About initial backup
The first backup will take the most time, since all files selected must be backed up. If the customer requires backup of a large capacity, an initial backup may be the fastest solution. This feature allows your customer to backup to a local buffer on the DS-Client computer, or to any other buffer location at LAN speed. Then, they will ship that media (disks) to the DS-System’s physical location.
When you receive the initial backup media, you will import the data to the DS-System. Once it is imported to the DS-System, your customer can continue performing scheduled and on-demand backups (of incremental changes).
NOTE:  The initial backup service is not a software-only process. It must be coordinated with the DS-Client administrator.
