**Generated:** 2025-10-09
**Last Updated:** 2025-10-10 03:25
**Status:** 🟡 FINAL TESTING IN PROGRESS - RMAN restore running
**Objective:** Implement cumulative incremental backups with Proxmox host storage for optimal RPO/RTO
**Target RPO:** 3-4 hours (vs current 24 hours)
**Target RTO:** 12-15 minutes (unchanged)

---

## ✅ IMPLEMENTATION STATUS

### Completed (2025-10-09 + 2025-10-10 Sessions)

#### Session 1 (2025-10-09 evening)
- ✅ **Phase 1:** Proxmox host storage configured (`/mnt/pve/oracle-backups/ROA/autobackup`)
- ✅ **Phase 2:** RMAN script already has `CUMULATIVE` keyword
- ✅ **Phase 3:** Transfer scripts updated to send to Proxmox (10.0.20.202:22, root)
  - Modified: `transfer_incremental.ps1` and `transfer_to_dr.ps1`
  - Changed from VM 109 (10.0.20.37:22122) to Proxmox host
  - Converted Windows PowerShell commands to Linux bash
- ✅ **VM 109 cleanup:** Deleted temporary files, old backups (~6.4 GB freed)
- ✅ **SSH Key Setup:** SSH key copied from PRIMARY to Proxmox
  - Existing key: `C:\Windows\System32\config\systemprofile\.ssh\id_rsa`
  - Copied to: Proxmox `/root/.ssh/authorized_keys`
  - SSH passwordless access working ✅
- ✅ **Phase 4:** Scheduled tasks modified on PRIMARY
  - Task 1: 02:30 FULL backup (unchanged)
  - Task 2: 13:00 CUMULATIVE backup (modified from 14:00)
  - Task 3: 18:00 CUMULATIVE backup (created)
  - All tasks now use Proxmox host as destination
- ✅ **Phase 5:** NFS mount point configured on VM 109 → **F:\ drive**
  - NFS server installed on Proxmox: `nfs-kernel-server`
  - NFS export configured: `/mnt/pve/oracle-backups → 10.0.20.37 (rw,no_root_squash)`
  - NFS Client enabled in Windows VM 109
  - Mount command: `mount -o rw,nolock,mtype=hard,timeout=60 10.0.20.202:/mnt/pve/oracle-backups F:`
  - PowerShell scheduled task created for auto-mount at startup (`D:\Oracle\Scripts\mount-nfs.bat`)
  - Permissions set to 777 on Proxmox directory
  - **Status:** F:\ mounts automatically at Windows startup ✅

#### Session 2 (2025-10-10 late night - MAJOR PROGRESS)
- ✅ **Phase 6:** Restore scripts updated to use F:\ mount
  - `rman_restore_final.cmd` modified to read backups from F:\ROA\autobackup
  - Scripts verify F:\ mount is accessible before starting restore
  - **FIXED:** Control file restore now uses `RESTORE CONTROLFILE FROM AUTOBACKUP`
  - All RMAN catalog commands point to F:\ mount
- ✅ **Phase 6.5:** Database cleanup strategy implemented (CRITICAL FEATURE)
  - **cleanup_database.cmd** created:
    - Deletes Oracle service completely
    - Deletes ALL database files (datafiles, control files, redo logs)
    - Deletes local FRA (backups safe on F:\)
    - Does NOT recreate service (service created during restore)
    - Leaves VM in completely clean state
  - **rman_restore_from_zero.cmd** created:
    - Step 1: Calls cleanup_database.cmd (clean state)
    - Step 2.1: Creates Oracle service from PFILE
    - Step 2.2: STARTUP NOMOUNT
    - Step 2.3: Generates RMAN restore script
    - Step 2.4: Runs RMAN restore (control file → mount → catalog → restore → recover → open)
    - Step 3: Verifies database
  - **Workflow documented:**
    - **Weekly test:** restore → test → cleanup → shutdown
    - **Real disaster:** restore → keep running (NO cleanup!)
  - Saves ~8 GB disk space after each test
  - Ensures repeatable, clean DR tests from zero
- ✅ **Backup transfer tested:**
  - Manual backup executed on PRIMARY
  - Transfer script successfully copied 6.7 GB to Proxmox
  - Backups verified accessible on F:\ in VM 109
- ✅ **Cleanup script tested:**
  - Successfully deletes all database files
  - Successfully removes Oracle service
  - VM confirmed in clean state (no service, no DB files)
- 🟡 **Restore script final test IN PROGRESS:**
  - **Key challenges solved:**
    - Issue 1: RMAN AUTOBACKUP doesn't work with backups on F:\ (NFS mount)
    - Solution: Copy ALL backups from F:\ to C:\Users\oracle\recovery_area before restore
    - Issue 2: Oracle service persists in registry after `sc delete`
    - Solution: Use `oradim -delete -sid ROA` + delete registry keys manually
  - **Current test status:**
    - Cleanup: ✅ PASSED (oradim delete works perfectly)
    - Service creation: ✅ PASSED
    - NOMOUNT: ✅ PASSED
    - Backup copy F:\ → recovery_area: ✅ PASSED (6.7 GB in ~2 min)
    - RMAN restore: ⏳ RUNNING NOW (expected ~10-15 min)
    - Expected completion: 2025-10-10 03:35-03:40

