Hot imaging Linux servers to a virtual environment

Raj Perumal Raj Perumal Profile: Raj Perumal

Hi folks, I wanted to discuss hot imaging of Linux servers. Often you will run into a situation where you need to migrate an existing Linux server into a virtual environment.

The downside is that you might not want to power it down to do this and use something like VConverter or PlateSpin Migrate. These products can hot image Windows servers but can’t hot image Linux servers. So what do you end up doing? Acronis!

Acronis True Image Echo Enterprise Server can hot image a server and then you can use the program to convert the image into a VMDK file which you can then import into an existing virtual machine. Then presto, you have a virtualized Linux server without ever having to down the existing older Linux server.

The only caveat is you have to install an Acronis agent on the Linux server to accomplish this. In order for the agent to install successfully you will require the kernel source to be installed. But then you can install the agent without requiring any reboots.

Happy imaging!
