I see 2 devices on file. One that backed up successfully approximately 6 hours prior to this post, and another that hasn't backed up in over 2 months. So assuming that the computer you're having the issue with is the latter, I found that the last error message reported was ClientError5. On Macs, this indicates that the backup app is trying to backup broken symbolic links and thus fails as it cannot make sense of a link without an actual file being pointed to.
