Its another milestone for my computer this month it'll be 4 years since I last rebuilt my RadioDJ database from scratch.
Its been upgraded at least 3 times with new versions and is still going strong, we back it up daily, I've not had to restore a database backup since I switched to a database on the Linux box that's over a year ago now.
Running RDJ in a Windows 10 virtual machine on Ubuntu 18.04 and I really don't appear to have any issues.
Its rare we need to do any maintenance on ours it just chugs along day after day, week after week, year after year!
MariaDB has to take some of the credit... without it I wouldn't have a stable music stream through our Chromecast.
When did you last install your database? How long is it since you last reinstalled/rebuilt things... I'm curious that's all.
Databases fascinate me its the GEEK in me ....
