Backup Exec and VCB proxy server configuration

Hello

I am installing Backup Exec to back up my virtual machine on an ESX Server, but I get the following error:

*Backup- VMVCB::ESX01VCGuestVm(DC)ha-datacenter(DC)vmserver03* 


V-79-57344-38220 - Backup of the virtual machine 'server03' failed. VMware VCB framework reported the following error


 


Error: Failed to open the disk: Cannot access a SAN/iSCSI LUN backing this virtual disk. (Hint: Option "-m ndb" swtiches vcbMounter to network base disk access if this is what you want.) 

It's my setup. I have an ESX Server connected to a San. I store my images on the SAN. I have Backup Exec installed on our file server that is also attached to the SAN and try to use this server as my VCB proxy server. I have installed on my server BE VCB framework and the enterprise Converter 3.03. I have setup a temporary staging that the server can access to place its snapshots on.

My BE\VCB proxy server cannot access the SAN LUN that holds the images. My understanding of the process is that of BE I navigate on the ESX Server and select the virtual machine, I want to backup, and because the ESX Server can access the SAN LUNS where VM images are stored throughout the process of alignment of the image and place in the temporary storage area so that BE can then throw tape should work.

Can someone help to solve my problem?

See you soon

Yes, it is the intention of the VCB.  Take the resources needed to run the backup out of the host and on the VCB proxy server.  You can define VCB to use the 'LAN' mode which backs the service console of the virtual computer on the network, but it is slower and puts more pressure on the host.

Make sure you carefully follow the VCB document.  There are some things you need to do on the proxy before presenting the LUN as cutting diskpart automount. If you don't there is a chance that the lun might get corrupted and your VM would go bye-bye.

  • Presentation of ID host ESX host LUN to the VCB Proxy Server

    I have a typical scenario where I have 3 ESX servers with 3 x 800 GB LUNS in a storage group separate on a CX 310 SAN box. The host LUN., of these 3 LUN Ids are 0, 1 and 2.

    I have a specific host that starts from SAN, from the same box of CX 310 SAN. At this point of time, I have no choice to use this server as a Server Proxy VCB. As far as my knowledge goes, LUNS of the ESX servers must be made visible to VCB Proxy Server, as they are presented to the ESX servers.

    My question here is, as the designated Proxy VCB server is booting from the SAN, he already has a host LUN 0 to Id the logic unit number this is the start of. The Id to host ONE of the first 800 GB LUN in the ESX Server storage group is also Host Id 0. Now, if I try to make the LUNS in storage group visible on the VCB Proxy Server ESX, is there not a shock of the VCB Proxy 0 host Id and Id host ESX Lun 0? I'm confused, I don't have a test envirinment where I could try this before I could actually go forward with any solution.

    My intention is to perform a backup outside LAN of the VMDK.

    Any help is that this respect is very much appreciated. Thanks in advance.

    (1) Yes, you can have different host for VCB then for your ESX host LUN ID

    (2) Yes, you can use the identifiers of naa, it will automatically use the identifiers of naa, no need to configure anything at all.

  • Backup Exec and instant / add disk space

    I use Backup Exec to make full VM backups

    After the backup, I can see a snapshot to the virtual machine in the Snapshot Manager

    I deleted all the snapshots of the virtual machine and stop the virtual machine.

    At this point providing drive area is grayed out and e/s can not add disk space on the existing drive

    I don't see that there is a-000001, 000002 vmdk still kicking around in the virtual machine folder

    (a) is it safe to delete the 00001 and 0002?

    (b) any idea how to prevent the creation of the Snapshot Backup Exec files

    Thank you

    Steve

    It is a VM DC

    It turns out that Backup Exec was hung on the VM backup

    Once I canceled the backup, I was able to consolidate

    Thanks for your help

  • How to restore a virtual computer to another computer using Backup Exec virtual

    Hi all

    I tested VMware 3.5.  We have little budget, so we intend to convert 5-10 dev servers into virtual machine running on an existing ML570 HP.  I created a test VM; I could back up and restore the entire virtual machine using Backup Exec to a physical server without problem.  However I can not restore a virtual machine to a different VM.  Let's say I dv01; I backed up using Backup Exec dv01 on the physical server.  Pretending the host has no I have rebuilt a new host, created a new virtual machine with the same name dv01 and same features.  I restored dv01 from the backup.  The restoration is properly; However, he got a blue screen when I rebooted the virtual computer.  The blue screen went so big that I don't remember what it was, but it's the kind of a dll error.

    We want to keep the budget as small as possible using our existing Backup Exec agents, but it doesn't seem to work here.  Is Backup Exec for VMware agent a MUST?  Catering to the same VM is good, but restore to a different VM is not so simple.

