The Power Edition server, like the Backup server, schedules backup of data and
automates the process so that you do not have to change media or start the backup
procedure manually. You can create schedules that back up your data at times when
it is least used, for instance, at night or on weekends.
The Power Edition server also maintains records of the data backed up by the Power
Edition server and its storage nodes, to make recover operations easier. In client file
indexes, the server records the filename of each piece of data. In the media database,
the server records the contents of each media volume. Browse policiesand retention
policies determine how long these records are kept. Backups you make on a Power
Edition server or storage node can be read by a Backup server, and vice versa.
Power Edition also supports the file device type, for backup to disk, and save set
staging, which enables automated transfer of data from one medium to another
according to policies you define.
Because these functions are the same for Power Edition as for the Backup base
product, refer to your platform's Solstice Backup 5.1 Administration Guidefor more
information about the scheduling, media management, and index management
features of the Backup product line.

Performance is the speed and efficiency with which a task is completed. Backup and
recover performance is dependent on several hardware and software variables, but
in general, your backup can go no faster than the speed of your slowest component.
This guide provides tests you can use to measure and maximize the performance of
your computer. When you find the slowest component in the data path between the
location of the data and the storage device, you can change software settings or
replace a hardware component to improve backup and recover performance.
Hardware performance is limited by the lowest data rate of the following computer
components and related performance factors:
*Server speed
-CPU
-Memory
-I/O bandwidth
-SCSI bandwidth
-Number of ports
