I noticed that my server was using a lot more space on local than my Dad's server, and I tracked it down to my Frigate LXC, which isn't currently running but is no. 119, which has created over 7GB of files /var/lib/lxc/119. Every other LXC only has a few KB of files, so why has the Frigate LXC used so much space in this folder and can I delete these files?
