-| Volume Name | Container Mount | Purpose | Can Be Bind Mounted |

-| `ac_mysql_data` | `/var/lib/mysql` | MySQL database files | ✅ Yes - For backup/migration |
-| `ac_data` | `/azerothcore/data` | Game data (maps, vmaps, etc.) | ✅ Yes - Required for data files |

-| `ac_logs` | `/azerothcore/logs` | Application logs | ✅ Yes - For log analysis |

+| Storage Component | Local Path | Production Path | Purpose |

+| **Metrics Data** | `./storage/azerothcore/azerothcore/influxdb` | `${STORAGE_ROOT}/azerothcore/azerothcore/influxdb` | InfluxDB time series data |

-To use bind mounts instead of named volumes, modify the compose file:
+### Storage Configuration Examples
 
-```yaml
-volumes:
-  # Replace named volume with bind mount
-  - /srv/azerothcore/mysql:/var/lib/mysql
-  - /srv/azerothcore/data:/azerothcore/data
-  - /srv/azerothcore/config:/azerothcore/env/dist/etc
-  - /srv/azerothcore/logs:/azerothcore/logs
-  - /srv/azerothcore/backups:/backups
+#### Local Development
+```bash
+# All data stored locally in ./storage/
+STORAGE_ROOT=./storage
 ```
 
+#### Production with NFS
+```bash
+# All data on NFS mount
+STORAGE_ROOT=/nfs/containers
+```
+
+#### Custom Mount Point
+```bash
+# All data on dedicated storage mount
+STORAGE_ROOT=/mnt/azerothcore-data
+```
+
+### Unified Storage Benefits
+
+✅ **Single Mount Point**: Only need to mount one directory in production
+✅ **Simplified Backup**: All persistent data in one location
+✅ **Easy Migration**: Copy entire `${STORAGE_ROOT}/azerothcore` directory
+✅ **Consistent Paths**: All layers use same storage root
+✅ **Environment Flexibility**: Change storage location via single variable
+
 ### Volume Backup Procedures
 
-#### Backup MySQL Data:
+#### Complete Storage Backup:
 ```bash
-# Create backup of MySQL volume
-docker run --rm \
-  -v ac_mysql_data:/data \
-  -v $(pwd):/backup \
-  alpine tar czf /backup/mysql-backup-$(date +%Y%m%d).tar.gz -C /data .
+# Backup entire storage directory (recommended)
+tar czf azerothcore-storage-backup-$(date +%Y%m%d).tar.gz storage/
+
+# Or backup to remote location
+rsync -av storage/ backup-server:/backups/azerothcore/$(date +%Y%m%d)/
 ```
 
-#### Backup Game Data:
+#### Component-Specific Backups:
 ```bash
-# Create backup of game data volume
-docker run --rm \
-  -v ac_data:/data \
-  -v $(pwd):/backup \
-  alpine tar czf /backup/gamedata-backup-$(date +%Y%m%d).tar.gz -C /data .
+# Backup just database files
+tar czf mysql-backup-$(date +%Y%m%d).tar.gz storage/azerothcore/mysql-data/
+
+# Backup just game data
+tar czf gamedata-backup-$(date +%Y%m%d).tar.gz storage/azerothcore/data/
+
+# Backup just configuration
+tar czf config-backup-$(date +%Y%m%d).tar.gz storage/azerothcore/config/
+```
+
+#### Production Storage Backup:
+```bash
+# When using custom STORAGE_ROOT
+source docker-compose-azerothcore-database.env
+tar czf azerothcore-backup-$(date +%Y%m%d).tar.gz ${STORAGE_ROOT}/azerothcore/
 ```
