PBS Backup Architecture vs Traditional “Full / Incremental / Differential Backup”

Posted on 2025-11-032025-11-03 by Rico

Q: In PBS, I see many backup entries — which one is a full backup and which one is incremental? This is one of the most common questions people have when they first start using Proxmox Backup Server (PBS): Why are there so many backups, and why does each one look like a “full backup”?Which…

PBS 備份架構 vs 傳統「全備 / 增備 / 差異備份」

Posted on 2025-11-032025-11-03 by Rico

Q:在PBS 上,看到很多備份的資料,到底那一份是完全備份?那一份是增量備份? 這個問題正是很多人在剛接觸 Proxmox Backup Server (PBS) 時的疑惑之一: 為什麼備份那麼多份,但每一份看起來都像「完整備份」?到底哪一份是全備?哪一份是增量? 其實這是因為 PBS 的架構與傳統「全備 / 增備 / 差異備份」完全不同。我們來逐層拆解讓你清楚理解👇 🧩 一、PBS 的備份方式:不是傳統的「全備 + 增備」,而是 去重複快照備份 (deduplicated snapshot) 每一份你在 GUI 上看到的備份(例如 ct/104/2025-10-23T06:02:57Z)在邏輯上都是一份 完整可還原的快照(snapshot)。但在物理上,它只會儲存「與前一版本不同的資料塊(chunks)」。 👉 換句話說: 🔬 二、內部原理:Chunk-based Deduplication PBS 備份時,會將 VM/LXC 的磁碟內容切成很多「chunk」(預設 4 MB 一個),並且對每個 chunk 計算 SHA-256 雜湊值。 流程如下: 所以,雖然你看到有 10 多個時間點: 但實際上: 📦 三、檔案結構舉例 在 PBS 的…

Can Proxmox Backup Server (PBS) Run Inside LXC or Docker?

Posted on 2025-11-032025-11-03 by Rico

🧩 Short Answer ❌ Not recommended, and not supported. Proxmox Backup Server (PBS) is officially designed to run on bare metal or virtual machines (KVM/VM) —not inside LXC containers or Docker environments. ⚠️ Why It’s Not Recommended or Supported 1. System Service Dependencies PBS relies heavily on systemd-managed services — including indexing, garbage collection, authentication,…

Proxmox Backup Server (PBS) 可以裝在LXC 或Docker 中嗎?

Posted on 2025-11-032025-11-03 by Rico

短答:不建議、也不支援。Proxmox Backup Server(PBS)官方設計是跑在 裸機或 KVM/VM 上;不要裝在 LXC 或 Docker。 為什麼不行 / 不建議 可行、被建議的做法 特殊需求的折衷(僅供參考,不保證支援) 總結把 PBS 當成「備份基礎設施」看待:裸機或 VM 才是正途;容器化僅用於備份客戶端。如果你提供你的 PVE/硬碟拓撲,我可以幫你畫一個最小變動、可落地的 VM 方案(含磁碟直通與網路/排程設定)。
