- Add FORMAT to rman_backup.txt: L0_*, ARC_*, SPFILE_*, CF_* - Add FORMAT to rman_backup_incremental.txt: L1_*, ARC_*, SPFILE_*, CF_* - Update rman_restore_from_zero.ps1 TestMode to select files by naming convention - Select only latest L0 backup set + all L1 incrementals/archives (faster DR tests) - Backward compatible with old autobackup naming (fallback to copy all) - Fixes missing datafiles issue (previously only copied 8 files, now copies full backup set) Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>
