Well, if there are error messages due to deterministic causes they are more or less straightforward e.g. you ran out if disk space. For slightly trickier situations where there's either a deterministic cause or at least a highly probable cause we have ALICE, the automated log analyser for failed backups. Anything beyond that is tricky. It requires someone who has the experience reading these log files, understands how Akeeba Backup works under the hood, knows how servers work and can figure out the root cause by seeing what is logged, when and how. In other words, it takes either me or Davide to help with that. That's what you are paying us for :)
