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.
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.
