There are four significant changes to backup and restore:
An IQ full, incremental-since-full or incremental backup may be restricted to only the set of read-write files in the database using the READWRITE FILES ONLY keywords. The read-write files must be IQ dbspaces. For syntax and details, see BACKUP statement in Chapter 1, “SQL Statements,” in Reference: Statements and Options
An IQ backup may back up a set of read-only dbspaces and/or read-only files. The read-only dbspaces/files must be IQ dbspaces.
A restore of a backup may, optionally, restore only a subset of the dbspaces and/or files. The subset must be READONLY dbspaces and/or files. For syntax, see RESTORE statement in Chapter 1, “SQL Statements,” in Reference: Statements and Options.
System tables now contain backup history. See “SYSIQBACKUPHISTORY system view” and “SYSIQBACKUPHISTORYDETAIL system view” in Chapter 8, “System Views,” of Reference: Building Blocks, Tables, and Procedures.
