I tried following the process described in this article: http://blogs.technet.com/b/sbs/archive/2009/04/16/how-to-backup-restore-and-re-link-group-policies-in-sbs-2008.aspx

When I followed these steps I had over 50 paragraphs of output similar to this:

GPO: Update Services Client Computers Policy...Succeeded, but note the following issues:

[Warning] The security principal [S-1-5-21-4187703203-3677896876-4144508086-2116] referenced in extension [Core Extension] cannot be resolved, but the task will continue. In the future, you can use a migration table to map or remove this security principal.
Details: No mapping between account names and security IDs was done.
 
What does this really mean and what concerns do I have with so many warnings?

that means that you have in group policy referarls to sid numbers (users ids) which are no logen in active directory - they were deleted- to back up without errors go to given group plicy and remove unresorvable sid numbers.

if you check your log file ( created whilest backing up Gps) you will see unresovable sid numbers and Gps in which are they used.
before you edit given policy (before backing up) you can have a look on settings tab and click show all - this should give you exact place in GP where bad sid is used- then just edit Gp remove wrong sids( you will know which ones from log file) and try backing up again
