WIP: Oracle DR CUMULATIVE backup upgrade - Phases 1-3 completed
COMPLETED: - Phase 1: Proxmox host storage (/mnt/pve/oracle-backups/ROA/autobackup) - Phase 2: RMAN script already has CUMULATIVE keyword - Phase 3: Transfer scripts updated for Proxmox host * transfer_incremental.ps1: 10.0.20.37:22122 → 10.0.20.202:22 * transfer_to_dr.ps1: Same change * Converted Windows PowerShell to Linux bash commands - VM 109 cleanup: ~6.4 GB freed, RMAN catalog cleaned NEW FILES: - copy_existing_key_to_proxmox.ps1: Setup script for SSH key - setup_ssh_keys_for_proxmox.ps1: Alternative setup (not used) PENDING (Next Session): - Run copy_existing_key_to_proxmox.ps1 on PRIMARY as Administrator - Phase 4: Modify scheduled tasks (13:00 + 18:00) - Phase 5: Configure mount point on VM 109 (F:\ drive) - Phase 6: Update restore script for F:\ mount - Phase 7: Test FULL + CUMULATIVE backup and restore DOCUMENTATION: - DR_UPGRADE_TO_CUMULATIVE_PLAN.md: Added implementation status 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
