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.
