Features

Backup Strategies

Full Backup

Complete backup of all specified memory layers
Serves as baseline for incremental and differential backups
Highest storage requirement but fastest recovery
Recommended frequency: Daily or weekly

backup = await backup_system.create_backup(
    memory_layers=memory_layers,
    strategy=BackupStrategy.FULL,
    storage_backend=StorageBackend.S3,
    tags={'type': 'scheduled', 'frequency': 'daily'}
)

Incremental Backup

Backs up only files modified since last backup (any type)
Smallest storage requirement
Requires chain of backups for complete recovery
Recommended frequency: Hourly

backup = await backup_system.create_backup(
    memory_layers=memory_layers,
    strategy=BackupStrategy.INCREMENTAL,
    storage_backend=StorageBackend.LOCAL
)

Differential Backup

Backs up files modified since last full backup
Moderate storage requirement
Requires only full backup + latest differential for recovery
Recommended frequency: Every 4-6 hours

backup = await backup_system.create_backup(
    memory_layers=memory_layers,
    strategy=BackupStrategy.DIFFERENTIAL,
    storage_backend=StorageBackend.AZURE
)

Usage Examples

Basic Backup Operations

Creating a Backup

from memory_backup_system import MemoryBackupSystem, BackupStrategy

# Initialize backup system
config = {
    'backup_dir': '/nova/backups',
    'storage': {
        'local_path': '/nova/backup_storage'
    },
    'retention_days': 30
}
backup_system = MemoryBackupSystem(config)

# Create backup
memory_layers = [
    '/nova/memory/layer_01.json',
    '/nova/memory/layer_02.json',
    '/nova/memory/consciousness_state.json'
]

backup = await backup_system.create_backup(
    memory_layers=memory_layers,
    strategy=BackupStrategy.FULL,
    tags={'environment': 'production', 'priority': 'high'}
)

print(f"Backup created: {backup.backup_id}")
print(f"Compression ratio: {backup.compressed_size / backup.original_size:.2%}")

Listing Backups

# List all backups
all_backups = await backup_system.list_backups()

# Filter by strategy
full_backups = await backup_system.list_backups(
    strategy=BackupStrategy.FULL,
    limit=10
)

# Filter by status
completed_backups = await backup_system.list_backups(
    status=BackupStatus.COMPLETED
)

Deleting Old Backups

# Manual deletion
success = await backup_system.delete_backup(backup_id)

# Automatic cleanup
cleaned_count = await backup_system.cleanup_old_backups(retention_days=30)
print(f"Cleaned up {cleaned_count} old backups")

Disaster Recovery Operations

Triggering Recovery

from disaster_recovery_manager import DisasterRecoveryManager, DisasterType, RecoveryMode

# Initialize recovery manager
recovery_config = {
    'recovery_dir': '/nova/recovery',
    'rpo_targets': rpo_targets,
    'rto_targets': rto_targets
}
recovery_manager = DisasterRecoveryManager(recovery_config, backup_system)

# Trigger recovery
recovery = await recovery_manager.trigger_recovery(
    disaster_type=DisasterType.DATA_CORRUPTION,
    affected_layers=affected_memory_layers,
    recovery_mode=RecoveryMode.AUTOMATIC,
    target_timestamp=datetime.now() - timedelta(hours=1)  # Point-in-time recovery
)

print(f"Recovery initiated: {recovery.recovery_id}")

Testing Recovery Process

# Test recovery without affecting production
test_results = await recovery_manager.test_recovery(
    test_layers=test_memory_layers,
    backup_id=specific_backup_id
)

print(f"Recovery test success: {test_results['success']}")
print(f"RTO achieved: {test_results['rto_achieved_minutes']} minutes")
print(f"RPO achieved: {test_results['rpo_achieved_minutes']} minutes")

Integrity Checking

File Integrity Verification

from backup_integrity_checker import BackupIntegrityChecker, IntegrityLevel

# Initialize integrity checker
integrity_config = {
    'integrity_dir': '/nova/integrity',
    'monitor_files': critical_memory_files
}
integrity_checker = BackupIntegrityChecker(integrity_config, backup_system)

# Check single file
result = await integrity_checker.check_file_integrity(
    '/nova/memory/critical_layer.json',
    IntegrityLevel.COMPREHENSIVE,
    expected_metadata={'sha256_checksum': expected_hash}
)

print(f"Integrity status: {result.status.value}")
for issue in result.issues:
    print(f"  Issue: {issue.corruption_type.value} - {issue.description}")

Backup Integrity Verification

# Check entire backup integrity
integrity_results = await integrity_checker.check_backup_integrity(
    backup_id=backup.backup_id,
    integrity_level=IntegrityLevel.CHECKSUM
)

# Check multiple files concurrently
multi_results = await integrity_checker.check_multiple_files(
    file_paths=memory_layers,
    integrity_level=IntegrityLevel.CONTENT,
    max_concurrent=4
)

Integrity Issue Repair

# Attempt to repair detected issues
if result.issues:
    repair_success = await integrity_checker.attempt_repair(result)
    if repair_success:
        print("File successfully repaired")
    else:
        print("Repair failed - restore from backup required")

Monitoring and Reporting

Background Monitoring

# Start continuous monitoring
await backup_system.start_background_tasks()
await recovery_manager.start_monitoring()
await integrity_checker.start_monitoring(check_interval_minutes=60)

# Stop monitoring
await backup_system.stop_background_tasks()
await recovery_manager.stop_monitoring()
await integrity_checker.stop_monitoring()

Integrity Reporting

# Generate comprehensive integrity report
report = await integrity_checker.generate_integrity_report(
    file_paths=critical_files,
    include_passed=False  # Only show issues
)

print(f"Total checks: {report['total_checks']}")
print(f"Files with issues: {len(report['files_with_issues'])}")
print(f"Corruption types: {report['corruption_types']}")
