Consider whether you want a fully managed cloud service or a platform that also covers on-premises and other cloud workloads. Check retention options, recovery granularity, and any compliance or data residency requirements your organization has. If you are an MSP, look for multi-tenancy and centralized management features. Evaluate pricing models, such as flat-rate versus consumption-based, against your expected data volume. Finally, review each vendor's security architecture, including immutability and air-gap capabilities, to match your risk profile.
