Backup Procedures

1. Daily Backup Operations

Automated Backups

# Example backup script structure
# Schedule: Daily at 2:00 AM
1. Pre-backup validation checks
2. Database consistency checks
3. Incremental file system backup
4. Application-specific backups
5. Backup verification and validation
6. Email notification to IT team

Manual Verification Steps

• Backup job completion status
• Backup file size and integrity verification
• Error log review and analysis
• Storage capacity monitoring
• Offsite backup synchronization status

2. Weekly Full Backup Process

System Preparation

1. Service Coordination: Notify users of potential performance impact
2. Resource Verification: Ensure adequate storage space and bandwidth
3. System Health Check: Verify all systems are running optimally
4. Dependency Mapping: Identify system interdependencies

Backup Execution

1. Database Backups:

   • SQL Server: Full database backup with transaction log backup
   • Oracle: RMAN full backup with archive log backup
   • MongoDB: mongodump with consistent point-in-time backup

2. File System Backups:

   • Windows Servers: Windows Server Backup or third-party tools
   • Linux Servers: rsync, tar, or enterprise backup solutions
   • Network Attached Storage: Snapshot-based backups

3. Application Backups:

   • Configuration files and settings
   • Application logs and audit trails
   • Custom scripts and automation tools

3. Backup Validation and Testing

Automated Validation

• Backup file integrity checks (checksums)
• Restoration test sampling (10% of backups monthly)
• Backup catalog verification
• Storage system health monitoring

Monthly Recovery Testing

• Select random backup sets for full restoration testing
• Document recovery time and any issues encountered
• Verify data integrity and application functionality
• Update recovery procedures based on test results

Recovery Procedures

1. Recovery Planning

Recovery Assessment

• Incident Classification: Determine cause and scope of data loss
• Impact Analysis: Evaluate business impact and recovery priorities
• Recovery Strategy: Select appropriate recovery method and timeline
• Resource Requirements: Identify personnel, hardware, and software needs

Recovery Decision Matrix

2. System Recovery Process

Phase 1: Infrastructure Recovery (0-2 hours)

1. Hardware Assessment: Verify or replace failed hardware
2. Network Connectivity: Establish network connections and routing
3. Base Operating System: Install or restore OS from backup
4. Security Configuration: Apply security patches and configurations

Phase 2: Data Recovery (2-6 hours)

1. Database Restoration:

   -- Example SQL Server restore process
   RESTORE DATABASE [ProductionDB] 
   FROM DISK = 'C:\Backups\ProductionDB_Full.bak'
   WITH REPLACE, NORECOVERY
   
   RESTORE LOG [ProductionDB] 
   FROM DISK = 'C:\Backups\ProductionDB_Log.trn'
   WITH RECOVERY
   

2. File System Recovery:

   • Restore critical application files
   • Recover user data and documents
   • Restore configuration files and settings

Phase 3: Application Recovery (4-8 hours)

1. Service Installation: Install and configure applications
2. Configuration Restoration: Apply application settings and configurations
3. Integration Testing: Verify system integrations and dependencies
4. User Access Testing: Validate authentication and authorization

Phase 4: Validation and Handover (6-12 hours)

1. Functionality Testing: Comprehensive application testing
2. Performance Validation: Verify system performance meets requirements
3. Data Integrity Checks: Validate data consistency and completeness
4. User Acceptance: Obtain user confirmation of system functionality

3. Emergency Recovery Procedures

Rapid Recovery for Critical Systems

• Hot Standby Systems: Immediate failover to redundant systems
• Database Mirroring: Automatic failover to mirror databases
• Virtual Machine Snapshots: Quick restoration from recent snapshots
• Cloud-based Recovery: Restore to cloud infrastructure if needed

Backup Infrastructure

Storage Systems

Primary Backup Storage

• Technology: Enterprise SAN or NAS systems
• Capacity: 500TB with 30% growth capacity
• Performance: 10Gb/s network connectivity
• Redundancy: RAID 6 with hot spare drives

Secondary/Offsite Storage

• Cloud Storage: Azure Backup, AWS S3, or Google Cloud Storage
• Physical Offsite: Secure offsite facility with environmental controls
• Tape Storage: LTO-8 tapes for long-term archival
• Replication: Real-time replication to disaster recovery site

Backup Tools and Software

Enterprise Backup Solutions

• Primary: Veeam Backup & Replication
• Database: Native database backup tools + enterprise solution
