Stuff we might want to Backup
- OS/400 IBM System Resources
- Application Software
- Libraries
- Data Files
- Spooled Reports
We can save and restore
- Without buying 3rd party stuff
- What comes native with OS/400 support
Save and Restore
- Single object in a library, all its members
- Group of objects by generic name
- Group of objects by generic name and object type
- An entire library
- Only the changed objects in a library
- OS/400 system stuff like user profiles and device configuration
- All libraries other than system stuff
Need 3rd party stuff
- Archive Spool Files
- Archive application files based on some cut-off criteria
Backup Save References
- GO BACKUP
- GO SAVE
- GO TAPE
Restore References
- GO RESTORE
Restore Gotchas
Restore Libraries alphabetically
- Let's suppose you have physical files in one library called GOODSTUFF
- Let's suppose you have logical access to the GOODSTUFF files located in another library called GETGOODIES
- Let's suppose you need to restore several libraries including GOODSTUFF and GETGOODIES
- OS/400 restores libraries in ALPHABETICAL SEQUENCE
- (unless you restoring 100% or
- doing libraries one at a time where you specify which one each time)
- which means it will try to restore GETGOODIES before GOODSTUFF
- but if the physical file that a logical accesses is not on disk at time you try to restore the logical, you will not recover that from the backup
- Lesson or Moral of the story ... if you need to store logicals in a library of different name than that of the physical ... it might be smart to use a name alphabetically after that of the library with the physical.

Managing Performance of what's on Disk
Security Considerations
- Who knows passwords to Master Security?
- such as STRSST System Security Tools
- What happens if that person gets hit by a truck, or other accident removes them from the picture?
- Let's suppose, thanks to human error, the master security signon gets messed up, and no one can sign on with it. What now?
UPS Power Protection
- Do you check Power Protection periodically, so when the battery dies of old age, that is no surprise to you ?
- When it was originally hooked up, was it tested to make sure it was hooked up correctly, so when you need it, because of loss of public utility power, it does protect you?
- If folks do power down / up the same way 99% of the time, do y"all remember how to work the CPU control panel?
