Tip

There will be times when users will want to schedule daily/hourly incremental backups of certain tables/ databases. This is possible within the existing GUI. For example users want to schedule an incremental backup every two hours during the working hours and one full backup at 12 midnight. Specify 9 Incremental backup schedules every two hours apart starting from 6 A.M. and going upto 10 P.M. Specify a Full backup at 12 P.M. Modify this example to suit your requirements.

Backup Time

Fig. 8 Backup Time

• Backup Time input box (No. 4 above) allow users to specify the time of day when the backup run starts.
• ZMC follows a twenty four clock with mid-night being 00:00 hours and 1 P.M. in afternoon being 13:00 hours.
• Hours can be integer values between 0 to 23 while minutes can be integer values between 0 to 59.
• This time is the same for all days/dates within a schedule.
• To specify different start time for different days/dates, make separate schedules for the same Backup Set.

Add Schedule Button

Fig. 9 Buttons

• When no schedule exists for a Backup Set, only the Add schedule Button(No. 6 above) is visible.
• The Add Schedule Button (No. 6 above) allows users to save the schedule specified to the existing schedules as an additional schedule.
• ZMC does not check if there is any overlap between the existing schedule and the new schedule that is being saved. Therefore it is possible to specify in two schedules that Full Backup should take place on Monday nights at 12 P.M.
• In practice ZMC will run just one Full Backup at that time.
• ZMC does check that two identical schedules cannot be saved. It responds with a message in the message window that'Specified entry exists in the list of scheduled entries. Not adding it again.'

Modify Button

• The Modify Button (No. 7 above) allows users to save the modifications to an existing schedule.
• While saving, ZMC does not check, if in fact, users have made any modifications or not to the existing schedule.
• It simply saves the parameters that are specified in the GUI and responds with a message in the message window that 'Scheduling parameters have been updated for this backup set.'
• ZMC does check for correctness of the parameters will point out errors in the message window.

Delete Button

• The Delete Button (No. 8 above) allows users to delete any existing schedule.
• There is no undo button so users should exercise care before clicking the button.
• There is no restriction on creating a fresh schedule that is identical to a deleted schedule.
