 - an additional copy of the data
 - to a different media type (tape)
 - to an additional location (you can move tape offsite)
 
-Tape backups do not provide random access to the stored

+Statistics show that 95% of all restore jobs restores the last
+backup. Restore requests further declines the older the data gets.
+Considering that, tape backup may also help to reduce disk usage,
