Backup of virtual machines with question VCB

Hi all

When you backup a VM with VCB and it has the virtual disk that are size fixed say 100 GB, does that mean when you save this VM with VCB, you will need 100 GB of space to back that up?  If this is the case is that you can set VCB to backup the virtual drive but only backup, which is acutally used anyway.  Say so, you have a virtual machine with 100 GB fixed disk but it only really uses 20 GB of available space is possible to get VCB to backup only the 20 GB of the virutal disk or you must take it all when it comes to a fixed disk?

As long as you drop the flags of the export, you will get a backup of only the space used for a backup of fullvm. SO, in your example, you have a backup of a little more than 20 GB, 100 GB.

Flags of the export drive:

-M: If, together, the disk is exported in a single file (monolithic).

When it is off (default), the disc is divided into several files of 2 GB.

-F: so together, the disk is exported in the form of disc "flat", with no optimization.

When it is off (default), the exported files disk will be more compact than

unused space in the disk image is not included in the exported file.

  • Problem with VMTools & backup of virtual machines

    Hello

    I can't back up some virtual machines with installed VMTools. Once I have remove VMTools machine virtual back ok.

    I get the error message is as follows for virtual machines with VMTools installed:

    e000954c - an error occurred while executing the command "vcbMounter" of VMware to save a virtual machine. See the backlog for more details.

    I use VCB 1.5 update 2 & Backup Exec 12.5.

    Have you tried to disable the SYNCHRONIZATION driver in just by using VSS and VMware tools or vice versa?

    How do you do that?

    The installation of VMware tools on a virtual machine and choose the option 'Interactive '.  Choose the option "Edit", and then expand the section "VMware device drivers.  On the Windows Server 2008, simply look for the "Volume Shadow Copy Service Support" option.  On the Windows 2003 server, locate the VSS and the SYNCHRONIZATION options or file system synchronization driver.

  • Photos of virtual machines with multiple disks on different LUNS - Question

    I have some questions on how to manage the snapshots of virtual machines with multiple disks on different LUNS.  First of all, the LUNS are VMFS.  We are just starting to add virtual machines with dedicated for data storage format VMFS LUNS.  I don't think an extra space must be made for snapshots, as well as at least 100 GB LUN is required to store the data, and then say, add about 25 to 50% of this amount?  Set the 100 GB vmdk file but have the GB from 25 to 50 additional disk space for snapshots, if necessary (rather than just to get a unit number logic needed 100 GB of data and devote all of the 100 GB to the vmdk file).  In addition, if a virtual machine has several files vmdk on different LUNS, which will be a problem to take a snapshot, and is it possible to do just a snapshot of a disk of a virtual computer (as the volume of the BONE)?

    Thanks for any help.

    Snapshot files are created in the home folder of the VM by default for all virtual disks, no matter on what data store they are. You must make sure you have enough free disk space on the data store for snapshots.

    If you want to exclude a virtual disks of taking snapshots, you can set it to 'Independent' - 'Persistent' machine virtual settings to the HARD drive.

  • Run a virtual machine with a graphical interface on a host without GUI

    Hallo

    I want to install a simple Windows 7 for some tasks bit where I need Windows on my server Ubuntu 14.04. This server has no GUI (no X) and should have any.

    Already, I've installed the virtual Windows machine on my workstation to 12, so I would just copy the vmdk on my linux server and run it, maybe put something in the vmx file.

    But I do not know is that it's all means possible.

    Is it?

    Is there any player or any application for ubuntu VMware when there is no X system (on ubuntu), where I can run virtual machines with GUI inside?

    Maybe another virtualization tool, vmware not?

    I think that this exact question already somewhere, but I haven't found much question where comments lacking a GUI, but not the host.

    I need a guest-gui on a host without gui (where I have only the terminal).

    So maybe it's not possible at all, so please tell me a 'no', so I won't expect more

    Thank you to

    Frank

    EDIT: oh, this seems to be another question unanswered it is too difficult or too stupid?

    Hi Frank,.

    Now that would be stupid, having a text Installer, and then not allow the virtual machine to run. I think it should work, but you must pass the nogui option.

    Vmrun help:

    beginning

    (Supported only on teams

    Workstation.)

    Starts a virtual machine (.vmx file) or team (file .vmtm).

    The default graphical user interface option starts the machine in an interactive way,

    What is necessary to display a user interface of VMware.

    Nogui option suppresses the user interface,

    including start-up, to allow dialog box not interactive

    writing scripts.

    [gui | nogui]

    refer to the manual of vmrun: VIX API Documentation

    Edit: hmm... Now, I see that you have already tried the nogui option. You might be able to install the package libxinerama, but he could hang out in a lot of dependencies.

