Using veeam B&R to shrink a virtual disk

Veeam Logoby marius roma » Thu Oct 19, 2017 8:51 am

A Windows Server 2016 VM was configured with a single large thin virtual disk (vmdk) of 500 GB
The Windows partition inside the virtual disk was resized to 100 GB and now the virtual disk contains the Windows partition and 400 GB of unused space.
However, the space used by the virtual disk in the VMware datastore remains 500 GB and I don't see any option in VMware ESXi or VMware vShpere 5.5 to reduce it.
Can I use Veeam B&R to backup the VM and restore it reducing the space used by the virtual disk in the VMware datastore to 100 GB?
As the VM is quite critical, can I ensure that the restored VM will be identical (same SID and same configuration) as the VM backed up and that I will be able to power it on and use it without problems?
Is there any additional issue I should consider?
Regards

Hi Mario,

You cannot do that with the Veeam B&R functionality.
However, there is a workaround by VMware that can help you to achieve what you're after.
Please review this post for the instructions. Thanks!
