Hello,<br />
<br />
We have a xenserver 6.0 environment with an iscsi SR that has had an RAID problem, disk replaced, and now VMs with Windows 2008 R2 have strange errors. Probably because the underlying SR has bad blocks. <br />
Most of the VMs run fine, perhaps the parts of the windows file system that has been affected is not used in the VM - we are lucky.<br />
<br />
So, we try to use a VM backup software to pull the VMs and store them elsewhere, but the snapshot hangs on 56 % probably cause it reaches something bad on the drive. Is there anyway to get these VMs snapped and extracted? <br />
<br />
Any ideas? We´ve seen the Acronis software can do this, but is it less sensitive to these errors.<br />
<br />
Thanks <br />

Backup virtual machines with bad sectors

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
