Total Backup Capacity: 10 GB
Objects: 20
% of incremental Backup Change 5,00%
Device concurrency: 16
Log level: All
Number of copies 0
Data protection: 52 Weeks

Figure 10 is a graphical representation of the above-described scenario. It shows in the blue box to
the left which parameter in the discussed datalist influences the IDB size/growth the most.
To estimate the size of the IDB use the Internal Database Capacity Planning Tool located at:
• On the UNIX Cell Managers:
/opt/omni/doc/C/IDB_capacity_planning.xls
• On the Windows Cell Manager:
<Data_Protector_home>\docs\IDB_capacity_planning.xls
You can also use this tool to estimate the size of the IDB in environments with online databases
(Oracle, SAP R/3).
