You have a long save window, which means that you have an 8- to 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).
| 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 capacity.
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 |
