Periodic event administration

There are some tasks that are performed only occasionally on the system. These tasks require thought and advance planning to decrease their impact and maximize the benefit to the organization. Many of the items listed in this area could be considered luxury items, but if you are well positioned in the other aspects of your system, you can invest some time in these tasks to round out the management and maintenance of your system.

Periodic events include:

Annual backups
Archiving
Modifying applications
