  • Vmware Backup

    hi,

    Am new to virtualization..... Please tell me about vmware backup terminology like if ESX server is booting from SAN and all over file server data and exchange database in on SAN.......so how we will take backup of individual database means exchange database or file server backup.

    More specific still we use windows backup utility or a new software will be installed on each virtual machine than we will take backup.


    Thanks

    That will completely depend on your setup. You can continue to backup with an agent in each VM, or you utilize the tools (some of them 3rd party) that enable you to backup the whole machine (as an image) or the files in the VM.

    If you doing this from a SAN then you backup server (option 2 from above) will have to be connected to the same fabric.

      VMs are usually backed up internally, on their OS level.

        Beg to differ, that depends on your infr.

        We changed from an agent in each VM to snapshot backup on central storage.

        1. better administration
        2. better service to the clients
        3. saved $300 per agent per VM

          don?t snapshots take up much more space on the storage?

            Re: Vmware Backup

            We are not talking about ESX snapshots but Storage snapshots.

            NetApp and EMC each have their own way to deal with that

            And we can live with the amount of storage it takes...

              yeah, the SAN snapshots are a nice feature

              but how about remotely stored media? for real disaster recovery

                Simply put,

                =snapshots are for disaster recovery purposes for restoring the entire virtual disk(s) from a snapshot in time. These typically take up a lot of disk storage so I would only recommend using snapshots for the OS drive.

                =agent based backups are for daily restore tasks on a file by file level. Typically use agent based backups on the data drive(s).

                Using a combination of both of the above technologies is commonly called "the one-two punch" backup strategy.
