1. Tape Device Compatibility and Support:

• Legacy System Integration: While DPX supports SCSI-2 and leading tape devices, some legacy systems might require specialized configurations or adjustments.
• Changing Hardware Standards: Organizations using outdated or unique tape formats may still face challenges in ensuring smooth integration with newer LTO-9 technology.
• Device Configuration Complexity: Managing multiple types of tape devices and media changers could require additional training for IT staff to handle specific setups.

2. Streamlined Tape Management:

• Complex Workflows: Managing both Virtual Tape Libraries (VTLs) and traditional tape libraries simultaneously might create complex workflows that require careful coordination and planning.
• Vendor Discontinuation: Systems no longer supported by vendors could pose maintenance challenges, requiring in-depth troubleshooting or workarounds.

3. Robust Backup and Recovery Capabilities:

• Backup Infrastructure Optimization: Reducing backup time and impact by up to 90% can be beneficial, but achieving this may require specific network and storage optimizations.
• Replication Coordination: Point-to-point replication is valuable, but organizations must ensure bandwidth and latency are optimized to support disaster recovery and remote office requirements.

4. Immutable and Secure Backups:

• Management of Air-Gapped Copies: Creating and storing immutable snapshots on tape or in the cloud demands additional management processes to track and monitor offline copies.
• Compliance Requirements: Ensuring immutable backups align with regulatory requirements could require extra steps to verify their integrity.

5. Cost-Effective NDMP Backups:

• Network Overhead: Although NDMP backups are cost-effective, they might increase network overhead if not properly managed.
• Vendor-Specific Dependencies: Some NDMP backup features may rely heavily on specific storage vendors, potentially limiting flexibility if the organization shifts to other storage platforms.
