Nextcloud asked in a poll at https://mastodon.social/@nextcloud@mastodon.xyz/115095096413238457 what database its users are running. Interestingly one fifth replied they don’t know. Should people know better where their data is stored, or is it a good thing everything is running so smoothly people don’t need to know what their software stack is built upon?
Look into it, it’s pretty good.
And Apple updated hundreds of millions of devices to it from an old file system without losing any data. Imagine Microsoft pulling off such a migration. It was silently done in the background with a normal OS update. Really impressive.
