# 運作的系統同步到備用系統

因系統的uuid不同，必須 --exclude=/boot/grub/grub.cfg

```
rsync -aAXv --exclude={/boot/grub/grub.cfg,/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found} root@120.115.4.160:/ /mnt/

```

```
rsync -aAXv --delete --exclude={/boot/grub/grub.cfg,/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/srv/dev-disk-by-label-data/*,/srv/dev-disk-by-id-ata-CT500MX500SSD1_1931E215D99C-part1/*,/lost+found} / /srv/dev-disk-by-id-ata-CT500MX500SSD1_1931E215D99C-part1/
```
