我的redis安装似乎使用了大量的磁盘空间。它看起来主要来自这些临时的rdb文件。删除它们安全吗？还有，我可以配置Redis自动删除它们吗？

Redis日志：

9:C 01 Oct 2023 09:35:54.204 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
