目前deepin23的控制中心里没有系统恢复的入口，只有开机时的Grub启动项中“恢复系统”这一个入口。

系统备份的默认配置文件：

• /etc/deepin-upgrade-manager/ready/data.yaml

target:
  backup_list:
       - "/boot"
       - "/usr"
       - "/etc"
       - "/var/lib/apt"
       - "/var/lib/dkms"
       - "/var/lib/dpkg"
       - "/var/lib/man-db"
       - "/var/lib/initramfs-tools"
       - "/var/lib/systemd/deb-systemd-helper-enabled"
       - "/var/lib/selinux"
  hold_list:
       - "/usr/lib/locale/locale-archive"
       - "/etc/locale.gen"
       - "/usr/share/deepin-defender/localcache.db"
  after_run: "/usr/bin/deepin-upgrade-manager-tool --action=notify"
​

• /etc/deepin-upgrade-manager/config.json

{"config_version":"1.0.11","distribution":"23","active_version":"20220210","cache_dir":"/usr/.osrepo-cache","auto_cleanup":true,"repo_list":[{"repo_mount_point":"/persistent","data_origin":"","repo":"/persistent/osroot/repo","snapshot_dir":"/persistent/osroot/snapshot","config_dir":"/persistent/osroot/config","stage_dir":"/persistent/osroot/cache","Afer_Run":"","Plymouth_Theme":"","subscribe_list":[],"filter_list":[]}],"max_version_retention":2,"max_repo_retention":3}
​

当前备份恢复所用的配置参见 /persistent/osroot/config目录（全盘安装情形下）

系统备份恢复相关的常见命令：

初始化系统备份：sudo deepin-upgrade-manager --action=init

提交系统备份：sudo deepin-upgrade-manager --action=commit

列出系统备份列表：sudo deepin-upgrade-manager --action=list 或省略为：sudo deepin-upgrade-manager

还原指定的系统备份：sudo deepin-upgrade-manager --action=rollback v23.x.x.xxxxxxxx

（更底层一点调用的是ostree命令）

23中没有预装备份软件，你可以下载一个timeshift 备份。
