Heartbeat

A heartbeat is an electronic signal that source nodes send to monitor servers to identify the status of the node.

HOTADD Transport Mode

The HOTADD transport mode is a data transport method that lets you back up virtual machines configured with SCSI disks. For more information, see the Virtual Disk API Programming Guide on the VMware website.

Monitor Server

A monitoring server is a server that verifies the status of source servers in CA ARCserve Central Virtual Standby environments.

NBD Transport Mode

Network Block Device (NBD) transport mode, also referred to as LAN transport mode, uses the Network File Copy (NFC) protocol to communicate. Various VDDK and VCB operations use one connection for each virtual disk that it accesses on each ESX/ESXi Server host when using NBD.

NBDSSL Transport Mode

Network Block Device Secure Sockets Layer (NBDSSL) transport mode uses the Network File Copy (NFC) protocol to communicate. NBDSSL transfers encrypted data using TCP/IP communication networks.

Node

A node is a physical or virtual machine managed by one or more CA ARCserve Central Applications.

Node Group

A node group is a method by which all nodes managed by one or more CA ARCserve Central Applications can be organized, such as by purpose, by OS, or by installed applications.

Policy

A policy is a set of specifications for protecting a node in one or more CA ARCserve Central Applications.

Recovery Point

A recovery pointy is a backup image comprised of parent-plus-oldest-child blocks. Child backups are merged with the parent backup to create new recovery point images so that the value specified is always maintained.

Recovery Point Snapshot

A Recovery Point Snapshot is VMware Virtual Disk (VMDK) or Microsoft Virtual Hard Disk (VHD) files that CA ARCserve Central Virtual Standby creates from CA ARCserve D2D recovery points. CA ARCserve Central Virtual Standby lets you power on virtual machines using Recovery Point Snapshots when the source servers that are running CA ARCserve D2D in your production environment fail.

SAN Transport Mode

The SAN (Storage Area Network) transport mode lets you transfer backup data from proxy systems connected to the SAN to storage devices using Fibre Channel communication.

Virtual Conversion

Virtual conversion is the process where CA ARCserve Central Virtual Standby converts CA ARCserve D2D recovery points from source nodes to virtual machine data files named recovery point snapshots.
