VMware_VDDK: One of the parameters was invalid

Thread needs solution

Hi everyone,

I am getting this error on two different sites when backing up a particular VM.
This VM at both sites is Openfiler 2.99 with vmware tools installed.
The backups validate fine, the RAID5 is not degraded and the load on the servers is fine.
The amount of data that is being backed up is about 300GB which resides on a 900GB vHDD
Im running vmProtect 7 as a windows agent and running ESXi 5.
Im using CBT for the backups.

Any help on these would be great.

Hello David,

Thank you for reporting about the issue.

We need to find out what exactly causes this error, as the above log doesn't shed the light onto the situation. Please enable debug logs: 

1) On the machine where vmProtect Agent installed (Windows one) go to Start->Run->regedit and browse the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\Global\Configuration\
Modify the DWORD "DebugTrace" value and set it to "1"
2) Restart Acronis vmProtect Managed Machine Service (from Start->Run->services.msc)
3) Reproduce the issue once again
4) In Acronis vmProtect web console go to View->Show Logs->switch to dynamic (orange) Logs tab->click Save All To File button to save all the logs which will contain the additional debug information.
5) Please send me these logs so that we can analyze it.

Should you need anything else or have any further questions - feel free to contact us at your earliest convenience, we will be happy to help you!

Thank you.

Hello David,

Thank you for your patience. We've got some news from the Development team: 

We have a pre-released build where the issue is no longer reproduced, so I'm currently uploading it to the FTP account I've created for you, and will send you the link to it in a minute.

Please install the update, and let us know whether the issue is still present.

Let me know if you have any additional questions, we will help.

Thank you.

Hello David,

I wanted to follow-up with you and we were wondering if you were able to install the build that Yana sent you via ftp and if you are still having this issue.

Looking forward to your reply and if you have additional questions please let me know.

Thank you.
