Best Backup Software for Azure Storage

Zmanda Pro is an enterprise backup and disaster recovery platform built for organizations that need to keep custody of their own data. It runs as a managed service or entirely on customer-owned infrastructure, including fully offline sites. Backup data moves directly from the client to a storage target the customer controls - Amazon S3, Azure Blob, Google Cloud Storage, Wasabi, any S3-compatible endpoint, a NAS or local disk. Encryption is applied before data leaves the source under a zero-knowledge key model, and immutable retention is enforced through S3 Object Lock, GCS Object Lock or ZFS snapshots. The platform covers 30+ workload types from one console: hypervisors, physical servers, databases, Microsoft 365, NAS appliances and user endpoints. Zmanda Pro is licensed per protected machine rather than by data volume, and air-gapped deployment is software-only with no appliance requirement.
