Error description

  • When a disk signature of a disk containing a repository changes,
    FastBack driver causes all data written to this disk to be
    discarded. The FastBack server fails to detect this situation
    and does not put the repository in 'limited mode'. As a result,
    it attempts to write snapshot data into the repository, and the
    data is lost, leaving the repository in an unstable state.
    
    After the fix, the server will report SIGNATURE_PROBLEM for
    repository-on-disk (disk signature in location.ini does not
    match signature on disk) or ACCESS_PROBLEM for
    repository-on-volume/folder (access for specified location is
    denied).
