Backup routines above SAN are also much more successful as compared to server by server backup.
Ahead of deciding to move all information into a SAN, it is advised to verify the enterprise applications have the ability to assist SAN. There are a few programs which need their data to be locally stored and might pose a problem when seeking to implement SAN.
