Typical IBM i users run system save 21 (full system save) once a week or once a month for DR purposes, which can cause the system to be down for several hours. After switching to Agent Backup, we recommend doing system save 22 (system data only) instead. As, save 22 only saves the OS and license programs, it runs much faster than the save 21. Also, because the Agent saves system state information (security data, configuration data and system values) and can do so while the system is running, one would only need to run the save 22 when ever PTF’s are loaded. Following these recommendations, system down time can be reduced from a couple of hours per week, to maybe one hour every 3 or 6 months, depending when PTF’s are loaded.
The IBM i Agent supports *IBM special value to Backup licensed programs. However, if save 22 is performed to Backup the OS and licensed programs, then it is not needed to create a Job to Backup *IBM since save 22 already includes this.
The IBM i Agent does support *ALLUSR special value to Backup all user libraries. However, because the Agent is not limited to a single device, it is recommended to divide up user libraries into several Jobs to get the best performance. The general recommendations are:
• Create 3 or more Jobs per available cpu.
• In general for *OBJ Jobs try to keep total object count per Job below 10,000. • Create separate Jobs for volatile objects like databases, journals receivers, etc
and for non-volatile objects like programs, service programs etc. (even if they reside in the same library). This is easy to do with the include and exclude features of the Agent.
• If using Save 22 then ensure QUSRSYS and QGPL is saved and Restore from tape before starting the Agent.
It is recommended to exclude QMPGDATA (Performance Data Library) from *ALLUSR Job in backups/restores.
Sample of *ALLUSR Restore log when library not excluded:

library QMPGDATA.
It is recommended NOT to run *SYS Backup and *ALLUSR backups at the same time. If *SYS Backup and *ALLUSR backups are running at the same time, you may receive various mutex errors in the *ALLUSR Backup log as some objects may be locked while the other process times out. Note that *SYS only runs a few minutes and can be run first.
