vRanger 7.8.1 - User Guide

vRanger: installed on a VM

vRanger: installed on a VM

When installed on a VM, vRanger checks the possible transports in the following order, selecting the first option available to ensure the best performance possible.

1	VA on source host: vRanger first checks the source host for a VA. If available, that VA is used.

Is VA-based HotAdd available?: vRanger checks the local VA for HotAdd support. If the host is not properly licensed, or the VA cannot access the storage for the source VM, HotAdd is not available.

 

IMPORTANT: If a VA is configured and HotAdd is not available, a network backup is performed from the VA. No further transport checks are performed.

2	VA on source cluster: If the source host does not have a VA, vRanger determines whether the host is a member of a cluster, If so, vRanger checks for a shared VA on that cluster.

Is VA-based HotAdd available?: vRanger checks the cluster VA for HotAdd support. If the host is not properly licensed, or the VA cannot access the storage for the source VM, HotAdd is not available.

 

IMPORTANT: If a VA is configured and HotAdd is not available, a network backup is performed from the VA. No further transport checks are performed.

3	Machine-based HotAdd: If there is no VA configured, vRanger determines whether HotAdd is available for the vRanger VM. If the vRanger VM is on a host which is not properly licensed, or if the VM cannot access the storage for the source VM, HotAdd is not available.

4	Machine-based LAN: If a VA is not available, and HotAdd is not supported on the vRanger VM, a network backup is performed from the vRanger machine.

vRanger: installed on a physical machine

vRanger: installed on a physical machine

When installed on a physical machine, vRanger checks the possible transports in the following order, selecting the first option available. The preferred transports are checked first, ensuring the best performance possible.

1	VA on source host: vRanger first checks the source host for a VA. If available, that VA is used.

Is HotAdd available?: vRanger checks the local VA for HotAdd support. If the host is not properly licensed, or the VA cannot access the storage for the source VM, HotAdd is not available.

 

IMPORTANT: If a VA is configured and HotAdd is not available, a network backup is performed from the VA. No further transport checks are performed.

2	VA on source cluster: If the source host does not have a VA, vRanger determines whether the host is a member of a cluster, If so, vRanger checks for a shared VA on that cluster.

Is HotAdd available?: vRanger checks the cluster VA for HotAdd support. If the host is not properly licensed, or the VA cannot access the storage for the source VM, HotAdd is not available.

 

IMPORTANT: If a VA is configured and HotAdd is not available, a network backup is performed from the VA. No further transport checks are performed.

3	Machine-based SAN: If there is no VA configured, vRanger determines whether the vRanger server is configured for SAN backups.

4	Machine-based LAN: If a VA is not available, and SAN backups are not supported on the vRanger server, a network backup is performed from the vRanger machine.

Hyper-V backup transport options

Hyper-V backup transport options

When backing up Hyper-V® VMs, backup activity is processed by the vRanger Hyper-V Agent on the Hyper-V host. Backup data is read by the agent and sent from the source server directly to the repository.

When performing backups of Hyper-V VMs, or backup groups containing Hyper-V VMs, the Transport Selection portion of the Backup Wizard is not shown, as there is only one available option.

Physical backup transport options

Physical backup transport options

vRanger transports describe only how data is read from the source server, not how the data is sent to the repository. When backing up physical servers, the vRanger client reads the data directly from the disk and sends data from the source server to the repository. Depending on how the source server is connected to the repository, this process can result in network backups or LAN-free backups. For backups to be LAN-free, the source server and repository must exist on the same SAN.

When performing backups of physical servers, or backup groups containing physical servers, the Transport Selection portion of the Backup Wizard is not shown, as there is only one available option.
