library has two drives and a sustained data transfer rate of 6 MB/s (2 x 3 MB/s),
or 21 GB/h. Therefore, data is backed up to this library in up to 5 hours. The
projected amount of data in five years, 185 GB, would be backed up in 9 to 10
hours, which would still be within the acceptable 12 hours.
Cells D and E at ABC Pretoria share an HP StorageWorks DLT 4115w Library.
This library has a single drive and a sustained data transfer rate of 3 MB/s, or
10.5 GB/h. The total amount of data to be backed up in these cells is
approximately 22 GB. This would be backed up in 2 to 3 hours. The projected
amount of data in five years, 55 GB, would be backed up in 5 to 7 hours, which
would be within the acceptable 12 hours.
Similarly, the 16 GB in cells F and G at ABC Durban would be backed up in up
to 2 hours. The projected amount of data in five years, 40 GB, would be backed
up in about 4 hours, which would be within the acceptable 12 hours.
The largest, 1.3 GB, Data Protector Catalog Database at ABC Pretoria should
be backed up in a few minutes, when no database integrity checking is performed
beforehand. Data Protector by default checks the integrity of the database before
the database is backed up. The check operation takes less than an hour for a
1.3 GB database. Therefore, the IDB and configuration files at ABC Pretoria
should then be backed up in under 2 hours.
• Media Pools
Media are grouped into media pools to provide better media tracking and control.
Media pools facilitate the management of large numbers of media, reducing the
management effort of backup administrators to a minimum. Use the organizational
structure and the systems categories criteria to define the following media pools:
