Consider the following points when setting up an alternate location for disaster recovery information:
Although you can set up an alternate location for disaster recovery information on the local backup server and replicate this information locally, we recommend that you use a remote machine.
Although this is not recommended, when specifying the shared folder name in the Disaster Recovery Wizard, you can use a shared drive and any folder or subfolder on that drive to specify that disaster recovery information is to be replicated to that folder. If you must do so, ensure that the folder itself and all parent folders, including the shared drive, have proper security and permission settings for the user account being used.
Connection to the remote shared folder is established using Windows network services. This is fully supported by Microsoft but the service itself has a limitation. If a connection already exists to the remote machine hosting the shared folder, the wizard cannot verify and use the user account information you provide. The replicating operation relies on the existing connection and the credential supplied there.
