Issue



The Backup job for VMware will fail with "The object was not found, or could not be accessed (VMware backup)."


Error



Job Log error:   0xe0001705 - The object was not found, or could not be accessed (VMware backup).

 

Debug of the RAWS shows the following:

[6004] 06/17/11 23:50:33 [fsys\shared]        - VDDK-Log: NfcNetTcpRead: timed out waiting for data

Cause



When running backups via NBD method for the AVVI agent , the VMware Server has a limit to the number of NFC connections allowed.  If this limited is exceeded, it will cause NFC connection timeouts.


Solution



1. Run the Backup job using the SAN method only.

2. Contact VMware to determine what is using all of the NFC connections.
