  • They diverge on capability: Amanda Enterprise covers Cross-platform backup, 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.

Amanda Enterprise

  • Minimum 10 workloads required for most use cases
  • Per-device pricing may increase costs for large deployments with many servers
  • Enterprise plan requires contacting sales for custom quotes
  • NAS/File share backups charged separately at $4.99-$5.99/TB/month after first 10 TB free

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.

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.

Amanda Enterprise: Is Zmanda's licensing model flexible?

Yes, Zmanda's licensing is flexible, you can change your server or client license midway if your backup environment changes and only pay the difference. Additional professional services cost $200/hour for consulting.

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.

Amanda Enterprise: What payment options does Zmanda accept?

Zmanda offers multiple payment options including electronic fund transfers (EFTs), wire transfers, and credit card payments with flexible 1-year, 3-year, and 5-year license periods available.

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.

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.
