Have a look @ this KB -

I cannot view the job log, however the above KB should explain.

I understand that Windows is problem, the KB tells me there is no response.

There are couple of workarounds listed in the KB...In case, you are unable to view the KB, here is a verbatim ~

Disable GRT option for the backup job of the problem virtual machine.


Run a direct backup of the virtual machine using the Remote Agent instead of the AVVI option.

Probe GRT and removing the option did not work,
About make backup files with the option if would be the only way out, I just talked to the specialist VMware, and told me that the 4tb snapshot is not recommended by a lot of space inside the LUNs.

A Symantec systentada solution on this problem ... I can not even make the backup of a virtual machine 4TB ...

How is this virtual machine configured ?
Is the disk on a RDM LUN ?

BTW can you post the exact errormessage, but not in a RAR file ?

And what ESX version are you running on ?

If this response answers your concern, please mark it as a "solution"

1. They are in storage, I have no more details.
2. sending the file as it is and why it compressed nopermite.
3. Esxi version is 5.
Your support, thanks.

Need to have some more info about your storage.

Normaly a VMDK can be 2 TB maximum. Maybe that is the reason something goes wrong.

There may also be issues with 4k sector sizes within the VM (typical of larger drives)

So if vmware can not have a snapshot of 4tb, worse will be able to create the symantec backup, seeing that scenario, what would be the best recommendation???