### Pending (Next Session)
- ⏳ **Phase 7:** Final end-to-end test (15-20 minutes)
  - Run `rman_restore_from_zero.cmd` with fixed control file restore
  - Verify database opens successfully
  - Test cleanup after successful restore
  - **Note:** Backup files already transferred to F:\ (6.7 GB)
  - **Issue found and fixed:** Control file restore now uses `RESTORE CONTROLFILE FROM AUTOBACKUP`

## 📋 EXECUTIVE SUMMARY

### Current State
- **Backup Strategy:** FULL daily (02:30), DIFFERENTIAL incremental (14:00)
- **Storage:** Backups transferred to VM 109 (powered OFF most of time)
- **RPO:** 24 hours (only FULL backup used for restore)
- **Issue:** DIFFERENTIAL incremental caused UNDO corruption during restore

### Proposed State
- **Backup Strategy:** FULL daily (02:30), CUMULATIVE incremental (13:00 + 18:00)
- **Storage:** Backups on Proxmox host (pveelite), mounted in VM 109 when needed
- **RPO:** 3-4 hours (using FULL + latest CUMULATIVE)
- **Benefit:** Simple, reliable restore without UNDO/SCN issues

### Why CUMULATIVE?
- ✅ **Simple restore:** FULL + last cumulative (no dependency chain)
- ✅ **No UNDO corruption:** Each cumulative is independent from Level 0
- ✅ **Better RPO:** Max 5 hours data loss (vs 24 hours)
- ✅ **Reliable:** No issues with missing intermediate backups

---

## 🎯 IMPLEMENTATION PHASES

### PHASE 1: Configure Proxmox Host Storage (15 minutes)

**Objective:** Create backup storage on pveelite host, accessible by VM 109 via mount point

**Steps:**

#### 1.1 Create backup directory on pveelite (SSH to host)
```bash
# On pveelite (10.0.20.202)
ssh root@10.0.20.202

# Create directory structure
mkdir -p /mnt/pve/oracle-backups/ROA/autobackup
chmod 755 /mnt/pve/oracle-backups
chmod 755 /mnt/pve/oracle-backups/ROA
chmod 755 /mnt/pve/oracle-backups/ROA/autobackup

# Verify
ls -la /mnt/pve/oracle-backups/ROA/autobackup
```

#### 1.2 Add mount point to VM 109 (Proxmox CLI)
```bash
# Stop VM 109 if running
qm stop 109

# Add mount point as additional storage
# This creates a VirtIO-9p mount point
qm set 109 -mp0 /mnt/pve/oracle-backups,mp=/mnt/oracle-backups

# Or via Proxmox Web UI:
# VM 109 → Hardware → Add → Mount Point
# - Source: /mnt/pve/oracle-backups
# - Mount point: /mnt/oracle-backups
# - Read-only: NO

# Start VM to test
qm start 109
```

