I agree about that line in the documentation being too simple (though it shouldn't deter the technical users here.) They should advise to order a backup drive and compare all the files, or provide CLI instructions to check the safety log file against the one-liner. They seem to provide much better, candid support for hardware issues/safety freezes on reddit, based on what others have posted here, which is cool of them. Contacting support should yield similarly complete answers.
There are some funny stories about Backblaze personally delivering an emergency drive to someone in a remote part of the world, but they don't help the median user.
