# 系統損壞災難復原

檢查磁碟陣列狀態 mdadm -D /dev/md0

 移動到陣列上的備份目錄- 檢查備份:`fsarchiver archinfo backup.fsa`

```
cd /srv/dev-disk-by-label-data/SystemBackup/omvbackup
fsarchiver archinfo backup-omv-12-Sep-2019_08-38-27.fsa
```

**以新電腦使用新磁碟，透過網路復原系統**

sudo mount -t cifs -o username=kawsing,password=yourpass //120.115.4.160/systemBackup /mnt

**恢復到新磁碟**，在fsarchiver restfs步驟之前將grub和分區表（**.grubparts文件**）的備份寫入磁盤：

```
sudo apt install fsarchiver
cd /mnt
dd if=backup-omv-12-Sep-2019_08-38-27.grubparts of=/dev/sdx
fsarchiver restfs  backup-omv-12-Sep-2019_08-38-27.fsa id=0,dest=/dev/sdx
```

id = 0表示只是備份中的第一個文件系統將被恢復。我假設您只使用一個備份備份一個文件系統。\
\
重新啟動：`reboot`

```
dd if=backup-omv-19-Sep-2019_12-00-40.grubparts of=/dev/sda
1+0 records in
