This post lists all the Configuration Manager maintenance tasks and details of each task. At each site, we have predefined set of SCCM maintenance tasks available and we will explore these in detail.
Configuration Manager comes with set of 49 predefined maintenance tasks. We do see new maintenance tasks added by Microsoft in current branch updates. For example with Configuration Manager 2010, a new maintenance task was added called Delete Aged Collected Diagnostic Files. This task lets you clean up collected diagnostic files.
There are approx. 49 Configuration Manager maintenance tasks and each of them serves a purpose. In coming years, we may see more tasks added. Some of these tasks are enabled by default when you install Configuration Manager. While the other maintenance tasks needs to enabled by admins if required. Please read the maintenance task description and then enable the task.
What are Configuration Manager Maintenance Tasks
Configuration Manager Maintenance Tasks are the tasks designed to keep your Configuration Manager site healthy. Once you install Configuration Manager, regular maintenance is important in order to keep site operations running correctly. You don’t have worry because when you install Configuration Manager, it comes installed with built-in Maintenance tasks.
You can enable, disable or edit a maintenance task. Although you may disable the maintenance task, they are super useful and very important for maintaining the overall health of Configuration Manager.
Types of Configuration Manager Maintenance Tasks
Configuration Manager Maintenance tasks can be classified into three categories based on how often you run these tasks. Some tasks require to be run on daily basis while the others can be scheduled to run on specific day and time.
There are three types of Configuration Manager Maintenance tasks and I am quoting as per the information from Microsoft documentation.
- Daily Maintenance Tasks
- Weekly Maintenance Tasks
- Periodic Maintenance Tasks
Daily Configuration Manager Maintenance tasks are some of the common tasks that you should consider to run on a day to day basis. Some of the common daily maintenance tasks include Configuration Manager alerts, checking the Configuration Manager database status etc. Most of these tasks are enabled when you install Configuration Manager.
Weekly Configuration Manager Maintenance tasks are supposed to run on a weekly schedule. Examples include check available disk space on all site systems, check the site database size, delete unnecessary files from site systems.
Periodic Configuration Manager Maintenance tasks are important when it comes to ensuring the good overall site health. These tasks are not required to run on daily or weekly basis. Rather these tasks are related to overall site.
