Certain changes to the Job Definition require a full backup for an IR enabled backup instead of incremental.These changes include the following:
  • reset_ir_target_system was run on the IR-enabled target system
  • Reset was run from the BAR Setup portlet on the target system:

    DSC Servers > Systems and Nodes > Systems > IR Support > Reset

  • build_restore_objects was run with the -a|allow_write option on the IR-enabled restore job
  • Build restore objects was run from the BAR Operations portlet:

    From an IR-enabled restore job, select "" > Build Restore Objects

  • run_job was executed with the -a|allow_write option on the IR-enabled restore job
  • Run job with allow write option was run from the BAR Operations portlet:

    From an IR-enabled restore job, select "" > Run Job, then select Allow write for objects after restore.
