There are two primary situations and respective methods that this KB article documents. Below is a summary of each.
Method A: Same Job, New Backup location
The backup files are being moved to a new repository, but the existing Backup Job will continue to be used. This method will use the automapping function built-in to the software.
Method B: New Job, New Backup location
You are seeding a job or mapping a job to a backup chain in a new location. This method does not require that the job doing the mapping be the same as the job that initially created the restore points, as it requires that you manually use the map backup function.
