Subject Re: Best way to update Templates
Date Tue, 19 Apr 2016 04:15:22 GMT
Thanks for the reply Kirk.  Will it auto-delete templates if there are not any VMs cloned from
them?  Is there a better way to keep templates up-to-date with patches?

We will be patching these templates fairly often as Microsoft releases new patches.  It sounds
like our secondary storage will grow quite quick if it doesn't delete old templates, or if
we have long-lived VMs that are linked to these old templates.

This does explain why our secondary storage has grown more than we expected lately.

Thanks for any help or guidance you can provide!

Sean

use, it won't actually be deleted on the back-end (i.e. the database entries will remain,
as will the files on secondary storage), rather it is just hidden from the end-users in the
UI and API.  Giving a new template the same name as a deleted one might be a bit confusing
so you could consider adding a version number or date code.
