Plans for future growth of the amount of data
ABC plans to grow at 15 to 20% per year. The amount of data to be backed up
is expected to grow accordingly. This has implications not only on the amount of
time it takes to run backups and backup devices needed for backup, but also on
the size of the IDB.

• How often data needs to be backed up
Full backups of each type of data are carried out once a week on Fridays,
Saturdays, or Sundays. Level one incremental backups are carried out daily on
week days. However, if a full backup is carried out on Friday, then the
corresponding level one incremental backups are carried out on weekdays and
then on Saturday, skipping Friday.
Proposed solution
Because of the issues presented by the current backup solution, described in Problems
with current solution on page 315, ABC is undertaking a project to redesign its data
storage system.
Solution overview
Each of the three departments at ABC Cape Town must be configured into a
Manager-of-Managers (MoM) cell. Additionally, both ABC Durban and ABC Pretoria
should be configured into MoM cells, each with two Data Protector cells.
