2023-06-14 08:37 deepin 自己摸索了一个傻瓜的方案：
- copy 一份timeshift默认的配置，并更改为自己的配置timeshift-data.json
这里的磁盘uuid我选择了另一个磁盘，防止一块磁盘突然损坏导致数据丢失，只备份数据排除其他所有内容。
系统备份有默认的timeshift定时任务。
第一次备份的话，do_first_run要改为true,注意这里需要修改为自己存储备份磁盘的uuid,输入blkid查询

timeshift如何按不同配置备份呢？实现系统和数据分开
timeshift默认的配置文件在/etc/timeshift/timeshift.json
而我想实现系统和数据分开备份，这个就需要同时运行两个任务。
似乎没找到命令行可以指定配置文件的相关文档。
如：
sudo timeshift --create --comments "new backup" --config /etc/timeshift/data.json --tags D --snapshot-device /dev/sda1
