Automated Nexus 5500 Backups

Automated Nexus 5500 Backups

When I attempt to perform a backup of my Nexus 5596 switches, they fail with the following error:
 
copy startup-config tftp://10.10.10.21/1805_ConfigFile.txt vrf default
^
% Invalid command at '^' marker.
Nexus-5596# copy startup-config tftp://10.10.10.21/1805_ConfigFile.txt vrf default
Trying to connect to tftp server......
TFTP put operation failed:No route to host 
Nexus-5596#





 
The reason it is failing is because the automated backup uses the default vrf. However, the Nexus has out of band management interfaces that have been configured on my switch for management tasks, such as this. I need to be able to specify the management vrf.
 
How can I specify the management vrf for automated Nexus backups?
Do I need to create a custom template?
If I create a custom template will I still get the benefits of the automated backup (storage of configs in the db, exporting of configs to folders, compliance checking of configs, comparison of running/startup configs)?
