MULTI-CLOUD

When AWS goes down, you don’t

Your infrastructure runs on multiple clouds. When one fails, the others take over. Automatically.

Every cloud has backup. None fail over to another cloud in minutes. Rediacc does.

THE PROBLEM

Single-cloud is a single point of failure

Critical cloud outage events increased 18% year-over-year in 2024, lasted 18.7% longer, and human error caused 68% of them [2]. When your only cloud goes down, everything goes down. Your customers, your revenue, your reputation. All hostage to someone else’s infrastructure.

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 rdc replicate production --target secondary. Incremental sync — only changed blocks transfer.

2

Monitor

Continuous health checks detect failures instantly. Connects to your monitoring stack (Grafana, Prometheus).

3

Failover

Traffic shifts to healthy infrastructure in under 30 seconds. Automatic DNS updates. Zero manual steps.

UNDER THE HOOD

Why cross-cloud replication is fast and cheap

Rediacc uses btrfs send/receive to compute incremental diffs at the filesystem level. Instead of transferring full images, only changed blocks move between sites. A 380 GB environment with 2.4 GB of daily changes transfers 2.4 GB — not 380 GB. That’s a 98% bandwidth reduction. Replication runs continuously or on schedule.

Traditional approach
Rediacc (btrfs send/receive)
Full VM image transfer: 380 GB per sync cycle, hours to complete
Incremental diff: only changed blocks, 2.4 GB typical daily transfer
Vendor-locked replication (AWS to AWS, Azure to Azure)
Cloud-agnostic: any Linux machine to any Linux machine
Manual DNS failover: 15-60 minutes of engineer time
Automated health check + DNS failover in under 30 seconds
Egress fees: $0.09/GB, ~$34/sync for 380 GB full image
Egress fees: $0.09/GB, ~$0.22/sync for 2.4 GB incremental diff
WHY IT MATTERS

What you get

Always online

One cloud fails, another takes over. No manual intervention. Automatic failover triggers on health check failure. Connects to your monitoring stack.

Multi-cloud by default

AWS, Azure, GCP, Hetzner, or your own hardware. Mix and match. Any Linux machine with btrfs can be a replication target.

No vendor lock-in

Move between clouds whenever you want. Open-format snapshots. No proprietary agents. Standard btrfs — in the Linux kernel since 2013.

THE GAP

No other tool fails over across clouds in seconds

Cloud-native tools replicate within their cloud. Backup tools restore hours later. Rediacc replicates across any provider and fails over in under 30 seconds.
