Host Borg and Restic backup repositories with append-only protection, monitoring, and alerts — starting at 10 GB free, with EU or US datacenter choice.
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 repository hosting — the leading open-source deduplicated backup tools
- Client-side encryption — 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 — 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.
