So it sounds like you are trying to do a cold backup (cold backup = backup via the recovery disk when the operating system is not running). Correct?
This is one thing that you cannot do in trial mode.
Is there any reason why you are not doing a 'hot' backup (with operating system running)?
With System Recovery, there are two ways of backing up a machine:
As you are in trial mode, you should probably do hot backups as cold backups require a license key (you would need to contact your local Symantec sales team to see if they can provide you with a temp key if you really want to test this feature).
Hope that helps.
You can get everything you need from the trialware site:
You need to download the product itself - you obviously already have the recovery disk.
With Ghost no longer available, I figured System Recovery 2013 is the product I should be considering. Do I have that wrong? Testing the cold backup capability is important, and the prompt for a license key makes testing impossible.
No, you don't have that wrong. SSR is the migration path for Ghost customers.
If you need a license key to test the cold backup feature, I would recommend that you contact your local Symantec sales office for assistance.
