What it does
One console for your whole backup estate
Everything you need to protect a fleet of machines — without handing your data to someone else's cloud.
Self-hosted & multi-tenant
Runs on your own server and storage. Separate clients, sites, or teams into isolated tenants with their own policies.
Secured with mutual TLS
Every agent enrolls with a client certificate from an internal CA. No shared secrets, no data leaving the encrypted channel.
Deduplicated storage
Content-addressed, chunk-level deduplication keeps repeated data from piling up — your storage footprint stays lean.
Schedules, retention & alerts
Per-set schedules, flexible retention rules, and email or webhook alerting when something needs your attention.
Restore & self-service
Restore files from any point in the retained history. Let device owners run their own backups and restores within limits you set.
Self-updating agents
Roll agent updates out to the fleet from the console — no touching each machine to keep everything current.
Why self-hosted
Your data never leaves your infrastructure
Holdfast Backup is built to run on hardware you control — in your rack, your colo, or your own cloud account. The server holds the keys, the agents talk only to it, and there's no third-party backup vendor in the middle.
