Questions
Cloud DR questions: infrastructure recovery answered
Short answer
Twenty-five short answers on cloud disaster recovery for infrastructure, grouped by theme: the basics, buying and pricing, each tool we score, and how this site works. Each answer links to the page that goes deeper. Scores and ranks in the answers are computed from the current data.
What are the basics of cloud DR?
What is cloud disaster recovery?
Bringing cloud services back after an outage, a bad change, an attack or the loss of a region, including the infrastructure, configuration and data they need. See DR basics.
Why is a data backup not a full recovery?
A backup returns data, but a service also needs its network, identity, DNS and settings. Without them the data has nowhere to run. See what a region outage takes.
What is the difference between RTO and RPO?
RTO is how long a service may be down; RPO is how much recent data or change you may lose. See the glossary.
Should I fail over or rebuild?
Fail over for the few applications that cannot wait and can justify a running copy; rebuild from snapshots or code for the rest. See failover or rebuild.
How often should cloud recovery be tested?
Often enough that the path you will use has been run recently. AWS's guidance is that the only recovery that works is the path you test frequently. See recovery region gaps.
Does cloud DR include SaaS settings?
It should. Identity, DNS and paging settings live outside cloud accounts and can break a recovered service. See SaaS configuration.
How do you buy a cloud DR tool?
Which cloud DR tools publish prices?
Arpio publishes every tier, from $12k single-cloud billed annually. Commvault Cloud Rewind has per-instance prices on AWS Marketplace. Firefly publishes Essential at $2,499 a month billed annually, but Backup and DR is Enterprise only, custom priced. ControlMonkey offers a free resilience assessment for up to 50,000 cloud assets; Pro and Enterprise are by quote. Gambit Security lists $1,000,000 per 12 months on AWS Marketplace. Of the tools listed but not scored, Scalr and StackGuardian publish their tiers, and Cohesity publishes no Cloud Rebuild price.
Which tools publish an RTO or RPO?
Firefly states an RTO under 1 hour; Arpio publishes RPOs as low as 15 minutes in Standard and real-time in Premium. Both are vendor claims. The others publish neither on the pages we reviewed.
Which tools document Google Cloud recovery?
Commvault Cloud Rewind and ControlMonkey on the pages we reviewed. Firefly lists Google Cloud for inventory but not in its backup coverage table, and Arpio names Google Cloud as an expansion goal. See multi-cloud coverage.
Do I still need a data backup product?
With Firefly, yes: it does not back up data contents. Arpio and Commvault Cloud Rewind protect data as well as infrastructure, to different depths; ControlMonkey protects configuration only. Cohesity and Veeam are data backup products that work alongside these tools.
What should I ask vendors before a trial?
Which layers they restore, which clouds they support for recovery, how they handle drift, what RTO and RPO they state and how they measured them, and how failback works. See the estimator.
What about each tool?
Which tool ranks first on this site?
Arpio at 7.5 out of 10, then Firefly at 7.3. See the rankings.
Where does Firefly score highest and lowest?
Firefly scores top in the set on bad-change rollback, ties ControlMonkey on rebuild scope and ties Arpio on published recovery targets. Its largest gaps to the top score are on data inside the rebuild and recovery testing. See its profile.
What is Arpio best at?
Orchestrated failover across regions and accounts and failover testing, where it scores top in the set, as it does on pricing transparency. Its gaps are drift detection and change history. See its profile.
Is Commvault Cloud Rewind the same as Appranix?
Yes. appranix.com redirects to the Cloud Rewind page, and Commvault announced the Appranix acquisition on 16 April 2024. See its profile.
Does Cohesity rebuild cloud infrastructure?
For select AWS workloads in Terraform-provisioned environments, through Cloud Rebuild. It is listed with data backup products, which work alongside the tools we score, and is not scored. See its profile.
Is StackGuardian a cloud DR tool?
No. It codifies unmanaged resources and detects drift, which helps before a rebuild, but it describes no recovery product, so it is listed with IaC management platforms and not scored. See its profile.
Are Gambit Security and Scalr cloud DR tools?
Not on their own pages. Gambit's Balens validates recoverability across backups, IaC and cloud; Scalr runs Terraform and OpenTofu with drift revert. Gambit Security is scored because buyers compare it with recovery tools; Scalr is listed with IaC management platforms and not scored.
Why are Veeam and Cohesity not scored?
They protect workload data rather than rebuilding infrastructure, so they are listed with data backup products that work alongside the tools we score. See the rankings page.
How does this site work?
How are the scores calculated?
Each tool gets 0 to 10 on eight criteria; the total is the sum of score times weight divided by 100. See how scores work.
Why does rebuild scope carry the most weight?
Because completeness is half of the question: data restored into an environment that no longer exists does not bring the service back. It carries 20%.
Did you test the tools?
No. Scores come from public vendor pages read on 27 September 2026. Recovery figures are labelled as vendor claims.
Is the site sponsored by a vendor?
No. The weights and every score are published on how scores work, and totals are computed from them.
Can I change the weights?
Yes. The recovery time estimator re-weights the ranking for the incident you worry about most and prints the formula.
How do I report an error?
Use the contact page with the topic Correction and a link to a public source. We check it and update the data, and totals recompute.
