backup data within European jurisdiction. Technical support comes directly from active maintainers of the Borg ecosystem.

Ideal for system administrators, self-hosters, and developers who need reliable encrypted offsite backups with transparent pricing and no proprietary lock-in.

Enterprise backup suites such as Veeam, Commvault and Cohesity are supported as targets.
