Hi Kevin,
For the first error, check the permissions for the web user(s) running the application for each site. Refer to the permissions section of the developer's guide:
Disk permissions problemsFor the second error, were there any changes made to the media libraries on the target server, either manually or through the
CMS Desk?
If so, one thing you can try is deleting the media libraries on the target server, both through the CMS Desk and the file system. Then try running the synchronization again.
