BackupPC: How do I run hourly incr backups?

[rozilla]

# Minimum period in days between incremental backups (a user requested
# incremental backup will be done anytime on demand).
#
# Typically this is set slightly less than an integer number of days. The
# time taken for the backup, plus the granularity of $Conf{WakeupSchedule}
# will make the actual backup interval a bit longer.
#
#$Conf{IncrPeriod} = 0.97;

$Conf{IncrPeriod} = 0.1;

I tried setting it to 0.1, but that doesn't seem to be working. How do I run hourly incremental backups? Or every two hours?

It's working now. There was nothing wrong with the above setting, the error came from elsewhere.
I love BackupPC, but it can be a pain in the ass to configure! :D
