It was a library with 500,000 items being used all the time. I had Librarians who were adding and purging our collection everyday full time and students and faculty checking in and out books etc. all the times.
Insider information all the Library Management Systems are totally broken and garbage (Open Source Evergreen is doing things better). I was required to reboot my Windows Server (Purchased before I was hired) everyday. I was told this was totally acceptable. The Oracle DB was solid but the rest of the stack was total and complete garbage that cost over $125,000 and service contracts of $30,000.
Edit: Off Site aka IT Office Fireproof Case was my monthly and previous weeks. Once a week I walked them over. In the library in a fire case were the daily, and the last week. Tape was it was 2007.
