5.1.3 Backup File Retention Period Setup

When backup files are continuously saved in a computer, the hard disk soon fills up and is no
longer able to save backup files. As such, you should either delete old backup files from the
backup computer on a regular basis or manually move them to another storage media such as
tape or optical disc.
To manage backup files effectively, choose a retention date/period for backup files to delete
them automatically when they 'expire'.
To set a retention date, click the numeric spin buttons under [Retention Period] and adjust the
value. The period can be from 1 day to 365 days with a default value of 5 days.
When the retention period expires, backup files are automatically deleted from the backup
computer. Three different checkpoints for the retention period are provided: first is when the
[Apply] button is clicked after a backup operation is scheduled, and second is when the backup
program starts operating. In these two cases, the backup program counts 24 hours from the
checkpoints to determine the retention period. Last is when a message window appears alerting
that there is insufficient backup space in the hard disk.
In this case, a message window appears prompting you to delete backup files if they have
expired. Clicking OK deletes the expired backup files.
The backup retention period starts counting based on the recording date of the
first frame.

5.1.4 Backup Drive Setup

Select a drive to backup video files. For a hard disk with multiple partitions or a computer with
multiple hard drives, you can choose which drive to use for backups.