#### 1.3 Verify mount in Windows VM
```powershell
# SSH to VM 109
ssh -p 22122 romfast@10.0.20.37

# Check if mount point appears as drive
# ⚠️ IMPORTANT: E:\ is already used in VM 109
# Mount will appear as F:\ (next available drive letter)
Get-PSDrive -PSProvider FileSystem

# Expected: C:, D:, E: (existing), F: (new mount from host)

# Verify mount path accessible
Test-Path F:\ROA\autobackup

# Create test file
New-Item -ItemType Directory -Path F:\ROA\autobackup -Force
echo "test" > F:\ROA\autobackup\test.txt

# Verify from host
exit
ssh root@10.0.20.202 "ls -la /mnt/pve/oracle-backups/ROA/autobackup/test.txt"

# Should show the test file - mount is working!
```

**⚠️ CRITICAL NOTE:**
- VM 109 already has E:\ partition
- Mount point will be **F:\** (not E:\)
- Update all scripts to use **F:\** instead of E:\

---

### PHASE 2: Modify RMAN Backup Scripts on PRIMARY (20 minutes)

**Objective:** Change incremental backups from DIFFERENTIAL to CUMULATIVE, add second daily incremental

#### 2.1 Găsește scriptul RMAN incremental existent
```powershell
# SSH to PRIMARY
ssh -p 22122 Administrator@10.0.20.36

cd D:\rman_backup

# Găsește scriptul incremental existent
Get-ChildItem *incr*.txt, *incr*.rman

# Ar trebui să vezi ceva gen:
# rman_backup_incremental.txt SAU
# rman_incremental.rman SAU similar
```

#### 2.2 Modifică scriptul EXISTENT - adaugă doar un cuvânt
**Fișier:** Scriptul incremental găsit la pasul 2.1 (ex: `D:\rman_backup\rman_backup_incremental.txt`)

**Modificare:** Găsește linia cu `INCREMENTAL LEVEL 1` și adaugă `CUMULATIVE`

**ÎNAINTE:**
```
BACKUP INCREMENTAL LEVEL 1 ...
```

**DUPĂ:**
```
BACKUP INCREMENTAL LEVEL 1 CUMULATIVE ...
```

**Asta e tot!** Un singur cuvânt adăugat.

**Exemplu complet (dacă scriptul arată așa):**
```
ÎNAINTE:
BACKUP INCREMENTAL LEVEL 1 AS COMPRESSED BACKUPSET DATABASE ...

DUPĂ:
BACKUP INCREMENTAL LEVEL 1 CUMULATIVE AS COMPRESSED BACKUPSET DATABASE ...
```

#### 2.3 Test manual
```powershell
# On PRIMARY
cd D:\rman_backup

# Rulează scriptul modificat
# Folosește numele scriptului tău existent!
rman cmdfile=rman_backup_incremental.txt log=logs\test_cumulative_$(Get-Date -Format 'yyyyMMdd_HHmmss').log

# Verifică că s-a creat backup
Get-ChildItem C:\Users\oracle\recovery_area\ROA\autobackup\*.bkp | Sort-Object LastWriteTime -Descending | Select-Object -First 3
```

---

### PHASE 3: Update Transfer Scripts (30 minutes)

**Objective:** Update transfer scripts to send backups to Proxmox host instead of VM

#### 3.1 Găsește scripturile de transfer existente
```powershell
# SSH to PRIMARY
ssh -p 22122 Administrator@10.0.20.36

cd D:\rman_backup

# Găsește scripturile de transfer
Get-ChildItem *transfer*.ps1

# Ar trebui să vezi:
# - transfer_to_dr.ps1 (pentru FULL)
# - transfer_incremental.ps1 SAU 02b_transfer_incremental_to_dr.ps1 (pentru INCREMENTAL)
```

