Depends

Should I use Quorum?

Keep critical systems running with Quorum onQ instant recovery, automated recovery testing, ransomware resilience, and flexible disaster recovery. - quorum.com

· 1 month ago

Fit for organizations running critical on-prem servers that cannot tolerate downtime, often via MSPs. Skip it if you are cloud-only or a tiny team — simpler cloud backup is enough.

Confidence

Low. Based on 9 public sources; most search results describe unrelated 'Quorum' companies (cologne, public-affairs software, cybersecurity services), so product-specific evidence is thin.
