You should save everything in your system as often as possible.
You might not be prepared to recover from a site loss or certain types of disk failures if you do not regularly save everything. If you save the right parts of your iSeries™ server, then you can recover to point 4 (the last save) shown in the backup and recovery timeline. You should save the parts of your system that change often daily. Every week, you should save the parts of your system that do not change often.
This table shows the parts of the system that change often, and so should be saved daily.
