Restored from old S3 backup, but missed a year or so of posts (which is probably not many).
Technically the HDD with TimeMachine has newer MySQL data files, but they are not easy to import. If I could get the 2013 MBP running there’d be more recent data in there.
I later got that computer running, but MariaDB is fucked. The service won’t start, I think a process or file was corrupted when the hardware borked. Even reinstalling it through Homebrew didn’t work. It’s like the earth was salted where MariaDB was.
It might be possible to recover from source data files on backup driving following this information: stackoverflow.com/a/40955339/4783306
