to avoid this you can either use option number 3 (export domain) or use a template and copy the disks to several different Storage Domains > > I just wanted to have a external backup. If you can use an external backup to backup only your Storage Domains on the storage server, then you can use the Import Storage Domain feature more safely, since if, at any time, your Storage Domain will be ruined, you can create a new setup and import it the backed-up Storage Domain. > > > Regards > Hemanth > > Thanks & Regards > Hemanth Nalluri > +91 973 999 3635 > > On Thu, Apr 30, 2015 at 9:05 AM, Maor Lipchuk <[email protected]> wrote: > > > Hi Hemanth, > > > > What is the purpose you want to backup your VM? > > Today, there are several ways you can backup a VM: > > > > 1.
