VMWare VCB and Networker

I think when the server is a Windows 2003 Server then it should be run.

VCB Proxy have to be a Windows Server!!!

Hello,

I used a Networker server to be a Proxy server, but I have problems. In matrix of VMWare the recommended version is 7.4.1. I try to use this version but networker don't index the vcb backup. Using the version 7.4.0 works but my server stay outdated and I lost many advantages of 7.4.2 Server Version.

I solve this problem creating a Virtual Proxy, is this virtual machine I install the Consolidated Backup, the Legato Integrator and the Networker version 7.4.0, and my server stay with the last and updated version. I add this client in my networker server and use this how proxy backup.

Is the simple way to solve my problem.

This is a config.js file from my client. When you configure a virtual machine works how VBC proxy you need to enable and change the TRANSPORTATION MODE from "san" to "nbd".

If you need more help to understand the environment, I help you.

/*
* TRANSPORT_MODE determines how VCB accesses virtual disk data.
* Currently, two modes are supported on Windows:
*
* +) "san"
* Virtual disk data is read directly off a shared storage device
* that that the virtual disk resides on. This requires VMFS
* storage on SAN or iSCSI and the storage device has to be
* accessible from both ESX and the VCB proxy.
* +) "nbd"
* In this mode, VCB will use an over-the-network protocol to
* access the virtual disk. Data is read from the storage device by
* the ESX host and then sent across an unencrypted network channel
* to the VCB proxy.
* Please note that this mode does not provide the offload
* capabilities of the "san" mode (since data is still transferred
* from the ESX host across the network). However, "nbd" does not
* require shared storage and also enables VCB to be run inside a
* virtual machine.
* +) "nbdssl"
* This mode is same as "nbd" except that the data transfered over
* the network is encrypted. The data transfer in "nbdssl" mode can
* be slower and use more CPU than in the "nbd" transport mode. The
* "nbdssl" mode will fail when connecting directly to ESX 3.0.x
* or VC 2.0.x host.
*
* The default option is "san".

* SNAPSHOT_POLICY determines how disk snapshots for backup are being created:

* Exactly one snapshot named "_VCB-BACKUP_" must already exist for
* each protected VM. The snapshot is mounted/unmounted on the proxy,
* but the snapshot is neither created nor deleted by VCB.
* This can be used to have external tools manage the backup snapshot.
* +) "createonly"
* The Interoperability Module will create the snapshot for each VM
* right before it gets backed up, but will not remove the snapshot
* after unmounting.
* +) "deleteonly"
* The Interoperability Module assumes that the snapshot named
* "_VCB-BACKUP_" has been created beforehand. The snapshot will be
* deleted automatically after backup.

Thanks!

Thank you, but the customer needs to complete the VCB backup via SAN. Obviously, he can't use a virtual machine to realize that.

Do you have some installation with this configuration?
Regards.

Hello,
Does any one have complete VCB setup guide for review, i would recommend Storage node as VCB proxy strongly , unless you are using over the network method so that backups are directed over local tape drives and are more efficiant
