BB903A Use Case
Accelerated Virtualization Backup for Enterprise Data Centers
Scenario: A mid-sized enterprise running 300+ VMware and Hyper-V VMs needs rapid daily backups without impacting production. Implementation: Integrate the BB903A-HP StoreOnce 4900 60TB Backup System with Veeam or Veritas to capture full and incremental VM images in under two hours. Benefits: Achieves 60% faster backup windows, reduces on-disk data footprint by up to 10× through inline deduplication, and enables sub-30-minute restores to meet strict RTOs.
Regulatory Compliance & Secure Retention for Financial Services
Scenario: A regional bank must archive transaction logs, customer records and audit trails under SEC, FINRA and GDPR regulations. Implementation: Deploy BB903A-HP StoreOnce 4900 with encrypted, WORM-enabled retention vaults and automated retention policies via HP Data Protector. Benefits: Guarantees tamper-proof retention for up to 10 years, automates compliance reporting, reduces audit preparation time by 40%, and ensures data integrity with AES-256 encryption at rest.
Branch Office Data Protection with Deduplicated Replication
Scenario: A global retailer with 50 remote stores needs efficient offsite backup without saturating WAN links. Implementation: Install an HP StoreOnce 4900 at each branch to deduplicate and replicate only changed blocks over low-bandwidth links to the corporate DR site. Benefits: Cuts WAN bandwidth usage by 75%, achieves near-continuous data protection with RPO < 15 minutes, and centralizes recovery workflows for faster, cost-effective disaster recovery.
