# 使用rsync復原系統到新磁碟

使用像是gparted live的linux開機

sudo gparted /dev/sda

```
建立類似以下的分割區
Device     Boot     Start       End   Sectors   Size Id Type
/dev/sdj1  *         2048 908398591 908396544 433.2G 83 Linux
/dev/sdj2       908398592 976773119  68374528  32.6G  5 Extended
/dev/sdj5       908400640 976773119  68372480  32.6G 82 Linux swap / Solaris
```

以NFS掛載備份目錄

mount -t nfs IP:/SystemBackup /mnt

```
sudo mount /dev/sda1 /mnt 
rsync -aAXv --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found} root@120.115.4.160:/ /mnt/
cd /mnt
mkdir dev proc sys tmp run mnt media
grub-install --root-directory=/mnt /dev/sda
blkid /dev/sda1 
blkid /dev/sda5
#置換/mnt/boot/grub.cfg的 uuid
#置換/mnt/etc/fstab的/與swap uuid
```

從備份安裝到新磁碟，系統停機，安裝新磁碟，開機到恢復服務花費總時間（16:01\~16:20），花費19分鐘