#### 3.2 Modifică scripturile EXISTENTE - schimbă doar destinația
**Găsește în fiecare script aceste linii și modifică-le:**

**ÎNAINTE (transfer la VM):**
```powershell
$DRHost = "10.0.20.37"       # VM-ul
$DRPort = "22122"            # SSH pe VM
$DRUser = "romfast"          # User din VM
$DRPath = "D:/oracle/backups/primary"  # Path în VM
```

**DUPĂ (transfer la Proxmox host):**
```powershell
$DRHost = "10.0.20.202"      # pveelite HOST
$DRPort = "22"               # SSH standard pe host
$DRUser = "root"             # Root pe Proxmox
$DRPath = "/mnt/pve/oracle-backups/ROA/autobackup"  # Path pe host
```

**Asta e tot!** Doar 4 linii modificate în fiecare script.

#### 3.2 Setup SSH key for Proxmox host access
```powershell
# On PRIMARY (10.0.20.36)

# Generate SSH key for Proxmox host (if not exists)
ssh-keygen -t rsa -b 4096 -f C:\Users\Administrator\.ssh\id_rsa_pveelite -N ""

# Copy public key to Proxmox host
type C:\Users\Administrator\.ssh\id_rsa_pveelite.pub | ssh root@10.0.20.202 "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"

# Test connection
ssh -i C:\Users\Administrator\.ssh\id_rsa_pveelite root@10.0.20.202 "echo SSH_OK"
```

#### 3.3 Test transfer script
```powershell
# On PRIMARY
cd D:\rman_backup

# Test FULL backup transfer
.\02_transfer_to_pveelite_host.ps1 -BackupType FULL

# Verify on Proxmox host
ssh root@10.0.20.202 "ls -lh /mnt/pve/oracle-backups/ROA/autobackup/*.bkp"

# Test INCREMENTAL backup transfer
.\02_transfer_to_pveelite_host.ps1 -BackupType INCREMENTAL
```

---

### PHASE 4: Update Scheduled Tasks on PRIMARY (20 minutes)

**Objective:** Create/update scheduled tasks for 2 cumulative incremental backups per day

#### 4.1 View current scheduled tasks
```powershell
# On PRIMARY
Get-ScheduledTask | Where-Object {$_.TaskName -like "*Oracle*"} | Select-Object TaskName, State, @{N='NextRun';E={(Get-ScheduledTaskInfo $_).NextRunTime}}
```

#### 4.2 Găsește task-ul incremental existent (14:00)
```powershell
# On PRIMARY
Get-ScheduledTask | Where-Object {$_.TaskName -like "*incr*" -or $_.TaskName -like "*14*"} | Select-Object TaskName, State

# Notează numele exact al task-ului
```

#### 4.3 Modifică task-ul 14:00 → 13:00 (primul incremental)
```powershell
# Folosește numele găsit mai sus
$taskName = "Oracle RMAN Incremental Backup"  # ÎNLOCUIEȘTE cu numele real!

# Schimbă doar ora: 14:00 → 13:00
$trigger = New-ScheduledTaskTrigger -Daily -At "13:00"

$task = Get-ScheduledTask -TaskName $taskName
Set-ScheduledTask -TaskName $taskName -Trigger $trigger
```

#### 4.4 Clonează task-ul pentru al doilea incremental (18:00)
```powershell
# Exportă task-ul existent
$task = Get-ScheduledTask -TaskName $taskName
$xml = [xml](Export-ScheduledTask -TaskName $taskName)

# Modifică ora în XML
$xml.Task.Triggers.CalendarTrigger.StartBoundary = $xml.Task.Triggers.CalendarTrigger.StartBoundary -replace "T13:00:", "T18:00:"

# Importă ca task nou
Register-ScheduledTask -TaskName "$taskName 1800" -Xml $xml.OuterXml

# Sau mai simplu - copiază task-ul din Task Scheduler GUI și schimbă ora
```

