  • Creating VM in local ESXi datastore for backing up VM from SAN datastore

    Hi All,

    I'd like to know how did you configure your backup server as a VM ?

    my idea is to utilize the local VMFS3 datastore on my 3x ESXi servers,
    by installing the 3rd party application (like Veeam Backup 5 or Backup Exec 2010) into Windows Server 2008 R2 VM
    equipped with very big hard drive size (8 GB OS + 1 TB data partition VMDK) on each of the local datastore to backup the VM inside the SAN.

    What I've got:
    VMware vSphere 4 Essential - ESXi 4.0 (no hot add)

    Dell Power Edge 2950 with 2.5 TB multiple VMFS3 extent on top of - RAID 5 (6x 500GB SATAII 7200rpm)
    Dell MD3000i iSCSI SAN over Gigabit Ethernet

    The Windows Server 2008 R2 VM configuration:
    2x CPU @ 2.33 GHz
    4 GB RAM
    VMXNet3 NIC --> for better connectivity of the backup between the local ESXi datastore and the iSCSI-SAN datastore.

    Here is the reason I'm doing this is that:
    1. I don't have the extra NIC to connect my physical server into the iSCSI SAN switch, therefore i can't use -SAN backup mode.
    2. I only use the lowest VMware license available which doesn't support hardware Hot-add feature.

    Would this be optimal configuration ?

    Any kind of help and suggestion to implement VM backup as VM would be greatly appreciated.

    Thanks.

    You want to perform disk-to-disk backups? Does your software allow this in your current license? Many times a separate license is required for D2D backup.
    Do you intend to install backup agents in the VMs?
    If you can afford vSphere Essentials Plus, you'll get VDR; or you can indeed buy Veeam Backup.

    I used VDR in the past, a little bit different scenario, but we had a VDR machine with a big disk (physical RDM, not VMDK) and it used to backup our VMs. Had a few bugs, nothing terrible, probably worked them out by now. Config was very simple and efficient. VDR has dedup and incremental backups; I'm not familiar with Veeam Backup's features

    Good luck!

        VDR is horrendous. If you've ever used the product you wouldnt waste your time with it. Its very new and VMware have a long way to go with it before it can be become a robust and stable enough solution for backups.
        Depending on the size of your enviroment Veeam do a free backup solution that includes FastSCP. Also VM Explorer by Trilead is also a very good backup program with a free and also paid for version.

          We used it to backup a couple dozens of VMs without special configurations (not SQL or Exchange). As I said, there were a few bugs, mostly nothing that a VDR restart didn't fix. Had to recreate the backup job from scratch once

          I can tell you this: the team that makes VDR is very committed and whenever I had a problem and opened a case, they were very eager to help.

          I guess that in the end I agree - wouldn't recommend this a primary backup solution, too many glitches and no support for transactional DBs.
