3 Change the following defaults as appropriate:
Type the number of days before low disk
space occurs that you want Backup Exec
to send an alert.
The default number is 30 days.
Send low disk space alert x days before
predicted low disk space condition for all
storage arrays
Type the number of sample groups for
Backup Exec to average to ensure a valid
analysis.
The default number is 35 sample groups.
Sample groups
Type the number of samples per group.
Each sample is a period of time during
which Backup Exec gathers data. For
example, if you specify the default of
seven samples per group, Backup Exec
gathers data for seven periods of time.
The period of time is the sample interval
that you specify. Backup Exec averages
the samples in the group for statistical
analysis.
The default number is seven samples per
group.
Samples per group
Type the number of hours during which
Backup Exec gathers data for a sample.
For example, if you specify the default
sample interval of 24 hours, Backup Exec
