我使用的是 16.04。可用磁盘空间每小时都在减少，单位是 GB。我没有下载或安装任何东西。
昨天我运行了 timeshift，恢复了 20GB 以上的可用空间。今天早上又出现磁盘空间不足的情况。我在 timeshift 上进行了第二次系统恢复，我正在监控可用空间，发现它又在快速消耗。
我运行了磁盘使用情况分析器，但我不确定哪一个正在变得越来越臃肿。
我删除了文件、垃圾和应用程序，但可用空间并没有增加，直到我进行系统还原。
这可能是什么原因造成的？

我使用了最后一部分。到目前为止，日志文件没有增长。
sudo apt-get install busybox-syslogd
安装该软件包后，重置 syslog 和 kern.log：
sudo tee /var/log/syslog /var/log/kern.log </dev/null
谢谢大家
