Major performance optimization for weekly DR tests: TestMode (weekly testing): - Copy ONLY latest full backup + everything after it - Includes: latest DAILY_FULL + incrementals + controlfiles + SPFILE - Excludes: older full backups (not needed for testing) - Benefit: ~60-70% reduction (14GB → 4-5GB) - Copy time: 2min → 30-45sec (saves ~1-1.5 min) - Risk: Low - testing only needs to verify latest backup works Standalone Mode (real DR): - Copy ALL backups (unchanged behavior) - Includes: all full backups + redundancy for fallback - Benefit: Maximum safety for disaster recovery - If latest backup corrupted → RMAN uses previous backup Implementation: - Finds latest *DAILY_FULL*.BKP (Level 0 backup) - Gets its timestamp - Copies all *.BKP files >= that timestamp - Automatic inclusion of incrementals, controlfiles, SPFILE backups Combined optimization results: - VM polling: saves 60-120s - Service preservation: saves 40s - Backup copy (TestMode): saves 60-90s Total: 160-250 seconds (2.5-4 minutes) per test Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
