Setting System Backup Control Maintenance Records

For the system backup program to work, the three following control maintenance records must

be set.

System Backup Administrator

Enter the name of the user or message group, such as BACKUP, to receive the system backup

messages each morning. Use a message group to send the message to more than one person.

System Backup Check Time

Enter the time when the system backup program confirms whether the backup was successful.

The default check time is set to 07:00 a.m., which should allow plenty of time for the backup to

finish.

This check is done every day of the week and cannot be changed. If you do not run a backup on

Saturday and Sunday, a message is sent to the System Backup Administrator that a backup has

not been recorded since the previous Friday. A message is sent for each day of the weekend the

backup does not run. If this time is not specified or if the backup is not successful, the

Administrator receives an error message.

Time can be entered in several ways, including: 9a for 9:00 a.m. or 9p for 9:00 p.m. Military

time does not require an 'a' or a 'p'. When including minutes with either normal or military time,

type a colon between the hour and the minutes. For example, type 04:30.

System Backup Variance %

Enter the allowable percent difference in the amount of backed up data between last night's

backup and the previous night's backup without generating an error message. We suggest that the

variance percent be set to 9 to allow for the normal generation of new data. If the percent

difference between the two backups is greater than the specified number, the System Backup

Administrator receives an error message.
