 A later version of tape backup for the Corvus Omninet was called "The Bank" and was a standalone Omninet connected device that used custom backup tape media that were very similar in shape and size to today's DLT tapes.Both the Corvus File Server and The Bank tape backup units were in white plastic housings roughly the size of two stacked reams of paper.In 1980 Corvus came out with the first commercially successful local area network (LAN), called Omninet.
