I often use Windows Azure Virtual Machines to create a test environment. A requirement of such a test environment is to be able to quickly take one or more snapshots of a virtual machine and selectively restore a given snapshot later. Unfortunately Windows Azure (IaaS) does not provide this functionality out of the box.
This is where I use the
CloudXplorer tool.
1. Take a snapshot of the disk (while the VM is stopped)
2. Start the VM, make changes and perform tests. When you have completed the tests, shutdown the VM.
3. Use CloudXplorer to promote the snapshot after breaking the disk lease.
4. Use CloudXplorer to (re)acquire the lease.
You can now restart the VM in the state where the snapshot was taken.

Hello,
thank you for this valuable solution. Have you had any problems with this procedure?
great solution, would we worth automating a bit further into a single dialog
Its important to shutdown the VM via the web interface, so it enters the state "Stopped (Delocated)", else you break the vhd file and leave the VM unreadable.
There may be noticeably a bundle to know about this. I assume you made sure good factors in features also. casino online
