Our Systems team is implementing Double Take on client machines for live replication to DR servers. Developer's desktops typically have multiple instances of Visual Studio open at all times which generate 4GB of write IO per hour. Even when Visual Studio is idle it appears to generate large spikes of IO every few seconds. Double Take can only replicate about 800MB in that same time period, so it seems to be playing catch up and is pegging one of the CPU cores on the client at 100%. The machine comes to a near full stop, Visual Studio becomes unresponsive as it seems to be competing with Double Take for IO on the same files.

Is there a way to configure Double Take in a way that will make it play nice on a developers machine? Does anyone have any experience or advice on running Double Take on client machines in general? Is there a different solution that might work better for DR? It does not need to necessarily be live replication.

Maybe a better question is: What is the closest competitor for DoubleTake? I am looking to replicate a windows production server in case it fails have a immediate backup. Any idead?

NOTE 1: I forget to add that this server is on the EC2 Amazon Cloud.

NOTE 2: The main situation we have is recreating the configuration settings like IIS, FTP Server, SQL Server, SVN Server.

NOTE 3:

So far I have been giving three options as answers for my original question:

  1. AppAssurance -- After talking to their sales team they do not support Amazon as cloud provider. Basically there is a technical need to be able to reboot from a disk or similar media. So ESX Virtual machine environment will work, but not the EC2.
  2. Acronis -- which works as a backup in ghost style. This will work for other type of scenarios.
  3. Use the Amazon EC2 API -- This option is ideal, but only works if you are developing a cloud application rather than hosting a regular application in a cloud scenario.

This means that I am still looking for the answer. Any other ideas.

I'm tasked with providing fail over of our Exchange 2003 Server. Currently we're using Microsoft backup to backup the mail store nightly over the network to another machine. We currently use double take to mirror a database server and it seems like a reasonable solution for the exchange server but it is quite expensive and I'd need to dedicate a standby server for it. I've heard double take can sync to a VM, but I'm not on support with them anymore and I can't find much info on the subject.

My goals are (of course) to minimize cost and downtime. I'd love to use my double take backup server as a standby for multiple machines (it's got the space), but I don't know if it's possible. The maximum downtime I can afford is less then a day (my servers are on hardware support contracts, but hardware (drives, raid controllers, motherboards etc) still takes time to ship), so I'm not looking for immediate fail over, just the ability to smoothly transition to a backup machine in an emergency.

What have people used? What works well?
