Verdict
Proxmox Backup Server is the contrarian pick: it delivers incremental, deduplicated, encrypted backups for Proxmox VE and Linux hosts at zero license cost, riding the fast migration away from VMware after the Broadcom price hikes.
What customers praise
Client-side encryption and dedup for no license fee make it unbeatable on cost for Proxmox-native shops.
What customers criticise
Coverage is centered on Proxmox and Linux; Windows, Microsoft 365, and mixed enterprise estates need another tool.
Best for
Teams running Proxmox VE or Linux who want a free, open-source, deduplicating backup server with optional paid support.
