As stated by the authors themselves this is the first study aiming to investigate whether there is an added effect of
adding tape to MWMs in painful shoulders, and consequently care must be taken not to overinterpret the results.
As the number of servers attached to the network increases, so do acquisition costs for
adding tape drives, manpower requirements for performing daily or weekly backups, and traffic on the LAN.
Since tape mechanisms do not affect correctness,
adding tape calls cannot break any application that has already been debugged.
Adding tape libraries to a SAN allows users to address backup issues in a variety of ways.
As the amount of data grows ever larger,
adding tape drives and sequential autoloaders to handle the backup merely makes the process longer.
