Hi Ryan,

> This surprises me because for all of its faults I was under the impression that Time Machine does at least back up file contents correctly. But I don't know whether an sqlite database is in a consistent state on disk while it is being used e.g. by Buildbot.

Unfortunately, unless you lock your database before a backup, copying/backing up an open Sqlite database file will not work. See https://sqlite.org/backup.html.

Not that I know of any unsupervised way to sanitise a broken buildbot database. But you could have a look at the database yourself and see if there is anything that looks broken and remove those records manually. As you’re on a mac, have a look at Liya https://apps.apple.com/de/app/liya/id455484422?mt=12.