#### 4.5 Verifică toate task-urile
```powershell
# Ar trebui să vezi 3 task-uri Oracle:
# 1. FULL (02:30) - neschimbat
# 2. INCREMENTAL (13:00) - modificat din 14:00
# 3. INCREMENTAL (18:00) - clonat din 13:00

Get-ScheduledTask | Where-Object {$_.TaskName -like "*Oracle*"} |
    Select-Object TaskName, State, @{N='NextRun';E={(Get-ScheduledTaskInfo $_).NextRunTime}} |
    Format-Table -AutoSize
```

#### 4.5 Verify all tasks
```powershell
# List all Oracle tasks
Get-ScheduledTask | Where-Object {$_.TaskName -like "*Oracle*"} |
    Select-Object TaskName, State, @{N='NextRun';E={(Get-ScheduledTaskInfo $_).NextRunTime}} |
    Format-Table -AutoSize

# Expected tasks:
# 1. Oracle RMAN Full Backup 0230       - Daily 02:30
# 2. Oracle RMAN Cumulative Backup 1300 - Daily 13:00
# 3. Oracle RMAN Cumulative Backup 1800 - Daily 18:00
```

---

### PHASE 5: Configure NFS Mount Point on VM 109 (30 minutes) ✅ COMPLETED

**Objective:** Mount Proxmox backup storage as F:\ drive in Windows VM using NFS

**Status:** ✅ COMPLETED on 2025-10-10

#### 5.1 Install and configure NFS server on Proxmox
```bash
# SSH to Proxmox host
ssh root@10.0.20.202

# Install NFS server
apt install -y nfs-kernel-server

# Configure NFS export
echo '/mnt/pve/oracle-backups 10.0.20.37(rw,sync,no_subtree_check,no_root_squash)' >> /etc/exports

# Apply export configuration
exportfs -ra

# Set permissions for Windows compatibility
chmod -R 777 /mnt/pve/oracle-backups

# Verify export
showmount -e localhost
# Expected output: /mnt/pve/oracle-backups 10.0.20.37
```

#### 5.2 Enable NFS Client in Windows VM 109
```powershell
# SSH to VM 109
ssh -p 22122 romfast@10.0.20.37

# Enable NFS Client feature
Enable-WindowsOptionalFeature -Online -FeatureName ServicesForNFS-ClientOnly -All -NoRestart
Enable-WindowsOptionalFeature -Online -FeatureName ClientForNFS-Infrastructure -All -NoRestart
Enable-WindowsOptionalFeature -Online -FeatureName NFS-Administration -All -NoRestart

# Verify installation
Get-WindowsOptionalFeature -Online | Where-Object {$_.FeatureName -like "*NFS*"}
```

#### 5.3 Create PowerShell mount script with auto-retry
```powershell
# Create Scripts directory
mkdir C:\Scripts

# Create mount script
notepad C:\Scripts\mount-nfs.ps1
```

**Content of `C:\Scripts\mount-nfs.ps1`:**
```powershell
Start-Sleep -Seconds 10

# Wait for NFS Client service
$timeout = 60
$elapsed = 0
while ($elapsed -lt $timeout) {
    $nfsService = Get-Service | Where-Object {$_.Name -like "*NFS*" -and $_.Status -eq "Running"}
    if ($nfsService) { break }
    Start-Sleep -Seconds 5
    $elapsed += 5
}

# Unmount F: if exists
try { & umount F: 2>$null } catch {}

# Mount NFS share
Start-Sleep -Seconds 5
& mount -o rw,nolock,mtype=hard,timeout=60 10.0.20.202:/mnt/pve/oracle-backups F:

# Log result
"$(Get-Date) - Mount completed" | Out-File C:\Scripts\mount-nfs.log -Append
```

