Proxmox Backup Server (PBS) is your go-to open-source tool for VMs, containers, and bare-metal backups. It’s built on Debian with ZFS support and Rust for speed. 💡

Data deduplication + Zstandard compression save space, while TLS-1.3 and AES-256 encryption keep your backups secure. 🔒

Started in 2018, PBS outgrew vzdump by enabling incremental backups. First stable release in 2020—now it’s a staple for DevOps. 📅

Manage backups via web GUI or CLI, with REST APIs for automation. Prune old data and delete chunks safely to free up space. 🧹

Stick to Proxmox 8.x repos to avoid unwanted upgrades. EOL for 8.4 is late 2026—plan to migrate to 9.x then. ⚠️

Use `apt update/upgrade` for security patches, not `dist-upgrade`. Avoid new repos to stay stable during maintenance. 📁

Balance legacy support with innovation: Extend 8.x lifespan while planning 9.x upgrades. Control your update path! 🔄

Proxmox’s support lifecycle is tied to Debian’s updates. Stay proactive—your infrastructure’s future depends on it. 🚀
