Objectives • Discuss OnTape vs. OnBar • What is OnBar? • OnBar Backup & Restore Options • What’s Backed Up (And Not) • OnBar Configuration Parameters • Tuning OnBar Backups • External OnBar Restores • Storage Manager Integration
OnTape vs. OnBar OnBar • Parallel Backup/Restore • Reduced Backup Window • Faster Recovery • Storage Manager Integration OnTape • Reliable Backup • Simple Operation • Easy Configuration • Simple Tape Rotation
What is OnBar? IDS OnBar Storage Manager Archive XBSA API API DB Spaces Media Devices Sysutils DB
OnBar Backup Options • Whole System • DB Space Backup • Full/Incremental (Level 1,2) • Fake Backup
OnBar Restore Options • Cold Restore • Warm Restore • Physical Restore • Logical Restore • Point-in-Time Restore
What’s Backed Up(And Not) • OnBar Backup includes: • DB Space • Logical Log • Blobspace • Additional Files Required to Restore • ONCONFIG • ixbar.servernum • oncfg_servername.servernum • sm_versions • sqlhosts file • services file
OnBar Configuration Parameters BAR_BSALIB_PATH XBSA library path BAR_ACT_LOG OnBar activity log BAR_MAX_BACKUP Max # of process / onbar command BAR_RETRY Number of retries on failed attempt BAR_NB_XPORT_COUNT # of shared-memory data buffers BAR_XFER_BUF_SIZE Buffer size uses to exchange data with onbar_d process LTAPEDEV Logical log tape device LBU_PRESERVE Logical log block for onbar process ALARMPROGRAM Script execute when logical log fills RESTARTABLE_RESTORE Option to allow restore restart
Tuning OnBar Backups • Physical Database Configuration • Backup Parallelism • Thread Manipulation • Tape Drive Utilization • Transfer Data Buffers
External OnBar Restores • Configure Informix Environment • Copy ONCONFIG File • Add SQLHOSTS Entry • Services Entry (etc/services) • Copy ONBar Backup Files • ixbar.servernum • oncfg_servername.servernum • Point to Storage Manager • Execute Restore Command
Storage Manager Integration • Informix Storage Manager (ISM) • Veritas Net Backup • HP OmniBack • Other Third Party Vendors