#### 5.4 Create scheduled task for auto-mount at startup
```cmd
# Create scheduled task (run in CMD as Administrator)
schtasks /create /tn "Mount NFS F" /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\mount-nfs.ps1" /sc onstart /ru SYSTEM /rl HIGHEST /delay 0000:30 /f

# Verify task creation
schtasks /query /tn "Mount NFS F"

# Test manual mount
mount -o rw,nolock,mtype=hard,timeout=60 10.0.20.202:/mnt/pve/oracle-backups F:

# Verify mount
dir F:\ROA\autobackup
```

#### 5.5 Verification checklist
- [x] NFS server running on Proxmox (port 2049)
- [x] Export visible: `showmount -e 10.0.20.202`
- [x] Windows NFS Client services enabled
- [x] F:\ drive mounts successfully with manual command
- [x] Scheduled task runs at startup
- [x] F:\ persists after VM reboot
- [x] Can create/read/write files on F:\ROA\autobackup

**⚠️ IMPORTANT NOTES:**
- NFS uses IP-based authentication (no username/password)
- Only VM 109 (10.0.20.37) can access the share
- `no_root_squash` allows Windows to write as root
- Permissions 777 on Proxmox ensure Windows compatibility
- Mount point is **F:\** (not E:\, which is already in use)

---

### PHASE 6: Update DR Restore Script (30 minutes)

**Objective:** Update restore script to read backups from F:\ mount point and handle cumulative backups

#### 6.1 Modifică scriptul de restore existent pentru cumulative backups
**Fișier:** `D:\oracle\scripts\rman_restore_final.cmd` (scriptul tău existent)

**Modificări necesare:**

**1. Schimbă locația backup-urilor:**
```cmd

```

**2. Verifică că mount point-ul e accesibil:**
Adaugă la început:
```cmd

### PHASE 6.5: Database Cleanup Strategy - Restore from Zero (NEW)

**Objective:** Keep DR VM clean by restoring from zero each time (no old database files, no Oracle services)

**Why this approach?**
- ✅ **Repeatable testing:** Each test starts from known clean state
- ✅ **No leftovers:** No old control files, redo logs, or datafiles
- ✅ **True DR test:** Simulates real disaster scenario (no database, only Oracle software)
- ✅ **No manual cleanup:** Automated cleanup before and after each test
- ✅ **Save disk space:** Delete 8+ GB of database files after each test

#### 6.5.1 Cleanup Steps (BEFORE restore)

**What to delete:**
```cmd
REM 1. Stop and delete Oracle service
sc stop OracleServiceROA 2>nul
sc delete OracleServiceROA 2>nul

REM 2. Delete all database files (datafiles, control files, redo logs)
del /Q C:\Users\oracle\oradata\ROA\*.dbf 2>nul
del /Q C:\Users\oracle\oradata\ROA\*.ctl 2>nul
del /Q C:\Users\oracle\oradata\ROA\*.log 2>nul

REM 3. Delete local FRA (backups are on F:\ now, safe to delete)
rmdir /S /Q C:\Users\oracle\recovery_area\ROA 2>nul
mkdir C:\Users\oracle\recovery_area\ROA

REM 4. Delete old trace files (optional, saves space)
del /Q C:\Users\oracle\diag\rdbms\roa\ROA\trace\*.* 2>nul

REM 5. Recreate Oracle service from pfile
oradim -new -sid ROA -startmode manual -pfile C:\Users\oracle\admin\ROA\pfile\initROA.ora
```

**Result:** Clean VM with:
- ✅ Oracle software installed
- ✅ PFILE exists: `C:\Users\oracle\admin\ROA\pfile\initROA.ora`
- ✅ Oracle service created: `OracleServiceROA`
- ❌ No database files (will be restored)
- ❌ No control files (will be restored)
- ❌ No datafiles (will be restored)

#### 6.5.2 Cleanup Steps (AFTER successful restore test)

**Purpose:** Leave VM clean for next test, conserve disk space

```cmd
REM After verifying database is working:

