In the Backup Preferences for Scheduler are various options for backing up hourly, daily, or on designated days of the week.
This Solution provides instructions for choosing the appropriate settings for the built-in Backup in Big Business Server. (6035)
In the Backup Preferences for Scheduler, there are settings for choosing when, or how often, to back up.
For Backup to run successfully, all Users must close all open windows, or preferably disconnect, to ensure there are no open transactions. In other words, Backup will not work during normal operations; it should be scheduled to run after hours.
The best setting, often, is to have it run each night at midnight (0:00:00) or shortly thereafter (2:00:00) when you don't expect Users will still be connected.
