On First Thought....

Quorum Disk
MSCS + Oracle FailSafe: - Active-Active Cluster+ MS Windows 2000 Advanced Server+ Oracle FailSafe
+ Total 400GB Storage Needed (considering the growth)
EMC+ EMC Powerpath (for DMP)+ EMC BCV
+ Total 1TB Physical Storage Needed (BCV Mirroring + additional 10 disk paritions for Quorum Disk )

Unsolved Issues
• Expensive & Proprietary• Unforeseen cost in software
- Advanced Server, FailSafe, Powerpath, BCV
• Cost overhead in hardware also- Double sizing + Mirroring + Quorunm Disk
• Would active-active cluster be okay?• Support issues for Oracle FailSafe• Will cluster be reliable?• Very lengthy recovery process needed for cluster failure• What about backup?• Do we have disaster recovery plan?

Trends in Data Protection• Annual data growth is 100-400%
• Over half of all data resides in databases• Not just more data…more files
• What backup window?• 24 by forever applications• Downtime means lost revenue - or worse
• Greater emphasis on disaster recovery• Need enforceable offsite procedures
• Staffing can’t keep up• Need centralized control for consistency• Interfaces must be intuitive and foolproof

Backup... Common Bad Practices
• Zero possibility of failure “until you face it”• Not my responsibility “until boss asks for it.”• Our developers knows what they do• Backup software costs money• Backup software costs resource• Over-confidence in RAID protection• Local disk backup is just okay• Viruses harm only desktops, not servers• DR? not my story

Why buy commercialbackup software?
• Complete network-wide protection, including system information and registry
• Online backup for applications• Minimized administration cost with centralized &
automated backup• Open File Backup• Backup Strategy (including Disaster Recovery)• And many other reasons...
