No it doesn't match. Videos of each camera at day time are 1.3GB per 30 mins for each camera. the docker image is growing like 1.5GB per day or something like that.
This are the latest events:
And this is an SCP session I did to verify the files are there:
Also these are the storage options on zoneminder, I haven't mess with that:
I'm thinking maybe these are the logs or the database that zoneminder is saving on the docker image instead of the appdata folder or something like that?
EDIT: I think it's something related to temporary files or something on the docker, just restarted the zoneminder docker and it's down to 1.86GB
