No idea what is causing this and there seems to be nothing online for this precise error, either on Acronis forums or Kaseya. The job has failed twice now constructively.
Similar error was discussed on some Acronis boards and seems to be related to creating snapshots. The error itself is Windows generated, so in the spirit of Microsoft it can have several causes.
Thanks for your quick response Kirk and for the links, I'll check these out.
