Storage Management Server - HP BB118BV - StorageWorks Data Protector Express Package User's Manual & Technical Reference

NOTE:
The backup device could have been placed just as easily on any other machine in the network. Data
Protector Express does not require that the backup device be physically attached to a file or application
server. Additionally, while the term "Backup Server" is a convenient label, in fact, Data Protector Express
does not require that this machine have a server operating system. It could just as well be a desktop PC.
This arrangement offers several advantages:
1. Jobs run quickly because most of the data is transferred over local buses, instead of over the
network. In this arrangement, Data Protector Express will automatically route data from each
of the file or application servers over local buses to its own backup device. Whenever there
is a choice, Data Protector Express automatically routes data over local connections rather
than network connections.
2.
Administering jobs is uncomplicated. Jobs can be created and run from any machine on the
network.
NOTE:
Jobs can also be administered from a machine that is a member of a different Data Protector Express
Storage Domain. The Data Protector Express administrator or other user can log on to this catalog from
another Storage Domain and then create and run jobs in that Storage Domain.
3. Suppose a disaster occurs and the RAID device of one of the file or application servers needs to
be replaced. Because the catalog is located on another machine, recovery is quick and easy.
The catalog contains all of the information necessary to restore the lost data. Had the catalog
been stored on the file or application server, recovery would have been much more difficult.
