The short version

  • Each has a real cost: 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.; Veeam Backup & Replication replication propagates corrupted data without detection, as it focuses on speed without extensive integrity checks
  • They diverge on capability: Proxmox Backup Server covers Deduplicated chunk store, Veeam Backup & Replication covers Instant VM recovery.
  • 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.

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.

Veeam Backup & Replication

  • Replication propagates corrupted data without detection, as it focuses on speed without extensive integrity checks
  • Cannot use guest file indexing for snapshot-only jobs, limiting recovery options
  • Multi-factor authentication is not supported for object storage repositories
  • Scale-out backup repositories do not support rotated drives and have limited functionality

Answered from the vendors’ own pages

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.

Veeam Backup & Replication: What is included in Veeam's free tier?

Veeam's free Community Edition supports unlimited backups and replication for up to 10 workloads with the same features as the Standard tier, with no time limit.

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.

Veeam Backup & Replication: How long can Veeam retain backups?

Veeam retention depends on your storage configuration but typically supports retention of multiple backup versions for weeks to years depending on storage capacity and retention policies configured.

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.

Veeam Backup & Replication: Can Veeam replicate data to cloud storage?

Yes, Veeam Backup & Replication supports replication and backup to cloud storage including AWS, Azure, and Google Cloud, with support for object storage repositories and immutable backups.

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.

Veeam Backup & Replication: What hypervisors does Veeam support?

Veeam natively supports VMware vSphere and Microsoft Hyper-V for VM backup and replication, with additional support for physical servers and cloud instances through complementary tools.
