Back in the late 2000’s I was a windows clustering SME for a major tech company on account with a major financial company. One project I was tasked with was migrating a system which had a huge number of small files. I don’t recall the number. IIRC it took a couple weeks to do the initial file copy. Then the task was to sync the changes during the change window which was 8 hours. Every time I tried to sync the changes it took well more than 8 hours. I did find a tool that could do the job but of course no one wanted to pay for it. Fortunately for me I left that position before the migration and someone else had to figure it out. So yeah, I’ve encountered something similar in the real world. It was the result of poor software design choices but by the time I got there that path was chosen and I had to deal with the results.
