HP B6960-96035 - Manual (Page 309)

Table 18 on page 309 shows the size and time requirements for these full
backups as of today, as well as the five year projection.

Based on the assumption that the estimated size of an incremental backup is
5% of that of a full backup, a full backup of all data that is remotely backed
up in the largest department, the English Department, as well as incremental
backups of the other two departments is projected in five years to take
7+5%(7+3) hours, which is less than 8 hours. This is well within the allowed
12 hours.
• Media Pools
Media are grouped into media pools to provide better media tracking and control.
Group each of the two media types (DLT and DDS) in its own pool.
• Default DDS
This pool should be used for all DDS media.
• Default DLT
This pool should be used for all DLT media.
• DB_Pool
This pool should be used for the IDB and configuration files. The database
should be backed up to two media for security reasons.
• Backup Specifications
Configure five backup specifications, one for each department, and one for the
IDB and configuration files:
• ENG1_BS
Backup specification for the Windows 2000 client to be backed up locally
in the English Department. Schedule the backup specification such that Data
Protector will run a full backup every Friday and a level 1 incremental backup
every day, except Friday and Sunday at 20:00.
