Calculate Your Data Restoration Time
Our Restore Time Calculator helps IT professionals estimate how long it will take to recover data from backups. Understand your Recovery Time Objective (RTO) and identify bottlenecks in your disaster recovery process.
Understanding Restore Time Calculations
Restore time depends on backup size, network bandwidth, disk write speed, and backup type. Full backups restore fastest but take more storage. Incremental restores require processing the full backup plus each incremental in sequence. Understanding these trade-offs is critical for disaster recovery planning.
Restore Time Formula
Restore Time = Backup Size / min(Network Speed, Disk Speed)Why Calculate Restore Time?
Meet RTO Requirements
Ensure your backup strategy can meet business recovery time objectives.
Identify Bottlenecks
Discover if network or disk speed is limiting your recovery capability.
Plan Infrastructure
Size network and storage appropriately for acceptable recovery times.
Compare Scenarios
Evaluate different restoration scenarios from cloud, NAS, or local storage.

Frequently Asked Questions
RTO is the maximum acceptable time to restore business operations after a disaster. If your calculated restore time exceeds your RTO, you need to improve your backup/recovery infrastructure or strategy.
