On-site Backup
An On-site Backup is a backup strategy where data copies are stored within the same physical location as the original data, typically on local storage systems such as external hard drives, tape libraries, or local backup servers. This approach provides quick access to backup data but carries risks related to location-specific disasters.
Key Characteristics
- Local Storage: Backup data stored within the same facility as original data
- Fast Access: Quick retrieval and restoration of backup data
- Direct Connection: Typically uses local network connections
- Physical Proximity: Same location as primary data systems
Advantages
- Rapid Recovery: Fastest possible restore times due to local access
- Low Bandwidth Usage: No network bandwidth required for backup/restore
- Cost Effective: Lower ongoing costs compared to cloud solutions
- Full Control: Complete control over backup infrastructure
- High Performance: Fast backup and restore operations
Disadvantages
- Disaster Vulnerability: Susceptible to the same location-specific risks as primary data
- Limited Protection: No protection against site-wide disasters
- Physical Security: Requires local physical security measures
- Maintenance: Requires local infrastructure maintenance
- Space Requirements: Needs physical space within the facility
Best Practices
- Combine with offsite backup strategies for comprehensive protection
- Implement proper environmental controls for backup storage
- Regular testing of backup integrity and restoration processes
- Secure physical access to backup systems
- Monitor backup system health and capacity
Use Cases
- Quick recovery of recently lost data
- High-frequency backup requirements
- Large data volumes where network transfer is impractical
- Temporary backup before offsite transfer
