The emerging storage management standards provide the assurance customers need, and this translates into increased sales opportunities for resellers. In addition, the products themselves are more price-competitive. Standards also shorten the sales cycle. Tapes could not be interchanged because a common tape format didn't exist.

If an organization wanted to change systems, they had to keep the old backup software and hardware in case they needed access to one of their archived tapes. SMS and SIDF Standards SMS is a defacto standard developed by Novell to provide a consistent interface into the network's file system. It ensures that safe, reliable backup, archiving and storage management can be achieved with current and future versions of NetWare. SMS became an industry standard because of the obvious benefits it provides to NetWare users. The API provides backup software suppliers with a consistent mechanism for retrieving data from the server.
