Good, that answered some of my queries.
Now as root again, paste the output of a comparative usage of the directory 
structure immediately above where the files were that you deleted.

For example if you have

/media/archives/2021/march/january
/media/archives/2021/march/february

then execute

du -s /media/archives/2021/march/*


/media/archives/january
/media/archives/february

then execute

du -s /media/archives/*


expect an output that ends with a 'january'

root:/home/marc# du -s /media/archives/*
9913216   /media/archives/january
43905428  /media/archives/february
219244    /media/archives/march

I cannot make the following judgement, hopefully you can.
Compare the directories usage, as you know their expected contents determine if 
it makes sense.
An extra 200GB somewhere should stick out like a sore thumb.

Once you are certain where the extra usage is, you can work on that directory 
alone.
My very first check would be sorting by size including .dotfiles


ls -alrS /media/archives/january

The difference in space used as shown by 'ls' and by 'du -s' is very 
minimal and can be explained by the fact that 'ls' does not take 
allocation block size into account, but 'du -s' does.
