XenServer 5.6, DR

Hi everyone.

I have an big issued with Xen-server crashed without backup on VM, the only one I have is the export as backup (snapshot) from the Xenserver for that VM

my question is can I build new xenserver and mount that snapshot from old xenserver to new xenserver just to be able retrieve data from that VM or any solutions for this D.R

many thanks in advance

Yes you should be able to create a new server, install Xen, and mounted the files just like you would be able to on the old server before it crashed.

That is the glory of virtualization, it gives you so many options and standardizes the the virtual hardware across any physical hardware.

Hi Xkincaidx,

that's good new, can you show me how to start this restoration, I already build new xenserver
and the snapshot on usb it about 20GB size
how do I mount that usb onto xenserver? which command?
thanks Xkincaidx

You don't have the GUI accessed through the XenClient? That would make it super easy to be able to mount the USB drive.

Here is a thread that should have everything you need:


I would copy the files off of the USB and into the internal drives first chance you get because we have seen issues with USB drives and reliability.

Hi XKincaidx,

sorry for the confusing, I do have GUI Xen, so when I able see USB on xen, first do I need create new VM disk and install OS back to xen as of original guess running  (fedora) then restore of my snapshot on top or just restore with out create VM first?

thank you for the link, it's very nice good to know

XKincaidx, anything I need to know beside this? many thanks

All you have is the snapshot? You don't have all the files associated with the VM?

Snapshots are used to revert a VM back to a certain point in time, you can't restore the entire VM if all you have is the snapshot.

You might be out of luck.

I though that was my problem at beginning with ( only snapshot ), I just hope any slim chance to recover data from that snapshot?
I might have to call xen support and maybe slim chance they some sort of hope

thanks anyway
