When i unzip it than i can see that is random content from my bookstack instance.

I also see this:

I really doubt that someone export random pages from Bookstack (at least nothing in the audit log - if logged at all). Any idea what that could be?

Steps to Reproduce

I just updated and then a few days later i got the message from my monitoring system that the /tmp is full

Expected Behaviour

It should only create a file when needed. Cleanup old files?
