VCB backups

[Gee, Norman]

After an update of the ESX server software, my VCB files backups has
started failing.  My VMware administrator want me to changed the VCB
mount command from -a ipaddr:server to -a name:server.  This command is
automatically issue from the TSM client and I don't see how I can change
it.
 
Is there other ways of files backup in a VMware environment?
I can change the image backups, since I execute my own scripts.
