If /usr/openv is in the exclude list on a Linux VM (virtual machine) backup host, VMware backups will complete and report success (status code 0) while not backing up any data. The resulting backup image is only 32K (see figure):
No error is reported.
NetBackup mounts the VMware snapshot under /usr/openv/netbackup/online_util/fi_cntl/ which was being excluded due to the entry in the exclude list.
Example exclude list:
# cat /usr/openv/netbackup/exclude_list
The bpbkar log shows:
