Veeam vs Doubletake

Hello experts.

After reading some past EE answers Veeam is the better choice compared to Acronis.

San -San realtime replication is going to be too expensive.

However the company wants to replicate to a other place.

In doubletake i know you can set parameters so it wil replicate every 256MB or what ever
the size is set to. I cannot find this in Veeam. Will it shorten the replication cycle?

I'm not incredibly knowledgable on VEEAM as that's someone else's project in our company. I can talk about DT though. Unless VEEAM just does not do what you need it to do, and I think that it does, stay away from DT. DT does what it claims it will do. From many aspects it's a fine product. But we found that it was a resource hog, especially on the remote server that was being backed up. On some of our more heavily used servers we had to turn it off at certain times of the day because it was interfering with the processing that was supposed to be happening on that server. Second, it seemed that we were constantly tweaking the thing and the thought that ran through my mind at the time was "If this change is so critical and really helps, why isn't it in the SOP for the installation?". And there were no downsides I could see for most of the changes that I made. We finally abandoned it in favor of VEEAM and in concert with a product called Could Array and some S3 cloud space we now have local backup as well as something approaching a reasonable DR strategy. As I said at the beginning though, I am not well versed on this last part as it's someone else's project.

Veeam replicates the Entire VM for DR.

Replication time is based on the amount of changes in the VM, over a period of time, or between replication cycles, and how busy that server is.

Which Double-Take product are you referring to?

It's a faster better solution, but its' comparable with VMware HA or FT.

But it's a very different product to Veeam Backup and Replication.

What requirements do you have?

The products offer to different types of Recovery Point Objectives/Recovery Time Objectives

Doubletake is typicall used for real time failover, where the destination server takes the personality of the downed server and allows users to stay up and running.  The Recovery Time Objective is very low since the system takes over from your current one but does require double of licensing/hardware/etc.

Veeam is more of a backup and replication product that offers disaster recovery versus business continuity in that the systems/VMs are warm/cold versus hot with doubletake.


You will need to define your RPO/RTO and find a solution that fits.  On another note VMware now offers vSphere replication bundled in with most of their versions (standard and enterprise) starting in 5.1.

That's a question I should have asked as well.  I was speaking about the DT backup product...

We aborted replication all together, as the times wanted are not possible for the amount of money they want to spend on it.
