## Usage Guidelines

This command determines how often automatic system backups will be performed.&#x20;

The system aligns the start time for the backup process relative to midnight on the day the command is issued or the system reloaded. For example, if the interval is set to 8 hours, backups will occur daily at 12 AM, 8 AM, and 4 PM every day. If the interval is set to 18 hours, backups will occur at 12 AM and 6 PM on the first day, and 12 PM and 6 AM on the second day, then repeat.
