Consider the following when working with the Storage Intervals page:
Before you can change storage interval settings, CMS must be in single-user mode and data collection must be disabled.
Perform a full backup of historical data before changing the intrahour interval or data summarizing time settings. After making the changes, perform another backup.
Free space allocation, data storage allocation, and storage intervals are closely related. When you change storage interval settings, you might also need to adjust the values on the Data Storage Allocation page. The more frequently CMS archives data, the more storage space is required. Keep this in mind before changing the frequency of the intrahour interval.
Changing the intrahour interval can result in a lengthy process as CMS must make modifications to all previously-collected data.
In the PC Client, do not open another Storage Intervals window if one is already being used to modify settings. Loss of data tables can result if multiple Storage Intervals windows are used.
