MULTI-CLOUD

When AWS goes down, you don’t

Your apps run across more than one cloud. When one cloud goes down, the others take over on their own. Nobody gets paged.

Every cloud has backups. But none of them fail over to a different cloud in minutes. Rediacc does.

THE PROBLEM

Single-cloud is a single point of failure

Picture this: AWS us-east-1 goes dark and your whole business goes dark with it. Your site, your sales, your support line. All down, and there is nothing you can do but wait. Big cloud outages rose 18% year-over-year in 2024. They lasted 18.7% longer. Human error caused 68% of them [2]. When you bet on one cloud, you bet your business on someone else’s bad day.

Revenue loss: hourly revenue × outage hours. Failover labor: 3 engineers × failover hours × $200/hr × incidents. Customer churn: 20% of direct revenue loss (conservative estimate). SLA penalty: 10% of revenue lost. ITIC 2024 found 41% of enterprises report hourly downtime costs of $1M–$5M [1]. Rediacc’s <30s automatic failover eliminates extended outage windows.
HOW IT WORKS

One command. Always online.

1

Replicate

Run one command: rdc replicate production --target secondary. Only the data that changed moves, not the whole thing. So it stays fast and cheap.

2

Monitor

Rediacc checks your primary site around the clock. The moment it fails, we know. It plugs into the tools you already use, like Grafana and Prometheus.

3

Failover

Traffic moves to a healthy site in under 30 seconds. DNS updates on its own. You do nothing.

UNDER THE HOOD

Why cross-cloud replication is fast and cheap

Rediacc runs on btrfs, the storage engine that makes cheap instant copies possible. It only copies the data that changed since last time. Say you have a 380 GB setup and 2.4 GB changes today. Rediacc moves 2.4 GB, not 380 GB. That cuts bandwidth by 98%. It can run all the time or on a schedule.

Traditional approach
Rediacc (btrfs send/receive)
Copies the full server image: 380 GB every sync, takes hours
Copies only what changed: about 2.4 GB a day
Locked to one vendor (AWS to AWS, Azure to Azure)
Works anywhere: any Linux machine to any Linux machine
Manual DNS switch: 15-60 minutes of engineer time
Automatic health check and DNS switch in under 30 seconds
Data-out fees: $0.09/GB, ~$34/sync for 380 GB full image
Data-out fees: $0.09/GB, ~$0.22/sync for 2.4 GB incremental diff
WHY IT MATTERS

What you get

Always online

One cloud fails and another takes over. No one has to step in. The switch fires the moment a health check fails. It hooks into the monitoring tools you already run.

More than one cloud by default

AWS, Azure, GCP, Hetzner, or your own servers. Mix and match however you like. Any Linux machine with our storage engine can be a backup target.

No vendor lock-in

Move between clouds whenever you want. The saved copies use an open format. No locked-in agents. It is standard btrfs, built into Linux since 2013.

THE GAP

No other tool fails over across clouds in seconds

Cloud-built tools only copy data inside their own cloud. Backup tools take hours to restore. Rediacc copies across any provider and fails over in under 30 seconds.