REM 1. Shutdown database
sqlplus / as sysdba <<EOF
SHUTDOWN ABORT;
EXIT;
EOF

REM 2. Delete Oracle service
sc stop OracleServiceROA
sc delete OracleServiceROA

REM 3. Delete all database files
del /Q C:\Users\oracle\oradata\ROA\*.dbf
del /Q C:\Users\oracle\oradata\ROA\*.ctl
del /Q C:\Users\oracle\oradata\ROA\*.log
rmdir /S /Q C:\Users\oracle\recovery_area\ROA

REM 4. VM is now clean and ready for next test
echo Database cleanup complete - VM ready for next test
```

#### 6.5.3 Modified restore workflow

**OLD workflow (problematic):**
```
1. Start VM → database files exist from previous test
2. Shutdown existing database
3. Delete control files manually
4. Restore → may fail if old files interfere
5. Manually cleanup after test
```

**NEW workflow (clean and repeatable):**
```
1. Start VM → clean state (no database, only software)
2. Cleanup script: delete any leftover files + recreate service
3. Restore from F:\ backups → fresh database
4. Verify and test
5. Cleanup script: delete database files
6. Shutdown VM → ready for next test
```

#### 6.5.4 Scripts created and their usage

**File 1:** `D:\oracle\scripts\cleanup_database.cmd`
- **Purpose:** Standalone cleanup script
- **What it does:**
  - Stops and deletes Oracle service
  - Deletes all database files (datafiles, control files, redo logs)
  - Deletes local FRA (backups are on F:\, safe to delete)
  - Recreates Oracle service from PFILE
- **When to use:**
  - Before weekly test restore (to start from clean state)
  - After weekly test restore (to clean up and save disk space)
  - Manual cleanup when needed
- **Never use:** In real disaster scenario (you want to keep the database!)

**File 2:** `D:\oracle\scripts\rman_restore_from_zero.cmd`
- **Purpose:** Full restore workflow (cleanup BEFORE restore only)
- **What it does:**
  - Calls cleanup_database.cmd at START
  - Verifies F:\ mount is accessible
  - Restores database from F:\ backups
  - Opens database with RESETLOGS
  - Verifies database is working
  - Does NOT cleanup after restore (database remains running)
- **When to use:**
  - Weekly test restore (then manually run cleanup_database.cmd after testing)
  - **Real disaster scenario** (database remains running for production use)
- **Result:** Database is OPEN and ready to use

**File 3:** `D:\oracle\scripts\rman_restore_final.cmd` (legacy)
- **Purpose:** Restore without cleanup (assumes database files may exist)
- **When to use:** Only if rman_restore_from_zero.cmd fails
- **Recommendation:** Use rman_restore_from_zero.cmd instead

#### 6.5.5 Usage workflows

**A. Weekly Test Restore (Saturday morning):**
```cmd
REM 1. Start VM and verify F:\ mount
dir F:\ROA\autobackup

REM 2. Run restore (includes cleanup before restore)
D:\oracle\scripts\rman_restore_from_zero.cmd

REM 3. Verify database is working
sqlplus / as sysdba
SQL> SELECT * FROM V$DATABASE;

REM 4. Test application connectivity (optional)

REM 5. Cleanup after test to free disk space
D:\oracle\scripts\cleanup_database.cmd

REM 6. Shutdown VM
shutdown /s /t 60
```

**B. Real Disaster Scenario (production restore):**
```cmd
REM 1. Start VM and verify F:\ mount
dir F:\ROA\autobackup

REM 2. Run restore (includes cleanup before restore)
D:\oracle\scripts\rman_restore_from_zero.cmd

REM 3. Database is now OPEN and ready for production use
REM    DO NOT run cleanup_database.cmd after this!

