    "Job Detail" shows suspend-mode backup as "Snapshot"

    When I create a backup job in the Datacenter view and choose the mode "Suspend", the "job Details" incorrectly show the job to be configured in "Snapshot" mode. Is this a bug in the web UI? This line in BackupJobDetail.js seems to be relevant :)
