Even when considering maintenance only from a business
point of view, there are a wide variety of possible activities and costs that could be
termed as ???maintenance.???
Consider application patches: at first glance, application of a patch seems like a
technical cost of time required for testing and application. If done properly, though,
application patches require testing time from members of the business unit itself.
They??™re the only ones who have the necessary background to determine if the patch has
fixed existing bugs or created new ones. Unfortunately, thorough testing by the appropriate
business unit is often sacrificed for lack of time.
CHAPTER 5 n CREATING A BACKUP/RECOVERY PLAN 107
An example more applicable to the topic at hand would be the review of an existing
BRP. I??™ve argued previously that disaster recovery planning, including individual backup/
recovery schemes, should not be considered as a project that you need to complete but
rather as an ongoing job role. I??™ve also argued that when creating a backup/recovery
plan, technical staff should never be the ones to establish requirements such as acceptable
data loss, restore time, or service interruption when backing up the system.