    THX.

    As you can see in http://www.vmware.com/products/vi/buy.html, VCB is included in all editions of VI 3.5.

  • How can I make online games access the internet through a proxy server?

    I currently have to use a proxy server to access the internet. I changed my browser settings to do this, but I can't play a game online that I instaled because they are not defined for internet access via the proxy server.
    How can I make games use the proxy server to access the internet?
    Help, please. See you soon!

    Abstergo,
    You will need to have the proxy server configured to allow ports looking for the game or, if the game has the option, you can put in your proxy server information in the parameters of the game.

  • How to uninstall proxy server when no proxy server has been installed

    Several programs to say I am using a proxy server when I'm not (adobe for one). That these programs need a port and an address that I have to reset my PC (somehow) so that these programs can not see the proxy server. IE8 and outlook says I am not using a proxy server and the proxy server setings are grayed out. How can I fix this problem.

    Hi shoe,.

    · What is the exact error message are received?

    · You have security software installed on your computer?

    · What is the service pack installed?

    Check for ISA Server or a Proxy Server that is installed:

    To determine if you have ISA Server or Microsoft Proxy Server installed on your computer:

    a. on the taskbar at the bottom of your screen, click Start, point to settings and then click Control Panel.

    b. double-click Add or remove programs.

    c. list of programs currently installed for Microsoft Proxy Server or Microsoft Internet Security and Acceleration.

    If one of these entries is present, ISA Server or Proxy Server is installed on your computer.

    Looks like you need to install vCentre Converter (the server vCentre himself) of what has been said.

  • Backup Exec 12.5 and VCB - support requirements and agent

    I noticed there is now an agent, which you can purchase from Symantec that allows you to save as many guests on the particular host windows as you want without any agent (though law enforcement officers are still required).

    http://eval.Symantec.com/mktginfo/Enterprise/other_resources/b-solution_brief-bews12.5_agent_vmware_virtual_infrastructure_09-2008.en-us.PDF

    My question is this - from what I can find on the web, ESX 3.5 U3 does not support the latest integration modules Backup Exec (pre and post backup scripts etc.). So based on this, using Backup Exec 12.5 with VCB Symantec agent is needed giving you the GUI (no longer need to customize scripts for VM backups).

    Can someone please clarify this?

    The Agent gives you a GUI with VCB integration. You should always install VCB, just not the integration kit. You can always do it the "old school" way. The modules BE did never seem to work 100% anyway and you can the House push something pre and post if you do not want to pay for the agent.

    I think that VMware just stopped creating integration because the older kits kits are relatively stable. I tested with esx3.5u3/vc2.5u4 and have no problem. There is no update for VCB, so there is no update for the kits.

    I know that you have done this before, then you probably haven't this info, but I just posted a guide on the VI:OPS on VCB as a generic facility backup->http://viops.vmware.com/home/docs/DOC-1392

  • Backup exec 2012, issue of mpio san backup and ALA

    We have a 4 TB File Server 2008, BONE is a physical server with hba to san volume where the files are located on.
    so far, our backup exec server has an hba double iscis, with only using a port in the San.
    in backup exec, I have created 8 jobs that run at the same time and creates 8 snapshots on the san to back up the file server.
    on the side of san when snapshots are created, I can see that snapshots are assigned to the different ethernet ports, eth0, eth1, eth2, eth3, etc..
    and start broadcasting our backup exec Server iscsi hba data, but since it is only using 1 connection her bottleneck through 1 Gbps.

    If I install mpio on the backup exec server and configure the ports and mpio on the hba settings, when the san creates snapshots, the TI separate backups between the two connections of 1 GB on the hba iscis on the backup exec Server?

    what I have to do all the other configurations on the San or switch layer2 (48 1 Gbps connections) that we use for our San?
    I read somewhere that you would have to do something on the switch if you did 'aggregation of links' or 'bonding' but that mpio is completely different, and I wouldn't have to do something for her.

    any comments would be appreciated.

    Hello

    Re: Collage/circuits only is not supported by the MS. iSCSI initiator  It's in the guide to iSCSi Ms.

    RE: iSCSI hba.   What is a Broadcom iSCSI unloading mode or Qlogic iSCSI HBA?

    So once you configure the other port on the DRUNK to be on the same SAN subnet, you can use MPIO.

    You should already have installed the EQL HIT the DRINK server, is that correct?     If so, then run the Remote Setup Wizard in the Equallogic program folder.   There is an option "configure mpio.   Game to use only the iSCSI subnet, and you will see a checkbox for MPIO enabled shadow copy.  Which is enabled by default.

    Kind regards
