IDB architecture
The IDB is an internal database located on the Data Protector Cell Manager that keeps information
regarding what data is backed up; on which media it resides; the result of backup, restore, copy, object
consolidation, and media management sessions; and which devices and libraries are configured.
What is the IDB used for?
The information stored in the IDB enables the following:
• Fast and convenient restore: You are able to browse the files and directories to be restored. You
can quickly find the media required for a restore and therefore make the restore much faster.
• Backup management: You can verify the result of backup sessions.
• Media management: You can allocate media during backup, copy, and object consolidation
sessions, track media management operations and media attributes, group media in different media
pools, and track media location in tape libraries.
