MSDB stores backup and restore history. Imagine a server with 2000 databases that takes a log backup of all of them every 15 minutes. That's 192,000 new rows into the backupset and backupmediaset tables EVERY DAY! Keeping a few weeks or months of history can cause the size of MSDB to get very large. 31 мар. 2020 г.
