  • Each has a real cost: Infrascale Backup & Disaster Recovery reporting dashboard and alerting granularity could provide more detailed proactive alerts; 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: Infrascale Backup & Disaster Recovery covers Instant cloud failover, 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.

Infrascale Backup & Disaster Recovery

  • Reporting dashboard and alerting granularity could provide more detailed proactive alerts
  • Internet dependency critical for cloud-based failover; bandwidth must be managed during uploads
  • Setup and management complexity increases significantly in large and complex IT environments

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

Infrascale Backup & Disaster Recovery: How is Infrascale IBDR pricing structured?

Infrascale IBDR uses aggregated component subscriptions with 1 TB storage increments for consistent monthly pricing. Organizations can lease or purchase physical appliances with flexible payment options.

Source
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.

Infrascale Backup & Disaster Recovery: How fast can Infrascale IBDR recover from disasters?

Infrascale IBDR offers boot-ready failover in minutes with both local micro-disaster recovery on appliances and cloud-based failover with dedicated resources. Automated failback capabilities enable rapid restoration to primary systems.

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.

Infrascale Backup & Disaster Recovery: What systems can Infrascale IBDR protect?

Infrascale IBDR protects physical and virtual machines including Windows and Linux servers, VMware and Hyper-V environments, physical machines and workstations, and Active Directory environments.

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.

Source
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.

Infrascale Backup & Disaster Recovery: Can Infrascale IBDR replicate data to multiple cloud providers?

Yes, Infrascale can replicate to Infrascale's cloud, private cloud, or third-party clouds including AWS, Azure, and Google Cloud. Version 6 includes backup copy options to Amazon S3 Glacier and Glacier Deep Archive.
