Tape is great for long term storage of archival records, but nobody wants to restore a live virtual machine from 7 years ago. Depending on the business system you might want your server to be backed up multiple times a day to just weekly, and if you are doing multiple times a day you do want it to be decently fast or to have some extra capacity so as not to slow down normal operations while the backup runs.
