About predicting disk usage in the Storage
Provisioning Option
After you install the Storage Provisioning Option, Backup Exec can predict the
usage of disk space on the storage arrays. You can configure Backup Exec to send
an alert when it predicts the amount of available disk space for all storage arrays
is low. The alert provides information about whether the current disk space
resources are sufficient, and can help you plan when to increase disk space.
Backup Exec gathers sample data for statistical analysis. For example, you can
use the defaults to let Backup Exec gather data for a one-week period of 24-hour
days. To ensure statistical accuracy, by default Backup Exec keeps 35 sample
groups of data. Backup Exec examines the job history data for each sample group
and uses the new data to recalculate the disk usage trends.
