Simple save strategy

You have a long save window, which means that you have an 8-hour to a 12-hour block of time available daily with no system activity (including batch work). The simplest save strategy is to save everything every night or during off-shift hours.

You can use option 21 (Entire system) from the Save menu to do this. You can schedule option 21 to run without an operator (unattended) beginning at a certain time.

You can also use this method to save your entire system after you upgrade to a new release or apply program temporary fixes (PTFs).

You might find that you do not have enough time or enough tape unit capability to run option 21 without an operator. You can still employ a simple strategy:

Daily	Save everything that changes often.
Weekly	Save the things that do not change often.

Option 23 (All user data) on the Save menu saves the things that change regularly. Option 23 can be scheduled to run unattended. To run unattended, you must have enough online backup media capacities.

If your system has a long period of inactivity on the weekend, your save strategy might look like this:

Friday night	Save menu option 21
Monday night	Save menu option 23
Tuesday night	Save menu option 23
Wednesday night	Save menu option 23
Thursday night	Save menu option 23
Friday night	Save menu option 21
