Backup & recovery calculators
Free, browser-only calculators for backup and disaster-recovery planning — replication windows, ransomware cost, and cloud egress. Every calculation runs in your browser; nothing is uploaded, and no account is needed.
RVTools Analyzer
Upload an RVTools export for a browser-local breakdown of VMs, datastores, guest capacity, and hygiene findings.
Open toolReplication window & bandwidth calculator
Check whether replication or restore fits your nightly window over a given link — transfer time, throughput, and margin.
Open toolRansomware & downtime cost calculator
Put a number on an outage: lost revenue, productivity, data-loss rework, and recovery labour, in one transparent estimate.
Open toolCloud backup & egress cost calculator
Compare Amazon S3, Azure, Google Cloud, and ZeroVault — and see what a full ransomware restore really costs.
Open toolFree, private, and vendor-neutral
These calculators are built by BackupSec for backup and infrastructure teams. They are completely free, require no account, and run entirely in your browser — your figures are never sent to a server. The results are vendor-neutral estimates you can share with a link, use in a design, or take into a budget conversation.
