A database online backup can be made during normal HPSS operation Online backup on test core /hpss_src/scripts/db2_fullbackup.ksh -p /db2_backup -t online -b none >>/db2_backup/db2_backup_fullbackup.out Online DB2 backup on productive core /hpss_src/scripts/db2_fullbackup.ksh -p / -t online -b none >>/db2_backup1/db2_fullbackup.out 2>&1
DB2 backup on active core
On the active core server runs every hour a cron job which takes an online DB2 backup: 0 */1 * * * if [ `hostname` == "hpsscr" ] ; then /hpss_src/scripts/db2_fullbackup.ksh -p /db2_backup1 -s /db2_backup2 -t online -b none >> /db2_backup1/db2_fullbackup.out 2>&1 ; fi For a DB2 restore see: Database Restore exercised on Test Core
DB2 backups are saved on /db2_backup1 and a copy is made on /db2_backup2 DB2 backups are kept on disks 7 days Every day a TSM backup puts the DB2 backups in TSM A deleted DB2 backup from local file system remains 60 more days in TSM => we can go back 67 days with a DB2 restore
Notice It is possible to archive the DB2 backups in TSM if a longer retention time is needed
