NetBackup for DB2 stream-based operations
Stream-based operations are the conventional method used by DB2 and NetBackup to backup and restore the database. Log archiving using the VENDOR method is also stream-based.
During a stream-based backup, the DB2 server processes (e.g. db2agent, db2bm, db2med) read the DB2 file contents into buffers. The stream of buffers is passed to NetBackup and transported to storage. At restore time, NetBackup fetches the buffers from storage and returns them to the DB2 server processes which write them back to the file system.
If the DB2 command line or NetBackup for DB2 template is configured to use multiple sessions, then there are multiple streams of buffers. Each stream of buffers is a unique application backup job and is cataloged as a unique backup image.
Figure: NetBackup for DB2 stream-based backup or restore represents a stream-based backup or restore.
