Ubuntu 20.04 每天生成 tar.gz.1

Ubuntu 20.04 每天生成 tar.gz.1

我在 Google 上进行了大量搜索,并检查了操作系统中的许多文件,但没有发现任何原因。

我有两个目录:

/backup/
/backup2/

以下为每一条内容:

/backup:

的内容/backup2/error与上述完全相同,只不过tar: dump ...由于 而没有-P

/backup/out

it is started at 2022-06-25_02_00_02
it is ended at 2022-06-25_02_05_09

的内容/backup2/dump.sh与上面完全相同,仅backup_path='/backup/'改变了backup_path='/backup2/'

问题出现在大约 48 小时后,并且仅在/backup/路径中,超过 46 小时的文件被重命名,file.tar.gz.1并创建了另一个零字节文件。

我没有 crontab 来执行此操作,并且检查了/etc/cron.hourly/etc/cron.daily但什么也没发现。

我认为这个问题很奇怪,因为只发生在/backup目录中。

您对此问题有什么想法或解决方案吗?
