Juju records a longer history in the database, but for ease of debugging we also save to a plain text file, which gets rotated. It is set to rotate at 300MB and save at most 2 backups. Which means it should go to potentially ~1GB but not grow beyond that. We could compress on rotation, which we don't currently do, but it is capped at how much we will save on disk.
