    Neverfail, Doubletake, Symantec System Recovery

    Does anyone have any of these? How is it working out? Does anyone know of an open source alternative to allow me to have virtual backups/copies of the physical servers?

    You want to back the whole thing up? OS and all?

    Is this worth it, just thinking, if the motherboard + hdd dies, = new pc, can you restore onto new hardware. Or you just want to backup user docs etc?

    More along the line of running the backup on virtual machine until I can either fix the original or replace and rebuild it.

    Have you had a look at VMware Converter - Download VMware Converter (Starter Edition) - VMware. I've used it several times to take backups of servers that are being decommisioned.

    I've always used Xen for virtual servers, then just done a "tar dump" of the image.

    I suppose you could just stop the domU copy the virtual hdd, then start it backup. I guess each virtual method would have a way of doing this live.

    TonyD sounds like a good idea. Cheers for that.

    Well I was looking originally at System Recovery and thought it would be useful to have the actual servers backed up in an up-to-date image then if the physical server dies within a few minutes the virtual system could come online. Later on I could just move to the virtual environment all the time. Is this possible with VMware or Virtual Server? Can an image working on a specific piece of hardware work when on another?

    ADS, DC half the master roles and some specialist software. Got another 4 servers with similarly important roles that could do with a backup.

    Note: vds = virtual server | dedi = physical servers

    Could setup the master AD as the dedi server, then the vds as the backup.

    Otherwise your talking clusters\load balancers\

    I know openbsd has carp, which is free, which can do fail overs. This is a big can of worms tho.

    If the stuff doesn't support mutliple servers\clusters\load balancing whatever you want to call it, use VM converter to copy the server, or create a manual copy, onto the vds, then manually start the vds when the dedi failes. Perhaps looking at Nagios to alert you when\if the real server failes.

    Does that help? Point you in the right direction? Confuss you?

    You will want to have a look at PlateSpin's power convert. PlateSpin Products - PowerConvert

    In addition to the ones you mentioned, another option include SteelEye's Windows Protection Suite and their Citrix XenServer Protection Suite.

    FYI...XenServer is much better than VMware Server or MS Virtual Server 2005. I'd look at VMware 3i, MS Hyper-V or Citrix Xen Server as your Hypervisor.

    Now I just need to find a price on all of these

    What features make XenServer better than VMware and MS Virtual Server?

    Look at #9, #10 and #11 in the FAQ. Citrix XenServer is a type-1 Hypervisor as described in the FAQ.

    In general, the performance and management capabilities are much better in a type-1 hypervisor. Cost is becoming less of a factor as all of the major players have a "free" low-end type-1 hypervisors.

    - VMware 3i
    - Microsoft Hyper-V Server
    - Citrix XenServer Express
