Symptoms

ddb.deletable = "false" flags inserted by the backup engine are not removed from the virtual machine's descriptor file(s) (vm-name.vmdk, vm-name-00000x-delta.vmdk files)

Snapshots are left behind when the engine tries to delete the snapshot after the backup is complete

The problem is only noticed on ESX Virtual Machines upgraded from ESX 3.5 to vSphere installs

Purpose

This article provides steps to delete the snapshots left behind by VMware Data Recovery.

Resolution

This issue is addressed in VMware Data Recovery 1.0.1, but you must run the script attached to this article or manually edit the virtual machine's descriptor files to clean up the snapshots left behind by VMware Data Recovery 1.0.0.

VMware recommends following these steps prior to upgrading your environment to newer versions of VMware Data Recovery.

To resolve this issue:

Copy the attached fixdeletable.py to the ESX|ESXi host's vmfs volume with the affected volumes.

Log in to the ESX or ESXi host and run the command provided for your host:

For ESX Server: # /usr/bin/python fixdeletable.py

For ESXi Server: # /bin/python fixdeletable.py

The output appears similar to:

[root@server]# python fixdeletable.py
Checking disk ./win2k3-thick/win2k3-thick.vmdk: NOT AFFECTED
Checking disk ./8gbDC/8gbDC.vmdk: NOT AFFECTED
Checking disk ./win2k3-thin/win2k3-thin.vmdk: NOT AFFECTED
Checking disk ./xpsp2-temp/xpsp2-temp.vmdk: NOT AFFECTED
Checking disk ./2k3_test/2k3_test.vmdk: NOT AFFECTED
Checking disk ./folder/win2k3-template8gb/win2k3-template8gb.vmdk: NOT AFFECTED
Checking disk ./milkyFT/milkyFT.vmdk: NOT AFFECTED
Checking disk ./test_2k3/test_2k3.vmdk: FIXED
Checking disk ./Win2k8/Win2k8.vmdk: NOT AFFECTED

Where FIXED means the VMDK disk had the descriptor issue which the script has fixed, NOT AFFECTED means there is no issue with that descriptor

Repeat Step 2 on all affected vmfs volumes.

Open vSphere Client to the ESX or ESXi host or vCenter server managing the ESX|ESXi host.

Choose the Hosts and Clusters view and choose the virtual machine affected.

Create a Snapshot using the Snapshot Manager for the virtual machine

When the Snapshot is complete, click Delete All to remove all snapshots for the virtual machine.

Repeat steps 5-7 for all virtual machines affected.

Note: This issue may also occur with other 3rd party backup software.
