    AVM Initializing Phase

    The backup assistant VM will configure the network, then download and install AhsayOBM. The following status will be displayed in the Notes:

    • INT - AVM tools service is starting up.
    • DCD - AVM tools service is disconnected from CBS via WebSocket.
    • CNI - AVM tools service is connecting to CBS via WebSocket.
    • CND - AVM tools service is connected to CBS via WebSocket.
    • CLD - AVM tools service is connected to CBS via WebSocket and OBM user profile is loaded.
    • RNI - AVM tools service is re-connecting to CBS via WebSocket.
    • RND - AVM tools service is re-connected to CBS via WebSocket.
    • RLD - AVM tools service is re-connected to CBS via WebSocket and OBM user profile is loaded.
    • DLA - AVM tools service is downloading new AVM tools (OBM) packages.
    • UDA - AVM tools service is pending to update.

    CLD Status

    The setup process might take 5 - 15 minutes which depends on several factors like the network, I/O, etc.

    By default, the backup assistant VM will have two hard disks: 10GB and 1TB hard disks with 4GB memory. The 1TB hard disk will be used as a storage area for user data, backups and temporary working space. These hard disk sizes are provisioned sizes, but the total physical disk usage will be approximately 6GB (5GB plus additional 1GB) for a fresh installation of backup assistant VM.

  5. Once the status is CLD, go back to AhsayCBS and click Confirm to finish creating the backup set.