    FWIW, vSphere is pretty much what you describe a system not GUI to run GUI invited, so it shouldn't be a problem at all.

    Unfortunately, I don't have a host linux without X installed handy here, so can't test here without the implementation of a server without head myself.

    You can also try to run the client via the command vmware:

  • Using filters and Get - view to find virtual machines with a specific guest operating system.

    I have the following code snippet to find all virtual machines with the updated OS to ' Red Hat Enterprise Linux * "prompt. It does not work. If the filter is left out, I find myself with all virtual machines.

  • Create the virtual machine with the ISO mounted CDROM

    Community of hell!

  • How to export/import a virtual machine with ESXi 5

    I use the free version of ESXi 5 and have created a virtual machine that is configured with the software for our project. I would like to share this virtual machine with other members of the team, some of whom are in other places and have slow network connections.  I want to pack the VM in a reasonable size file or a set of files I could ftp (or put it on DVD for people in areas of slow network) that they could then import into their ESXi hosts. The virtual machine has a 60 GB drive that is implemented by using the option 'thin', so it contains only 6 or 7 GB of real data right now.  Is it possible to export the image to a file or set of files that can be imported to another people ESXI host?  Before when I used VM Player we could do this by upgrading backup files in virtual machine directory and copy them to the new machine. With the ESXi data store, I don't know that something like this can be done.  I used vCenter Converter to convert to ESXi Infrastructure VM in VM Player format (and vice versa), but it is extremely slow. I think I might point the Source to my ESXi host and the Destination to a co-workers ESXi host and run a 'conversion' to transfer the files, but I think it would be very slow and impractical for some people to 'slow-network '.  I tried with vSphere Client navigation data store and I see the download options, but when I tried to download a VM directory it just hung.  I enabled ssh on my server ESXi and I found the store of data under/vmfs/volumes and when I look in the folder that contains my VM, there a file myvmname - flat hard which is 60 GB in size, so if I tar the contents of this folder to move elsewhere it will be huge.

    Can anyone suggest a solution?  The licensed version of ESXi would offer better alternatives?

    You can watch export OVF available in the Client vSphere for this function.

  • Backup of virtual machine using iSCSI Server

    As the title says.

    I (MSA 2312i) iSCSI storage and Im going to do install a backup on a virtual computer product.  To achieve LAN free backup, I think I need to create the virtual machine with two network cards.  One on the production of LAN and the other on the iSCSI network?

    I have a NETWORK card physical free that I can create a Virtual switch with a VMKernel port and then add it to the virtual machine, it would be the best solution?

    Thank you

    Yes the iscsi network, where by it would also be the LAN backup.

  • Doubts about sound in the virtual machine with w2k3

    Hi all

    I have the following question on the sound:

    • In my lab I have an ESXi 4.1 without sound card.
    • I create a virtual with Windows Server 2003 computer.
    • When I connect to my VM via Remote Desktop, I hear the typical sound of logon of windows acroos the speakers of my laptop. Why, if my VM doesn't have a sound card?
    • What kind of sound can reproduce via Remote Desktop if the server has no sound card?

    If anyone can clarify on this, I'll be very grateful

    Thank you

    Hello febsa

    The virtual machine with W2003 used your computer speakers.

    What kind of sound can reproduce via Remote Desktop if the server has no sound card? Only the default Windows 2003 sounds


  • Pre-built virtual machine with OBIEE and APEX

    Hi all

    I searched for a virtual machine with OBIEE and APEX pre-installed, but I can't find it... or information messages on this subject. Does anyone know if y at - it a selection of pre-designed developer programs VM with these two tools?
    I currently have the "database App Development VM' with APEX in there, but I can't understand how to install OBIEE inside.

    Any help will be appreciated.

    Please, if this is not the right category where I should ask the question, let me know and I'll move it.

    Thank you.
    Elena.

    PL see deployment guide in the link above - the model of computer virtual includes version of database 11.2.0.3, which should be the APEX installed by default in it. If this isn't the case, it will be much easier to install the APEX in the VM OBIEE.

  • Backup of virtual machines really necessary?

    Hello

    I have a few virtual machines running with Windows. I save the machines under windows in the form of images. From the images, I can possibly restore the entire machine or single files.

    So, when my machine goes down I could create a new machine in ESXi and restore from my backup image.

    Does make sense to make a parallel backup virtual machines with free solutions described in this community, because if I would back up my data twice.

    Is that not wrong? What is your opinion?

    Concerning

    Peter

    There is only one hardware requirement, in the new virtual machine u must use the hard drive of the same size or more, but not smaller than the disk of the failed computer, performance differences are few

  • Migrate a virtual machine with snapshots.  Works?