REM 4. Update application connection strings to point to DR VM
REM 5. Keep VM running for production use
```

**C. Manual cleanup (when VM gets full):**
```cmd
REM Run cleanup to free ~8 GB disk space
D:\oracle\scripts\cleanup_database.cmd
```

#### 6.5.6 Important notes

⚠️ **CRITICAL: cleanup_database.cmd deletes the entire database!**
- Use it BEFORE weekly test restore (to start clean)
- Use it AFTER weekly test restore (to free disk space)
- **NEVER use it after a real disaster restore!** (you need the database running!)

✅ **For weekly tests:**
- Run: `rman_restore_from_zero.cmd` → test → `cleanup_database.cmd` → shutdown VM
- Result: VM is clean and ready for next test

✅ **For real disaster:**
- Run: `rman_restore_from_zero.cmd` → database is ready → **DO NOT cleanup!**
- Result: Database remains running for production use

### PHASE 7: Weekly Test Procedure (1 hour first time, 30 min ongoing)

**Objective:** Document weekly test procedure using new cumulative backup strategy

#### 7.1 Test procedure (run on Saturday morning)
```bash
# On Linux workstation or any machine with SSH to Proxmox

# Step 1: Verify latest backups on host (5 min)
ssh root@10.0.20.202 "ls -lth /mnt/pve/oracle-backups/ROA/autobackup/*.bkp | head -10"

# Expected to see:
# - FULL backup from this morning (02:30)
# - CUMULATIVE from yesterday 18:00
# - CUMULATIVE from yesterday 13:00
# - Older files...

# Step 2: Start DR VM (2 min)
ssh root@10.0.20.202 "qm start 109"

# Wait for Windows boot
sleep 180

# Verify VM is up
ping -c 3 10.0.20.37

# Step 3: Verify mount point in VM (2 min)
ssh -p 22122 romfast@10.0.20.37 "Get-ChildItem E:\oracle-backups\ROA\autobackup\*.bkp | Measure-Object"

# Should show ~10-15 backup files

# Step 4: Run restore (15-20 min)
ssh -p 22122 romfast@10.0.20.37 "D:\oracle\scripts\rman_restore_cumulative.cmd"

# Monitor restore progress

Copy-Item transfer_incremental_ORIGINAL.ps1 transfer_incremental.ps1 -Force
Copy-Item transfer_to_dr_ORIGINAL.ps1 transfer_to_dr.ps1 -Force

# Verifică că s-au restaurat
Get-Content rman_backup_incremental.txt | Select-String "CUMULATIVE"
# Nu ar trebui să găsească nimic dacă restaurarea a reușit
```

### Rollback Step 2: Restaurează task-urile originale
```powershell
# Șterge task-ul nou de la 18:00
Unregister-ScheduledTask -TaskName "Oracle RMAN Incremental Backup 1800" -Confirm:$false

# Restaurează task-ul de la 13:00 înapoi la 14:00
$taskName = "Oracle RMAN Incremental Backup"  # Numele task-ului tău
$trigger = New-ScheduledTaskTrigger -Daily -At "14:00"
Set-ScheduledTask -TaskName $taskName -Trigger $trigger

# SAU restaurează din backup XML
Register-ScheduledTask -Xml (Get-Content "D:\rman_backup\backup_tasks\Oracle RMAN Incremental Backup.xml") -Force

```

**Known issues (ALL FIXED):**
- ❌ ~~Log file name~~ → ✅ Fixed: simple name
- ❌ ~~Control file wildcard~~ → ✅ Fixed: AUTOBACKUP

**IMPORTANT - Backup manual înainte de modificări:**
Fă backup MANUAL la fișierele pe care le vei modifica:
```powershell
# Pe PRIMARY, copiază fișierele EXISTENTE înainte de modificare:
cd D:\rman_backup
Copy-Item rman_backup_incremental.txt rman_backup_incremental_ORIGINAL.txt
Copy-Item transfer_incremental.ps1 transfer_incremental_ORIGINAL.ps1
Copy-Item transfer_to_dr.ps1 transfer_to_dr_ORIGINAL.ps1

# Exportă task-urile
Get-ScheduledTask | Where-Object {$_.TaskName -like "*Oracle*"} | ForEach-Object {
    Export-ScheduledTask -TaskName $_.TaskName | Out-File "D:\rman_backup\backup_tasks\$($_.TaskName).xml"
}
```

**Dacă ceva nu merge, restaurezi din aceste copii!**
