The short version

  • Only Proxmox Backup Server has a free tier, so it costs nothing to try first.
  • Each has a real cost: Druva Data Resiliency Cloud no published pricing, all plans require custom quotes making cost comparison difficult; Proxmox Backup Server there is no Windows client, so physical Windows machines must be backed up by something else and the estate ends up with two backup products.
  • They diverge on capability: Druva Data Resiliency Cloud covers 100% SaaS architecture, Proxmox Backup Server covers Deduplicated chunk store.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Druva Data Resiliency Cloud

  • No published pricing, all plans require custom quotes making cost comparison difficult
  • Requires assessment and setup time before deployment
  • Limited detail on RPO/RTO for on-premises workloads compared to cloud-native recovery
  • Consumption-based pricing can make costs unpredictable for growing data volumes

Proxmox Backup Server

  • There is no Windows client, so physical Windows machines must be backed up by something else and the estate ends up with two backup products.
  • The datastore is millions of small chunk files, so it needs storage with real input and output capability and performs poorly on a single spinning disk or an SMB or NFS share.
  • Deduplication is per datastore, so splitting workloads across datastores for retention or tenancy reasons multiplies the storage those workloads consume.
  • Garbage collection depends on file access time semantics on the underlying filesystem, so a datastore mounted with the wrong options can fail to reclaim space or, worse, behave unpredictably.
  • Subscriptions are priced per CPU socket per year, so a backup server consolidated onto fewer larger dual socket machines pays twice per host for the supported repository.

Answered from the vendors’ own pages

Druva Data Resiliency Cloud: What is the pricing model for Druva Data Resiliency Cloud?

Druva does not publish pricing. All plans are custom-quoted based on data sources protected, data volume, and retention period. Median annual contracts reported by Vendr are around $19,400, with ranges from $3,800 to $52,600+.

Proxmox Backup Server: Can it back up machines that are not on Proxmox?

Linux hosts yes, through the client, at file level. Other hypervisors and physical Windows machines are outside its scope.

Druva Data Resiliency Cloud: What recovery time and point objectives can Druva achieve?

Druva customers can achieve RPO (Recovery Point Objective) as low as one hour and RTO (Recovery Time Objective) in minutes. Cloud-DR functionality can instantiate VM copies in the cloud within minutes.

Source
Proxmox Backup Server: Is a subscription required?

No. Without one you use the community repository and forum support. The subscription buys the tested enterprise repository and vendor tickets.

Druva Data Resiliency Cloud: What workloads does Druva protect?

Druva protects endpoints, cloud workloads (AWS, Azure, Microsoft 365, Google Workspace), on-premises servers, and provides backup, disaster recovery, archival, and eDiscovery capabilities.

Source
Proxmox Backup Server: How do I know a backup will restore?

Run verification jobs. They re-read the stored chunks and mark snapshots verified or failed, which is stronger evidence than a successful backup log.

Druva Data Resiliency Cloud: Does Druva offer immutable backups?

Yes. Druva provides air-gapped and immutable data protection to prevent ransomware attacks and ensure data integrity.

Proxmox Backup Server: What storage should the datastore be on?

Local disks, ideally with ZFS and enough input and output capacity for many small files. Network shares are supported but routinely disappointing.

Druva Data Resiliency Cloud: What features does Druva include?

Druva includes advanced anomaly detection for early threat identification, single unified platform for multiple data sources, and air-gapped immutable backups for ransomware protection.
