Network Attached Storage: A Superior Alternative to Tape Backup
Overview
Network Attached Storage (NAS) is rapidly becoming the preferred choice over traditional tape backups for efficient and reliable data management and disaster recovery.
The Shift from Tape to NAS
Historically, businesses have relied on tape for data backup due to its cost-effectiveness. However, with decreasing disk storage prices and improved performance, many are reconsidering their options.
Ideal Backup Solution Requirements
1. Cost-Effectiveness: Backups must handle large data volumes economically. Although some data may never be accessed, it must be stored efficiently.
2. Long-Term Reliability: Data may need to be retained for decades. Unlike tape, which can become brittle, disk storage remains stable and accessible over time.
3. Ease of Setup and Operation: As businesses operate longer hours, quick and easy backup processes are essential. Automated backups reduce errors and costs.
4. Efficient Data Restoration: Quick and reliable data recovery is crucial. Tape retrieval can be slow and problematic, especially if tapes degrade. Disk storage offers faster, more straightforward data access.
Advantages of NAS
Network Attached Storage provides a cost-effective and high-performing alternative:
- Speed: Disk-to-disk transfer is faster than writing to tape, speeding up backup times.
- Durability: Disk storage offers greater longevity and reliability than tape.
- Random Access: Disks allow quick access to specific files without the limitations of sequential tape storage.
- Independence: NAS systems operate independently and integrate seamlessly into existing networks.
- Data Optimization: Disk-based systems support tape rotation schemes and can reduce storage needs by eliminating duplicates.
- Offsite Flexibility: Removable drives can serve as affordable offsite storage, while remote NAS systems enable automated backups and immediate recovery solutions.
Implementing NAS
Many companies adopt a staged NAS approach:
1. Onsite Backup: A local NAS provides fast backups for immediate data recovery.
2. Remote Replication: Data is automatically duplicated to an offsite NAS, ensuring business continuity in case of a disaster. Critical data can be mirrored for minimal loss.
Additional NAS Benefits
- Centralized Storage: Simplifies backups compared to managing data on multiple user systems.
- Workgroup Collaboration: Ideal for shared departmental data repositories.
- Regulatory Compliance: Meets requirements for email retention and other regulations like HIPAA and Sarbanes-Oxley.
Conclusion
Even if tape backups aren't entirely phased out, NAS can serve as a rapid staging server, facilitating efficient disk-to-disk-to-tape workflows. Network Attached Storage is quickly establishing itself as the preferred solution for data sharing, management, and backup in enterprise environments.
