# PBS 安裝在PVE LXC

#### **運行環境**

- **PVE LXC**
- **Debian 12**

#### **LXC安裝PBS**

```
apt update
```

#### **安裝 repo key**

```
wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg
```

#### **新增加 PBS 來源庫**

**編輯`/etc/apt/sources.list`**

```
# 以下是新增加資訊
# Proxmox Backup Server pbs-no-subscription repository provided by proxmox.com,
# NOT recommended for production use
deb http://download.proxmox.com/debian/pbs bookworm pbs-no-subscription

# security updates
deb http://security.debian.org/debian-security bookworm-security main contrib
```

```
apt update
```

```
apt install proxmox-backup-server
```

**註解掉訂閱來源庫 `/etc/apt/sources.list.d/pbs-enterprise.list`**

```
#deb https://enterprise.proxmox.com/debian/pbs bookworm pbs-enterprise
```

**重啟之後瀏覽器登入 `https://ip:8007`**

# PBS ESTALE Stale file handle 解決

**由於PBS掛載的NFS儲存區有搬遷過系統，在掛載時無異常，但是PBS回收作業或是PVE備份作業有ESTALE Stale file handle訊息而失敗**

**PBS錯誤**

**TASK ERROR: unable to get exclusive lock - ESTALE: Stale file handle**

**PVE錯誤**

**unable to get shared lock - ESTALE: Stale file handle**

**可以先嘗試重新掛載**

```
umount /backup
```

```
mount -t nfs -o soft 192.168.0.1:/volume1/file/backup /backup
```

**若依舊錯誤則重啟PBS可恢復**

# PBS namespaces 命名空間

<span style="color: rgb(0, 0, 0);">**當有多台 PVE 使用同一個 PBS，容器有重複VMID時，可能造成備份被覆蓋或是錯誤，可以增加命名空間來區分個別 PVE 的備份**</span>

---

**於PBS網頁上儲存區中新增命名空間**

<span style="color: rgb(0, 0, 0);">**PVE 新增 PBS 時，輸入新增的命名空間**</span>

<span style="color: rgb(0, 0, 0);">**可以為不同的PVE建立不同的空間，每台PVE備份都會儲存到自己的命名空間，不受VMID影響**</span>
