Best practices for backup of virtual machine.

Hello guys,.

I have a question about the virtual machine snapshot backup option.

In our environment, we use symantec netbackup and it is managed by an administrator of aid. It has implemented the process in a way where the snapshot of the virtual machine is scheduled and then the snapshot is saved in netbackup daily. Once the snapshot backup process is completed, the snapshot is deleted.

My concerns:

1 - remove the snapshot - wouldn't it increase the size of the virtual machine every day?

2 - is enough to restore the virtual machine snapshot disaster?

3. what happens if a virtual machine has a lot of snapshots?

Please help.

A snapshot (delta) file contains only data blocks that have been changed and a reference to their original location in the virtual disk Basic. Maybe http://kb.vmware.com/kb/1015180 helps to clarify this.

  • Best practices for backup of a VM Web server?

    This question comes from another thread, that I created, but I figure I might as well start a thread fresh since it is his own question.

    Basically, I have an environment that I inherited when I started my new job within this environment, there is a lonely VM that runs from our Web server and was created using VMware player (will go to the workstation for the snapshot feature).

    I am extremely concerned by the fact that there is no backup strategy for it, so I'm interested in finding the best way to save this virtual machine.

    Being that it's a machine virtual I instantly thought, but of course I'm open to dictate what best practices.

    A lot of what I've read so far indicates to stop or suspend the virtual machine, then copy files, however is there a way to do that without temporarily take down my Web server?  It's just that we have customers in the world that has access to the server to different time zones and I want her to be in place 24/7.

    You'll have to stop the Virtual Machine and close VMware Player and uninstall VMware Player to install VMware Workstation and it is the time where you should make a backup copy of the master of the Virtual Machine.  Once installed VMware Workstation and the Virtual Machine is back and then runs to reduce the minimum time for subsequent backups you necessarily do not do such proposed by Richardson Porto although I don't disagree with what he says.

    In theory anyway, and in practice, when you want to backup you would take a cliché Hot and then copy the Parent disk such that it is now read-only and the Virtual Machine is still running while you make a copy of the Parent disk.  Once you have copied the Parent disk, you can then remove the snapshot thus merging Delta and drive Parent and now ready for the next time you want to back up the drive.  The duration of that Virtual Machine is interrupted during the snapshot warm and hot snapshot delete should be considerably less and then stop and restart the virtual machine.  The reason why I said "in theory" because while it is supposed to work in practice, nevertheless if you correctly shutdown the guest operating system before capture instant, so you do not rely on VMware Workstation to make sure that everything works all in being hot.  Not that you should have problems, it's hot, however you remove a layer of the process that has the potential of being wrong compared to when is cold, even if it is cold takes a little longer.

    In both cases, I would avoid cloning because it changes the UUID and MAC address of the clone of the parent company and by creating a second occurrence technically need a second license for the Windows operating system that is installed on the cloned virtual machine.  In other words an archived copy complete or exact unedited from the original is a legitimate backup a clone of IMO is a second occurrence but it has a different UUID and MAC address.  It would be like taking a copy of the operating system with a single license and install on two different physical computers.  Also by doing as I have suggested and make a backup copy of Master of the Virtual Machine and then just save the Parent read-only disks disk hard virtual are themselves not a computer virtual and just that copy a backup, however can be used to restore the same Virtual Machine driven and not having not any changes in the UUID MAC addresses etc.

    Finally, you should look into what you are running in the guest operating system and how to properly save Web Site and database, or user data etc in the guest operating system.  In other words, you should always have a copy backup of the virtual machine and everything that is necessary in the guest operating system to be able to restore it without necessarily restore all of the Virtual Machine.  IMO it's better to have several and backup types to have more options in a recovery scenario!

  • What is the best way to backup of virtual machines on a standalone ESX with the data store local

    Hello

    I want to save the virtual machines on a host ESX autonomous. and all of these virtual machines is the local data store.  What is the best way to save these virtual machines in this situation?

    And probably we don't provision VTL on the local data center, so it is possible to use VCB to backup? And VCB is a good choice compared to the traditional method that installs the backup client in each virtual machine?   Because I think that in this situation with the data store local, it cannot not reduced the load on ESX hosts and network overhead can be avoided.

    Thank you!

    LAN

    > 1. VCB usable remote tape library? I mean it's not local library and uses the tape library to another network data center.

    VCB is completely unrelated to the tape library, it is a framework, not a backup solution. If your standard backup software can work with the remote tape library you can try it to ungrateful with VCB.

    > 2. what the difference bwteen hot - added NBD and modes if there is that an ESX host with store data local and want to use a virtual machine like VCB proxy? I think that they are the same: the VCB proxy read data through the I/O of the ESX host stack in this situation.

