They maintain a database to remember which tape contains which piece of data
and from that they automate picking the right tape. They also offer other
functionality like integration with databases like SQL, Oracle, DB2,
Exchange, with NAS devices like NetApp Filers to run NDMP, with open file
managers, with SAN devices etc.

The basics of a backup package are not that hard. You pay for the advanced
functionality that make your life easy. Backup is an insurance policy. If
you pay the lowest fee possible, expect to have difficulty collecting when
disaster strikes.

Have you looked at Amanda for backup? Integrates with mtx and can handle
both Unix and Windows clients. http://www.amanda.org/
