  • Questions about agent-less backup


    I am trying to decide if I should go with agent or agent-less and I've run into several questions that my searching has not been able to answer so I thought I would post here and see if I could get the info all in one place.

    Environment is vmware with 8 vm's, a combination of Active Directory and Exchange servers on Win 2008 R2 and 2012 R2 running on esxi 5.5 free.

    The goal is to use continuous virtual standby hourly. In the event of hardware failure the standby can be turned on with the loss of only an hour. As well the standby can be copied offsite for DR.

    First question is about licensing. From what I've read I can backup all 8 vm's with 1 license if I use agent-less. If I choose to install the agent on each machine will it recognize this is a single vmware server and need just one license or do I have to pay for all eight licenses?

    This machine is running esxi 5.5 and is the free version. Will we need to buy (at least) essentials for rapid recovery to back it up agent-less?

    The main purpose of protecting this machine is to do continuous virtual standby for the AD and Exchange servers. I have read that agent-less backup does not read Exchange/SQL meta data. So does that mean I won't be able to do continuous virtual standby or just that I could not use these backups to restore individual databases, mailboxes, email items etc?

    These are very small Exchange servers (maybe 15 users each) so hourly backups with continuous virtual standby is a ridiculously easy and cheap way to completely restore these machines in minutes back to an hour ago. If I can do this with agent-less for one license that would be amazing. I can even take copies of them offsite for DR.

    Ideally having the ability to restore mail items, databases would be great too but I can live without that in this case. But speaking of that, if the client is running some other agent on the guest's (for exchange item restores) would that affect rapid recovery in any way? I'm thinking it would not.

    Any help with these questions is greatly appreciated

    Please help...

    I didn't find the right solution from the Internet.