    NBD works on network and the backup traffic goes through the service console connection. Hot add uses special machine for assistance to connect vmdk to and uses of e/s disk stack instead of e/s network.

    > 3. Veeam Backup is free software?

    No, it isn't.

  • Best practices for backup service console configuration

    Hello

    When you install our ESX servers, I did what I thought was best practices and created a "backup" vswitch with a second service console. Two service consoles have IP addresses on the same subnet.

    They work very well for several weeks. But today, I had a problem connecting to the consoles of the virtual machines on one of our ESX host. After much troubleshooting, I found doc below...

    http://KB.VMware.com/selfservice/viewContent.do?language=en_US & externalId = 749640

    In point 8, it is said to make sure that you do not have 2 consoles of service on the same network. (Either by the way once I removed the backup vswitch I could access the consoles.)

    I so wanted to check this - should I not create these backup service consoles?

    TIA,

    H

    You don't have to second service console, just a second link to SC.

    Add a NIC to portgroup SC (it can be standby NIC), which would be enough.

  • AppAssure best practices for the storage of machine image

    I work in a regulated environment where our machines are validated before being put into service.  Once they are put in service, changes to the machines are controlled and executed by a process of change request.  We use AppAssure to back up critical computers and with the ' always on ' incremental backup, works very well for the restoration of level file/folder in the case where something is removed, moved, etc..

    Management process asks me to perform once a machine is validated, to take a picture of it and store the image further so that if there is a hardware failure, the validated image can be restored and the machine is essentially to it of original validated state.  In addition to having the image of the machine as soon as it is posted, I need to also back up the machine on a regular basis in order to restore files, folders, databases, etc. on this machine.

    So my question is how to achieve this with AppAssure?  My first thoughts are to perform the backup of the machine Base, then archive it, and then let the AppAssure to perform the scheduled backup.  If I need to restore the computer to the Base image, then I back the Archive and then do the restore.  Is this a feasible solution and practice?  If this isn't the case, please tell us the best way I could accomplish what I want to do.

    Thank you

    Hi ENCODuane,

    You can carry out the plan of action of the WES in the following way

    1. to protect the agent with the name "[Hostname\IP_Base]".

    2. take the base image.

    3 remove the protection agent, but let the recovery points

    4. After these steps, you will have recovery basis point for the agent in the section 'recovery only Points.

    5. go to the agent computer, open the registry and change the ID of the Agent (a sign of evolution will be enough).  HKEY_LOCAL_MACHINE\SOFTWARE\AppRecovery\Agent\AgentId\Id

    for example, of

    94887f95-f7ee-42eb-AC06-777d9dd8073f

    TO

    84887f95-f7ee-42eb-AC06-777d9dd8073f

    6. restart the agent service

    7. from this point core Dell-AppAssure will recognize machine as a different agent.

    8 protect the machine with the name "[Hostname\IP]".

    If after these steps, you'll Base image for the 'Recovery only Points' machine (with the name "[Hostname\IP_Base]" which will not be changed by the update rollup and transfers) and protected the machine with the name "[Hostname\IP]" where the transfers will be made based on configured policy.

  • Best practices for backup of vCenter device and ESXi hosts?

    Hello

    I have a new VMware environment based on 5.5 ESXi and vCenter Server Appliance. A few questions:

    • What is the best practice to perform the backup of the vCenter Server Appliance? I set up the camera with the embedded SQL Express database.
    • It's recommended to backup the ESXi host or is it easier to any re - install failure?

    Best regards
    ,

    Hello

    You can use VMware VDP to backup your device of vCenter. It is included in essentials, standard, enterprise, and enterprise as well as licenses.

    I won't have backups of ESXi servers. Restore the backup would take more time that the deployment of a new ESXi.Only thing, you may want to consider is to enable logging remotely, so you can see why the hosts failed.

  • VMware has a guide of best practices for backup of VMware View & DR?

    How to properly protect a server with VMware View VMware vSphere running? Our RPO/RTO is ideally < 2 hrs?

    We have 100 customers and we use a roaming profile. TIA

    Hello

    Haven't seen specific guides. There are a few examples of 3rd party that might give you some ideas. VCenter Heartbeat also supports the component View Composer.

    Little old (2009), but interesting to read:

    http://www.EMC.com/collateral/software/technical-documentation/h6534-business-continuity-VMware-view-Celerra-VMware-SRM-blueprint.PDF

    Maybe the next version of view could address this? If you use roaming profiles, and then you just a way to replicate users DR and point to the DR View Pool, failover would take only a DNS change. Dealing with linked clones and persistent readers makes many tricker.

    I would consider the XP VM to throw objects, is the user customization, you need to reproduce for them in DR.

