Every Company or organization, mostly have file server to store company data, same to my company. We have a file server which store all the important file and the file server has actually MAP to every employee’s PC when the login to windows. The purpose of mapping this drive is to let them share the data with all the department.
As an IT Officer in this company, I am responsible to ensure the backup of the data has successful everyday. My Company are using “HP DLV IV data cartridge”(Picture Above) which is a backup tape that has 80GB storage space.
Back to 5 year ago, according to the record in my company and the old server backup device which is still exist now, they are using “HP dds-3 data cartridge”(picture above) which is only 24GB storage space. I have found out the device in IT store room and some of the tape as well, and also once of our Email server also attach with it device, but no longer use any more.
