backup failures & this one is mentioned:
"...
■ If the VMware backup host cannot access the VMware datastore by means of the transfer type that was selected for the job, the backup fails.
Select a different transfer type and retry the backup.
The final status code for the failure depends on whether the backup uses VCB or vStorage, as follows.
■ For VCB backups: The backup fails with status 156 and the bpfis log on the backup host may contain messages such as the following:
12:23:29.998 [3892.3332] <2> onlfi_vfms_logf: [2008-05-07

-00001a1a24e4/1 found.
■ For vStorage backups: The backup fails with status 6 and the job detailed status log on the backup host may contain messages such as the following:
12/4/2009 1:12:34 PM - Error bpbrm(pid=21376) from
client moneevm4_clone:
ERR - Error opening the snapshot
disks using given transport mode: Status 23.
12/4/2009 1:12:39 PM - Error bpbrm(pid=21376) could not
send server status message
12/4/2009 1:12:40 PM - end writing; write time: 00:00:28
the backup failed to back up the requested files(6)
..."
So the suggestion is to try a different transfer type.
Also from the
VM Admin Guide
"...
The transfer types determine how the snapshot data is sent from the VMware datastore to the VMware backup host. The appropriate option depends in part on the type of network that connects the VMware datastore to the VMware backup host.