  • Best-practice for hardware virtualization?

    Hardware virtualization is disabled by default when I create new virtual machines in my VMware clusters. But what are the best practices for this what settings are recommended? Are there reasons NOT to activate the hardware virtualization?

    IMO there is no advantage in allowing virtualization of hardware if you have no need for the virtual machine (for example, a virtual host of the ESXi).

  • Best practices for network configuration of vSphere with two subnets?

    Well, then I'll set up 3 ESXi hosts connected to storage shared with two different subnets. I configured the iSCSI initiator and the iSCSI with his own default gateway - 192.168.1.1 - targets through a Cisco router and did the same with the hosts configured with its own default gateway - 192.168.2.2. I don't know if I should have a router in the middle to route traffic between two subnets since I use iSCSI ports linking and grouping of NETWORK cards. If I shouldn't use a physical router, how do I route the traffic between different subnets and use iSCSI ports binding at the same time. What are the best practices for the implementation of a network with two subnets vSphere (ESX host network: iSCSI network)? Thank you in advance.

    Install the most common iSCSI would be traffic between hosts and

    the storage is not being routed, because a router it could reduce performance.

    If you have VLAN 10(192.168.1.0/24) iSCSI, VLAN 20 (192.168.2.0/24) ESX

    MGMT and VLAN 30 (192.168.3.0/24) comments VMs and VLAN 40 (192.168.4.0/24)

    vMotion a deployment scenario might be something like:

    NIC1 - vSwitch 0 - active VMK (192.168.1.10) MGMT, vMotion VMK (192.168.4.10)

    standby

    NIC2 - vSwitch 1 - current (VLAN30) guest virtual machine port group

    NIC3 - vSwitch 2 - active VMK1 (192.168.1.10) iSCSI

    NIC4 - vSwitch 2 - active VMK2 (192.168.1.11) iSCSI

    NIC5 - vSwitch 1 - current (VLAN30) guest virtual machine port group

    NIC6 - vSwitch 0 - MGMT VMK (192.168.2.10) standby, vMotion

    VMK (192.168.4.10) active

    You would place you on VLAN 10 storage with an IP address of something like target

    192.168.1.8 and iSCSI traffic would remain on this VLAN. The default value

    gateway configured in ESXi would be the router the VLAN 20 with an ip address of

    something like 192.168.2.1. I hope that scenario help set some options.

  • vSpere 5 Networking of best practices for the use of 4 to 1 GB NIC?

    Hello

    I'm looking for a networking of best practices for the use of 4-1 GB NIC with vSphere 5. I know there are a lot of good practice using 10 GB, but our current config does support only 1 GB. I need to include the management, vMotion, Virtual Machine (VM) and iSCSi. If there are others you would recommend, please let me know.

    I found a diagram that resembles what I need, but it's for 10 GB. I think it works...

    vSphere 5 - 10GbE SegmentedNetworks Ent Design v0_4.jpg(I had this pattern HERE - rights go to Paul Kelly)

    My next question is how much of a traffic load is each object take through the network, percentage wise?

    For example, 'Management' is very small and the only time where it is in use is during the installation of the agent. Then it uses 70%.

    I need the percentage of bandwidth, if possible.

    If anyone out there can help me, that would be so awesome.

    Thank you!

    -Erich

    Without knowing your environment, it would be impossible to give you an idea of the uses of bandwidth.

    That said if you had about 10-15 virtual machines per host with this configuration, you should be fine.

  • Best practices for vSphere 5 Networking

    Hi all

    Given the following environment:

    (1) 4 physical servers, each server has 16 (Gigabit) network interface cards will install vSphere 5 std.

    (2) 2 switches with SAN storage battery function

    (3) 2 Equallogic PS4000 SAN (two controllers)

    (4) 2 switches for the traffic of the virtual machine

    As for networking, I intend create some vSwitches on each physical server as follows

    1 vSwitch0 - used for iSCSI storage

    6 network adapters are associated with IP-hash, multitracks with iSCSI Storage consolidation policy. and storage load balancing is round Rodin (vmware)

    (vmware suggests to use 2 cards for 1 traget of IP storage, I'm not sure)

    2 vSwitch1 - used for the virtual machine

    6 Teamed network adapters for the traffic of the virtual machine, with the hash intellectual property policy

    3 vSwitch2 - management

    2 network cards are associated

    4 vSwitch3 - vMotion

    2 network cards are associated

    You would like to give me some suggestions?

    Alex, the standard set by the storage and VMware is used by dell for their servers and tested sound on their equipment and the publication of the document, it is recommended...

    This sound is the best practice for dell server with this model mentioned in the document to use.

    Hope that clarifies...
