  • Only Proxmox Backup Server has a free tier, so it costs nothing to try first.
  • Each has a real cost: Axcient x360Recover sMR hard drives not supported and cause severe performance degradation; 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: Axcient x360Recover covers Chain-free 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.

Axcient x360Recover

  • SMR hard drives not supported and cause severe performance degradation
  • Maximum 100TB per protected system in Axcient cloud storage
  • Limited recovery operations for systems using 4K disks (mount, iSCSI, and bare metal only)
  • Licensing model is complex and confusing, requiring careful mapping of servers versus workstations

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.
