Definição de Continuidade de Negócios
Disaster Recovery
Como voltar a normalidade de
forma rápida após um desastre?
Alta Disponibilidade
Como previnir e minimizar o downtime?
Proteção de Dados
Como gartantir que dados importantes não se percam?
Continuidade deNegócios
Como manter o negócio rodando
Vamos a Norma – BS25999
Continuidade de Negócios: Visão Macro
Expectativa de Disponibilidade Continua aumentando
• RTO’s diminuindo de>24 horas para <12 horas
Custo do downtime continua Crescendo
• Aumento da dependendica da infraestrutura x86
Continuidade de Negócios = Reduzir “Downtime”

Desafios em Implementar a Continuidade de Negócios
Custo
• Hardware adicional; identico 1:1
• Ferramentas e Treinamentos Adicionais
Complexidade
• Gerenciamento e Provisionamento
• Necessidades específicas para cada aplicação
Confiabilidde
• Soluções Complexas são difíceis de testar
• Exige treinamento específico da equipe

Backup Tradicional• Disruptivo para aplicação e usuários
• Lento, processo complexo para full restore
• Dependencia de hardware amarra o processo de backup/restore
Backup comVMware vSphere• Não disruptivo
• Permite off-host, off-LAN backup com softwares de backup via vStorage APIs for Data Protection
• Permite babkup em nível de imagem e de arquivos das VMs.

Agent-less, disk-based backup and recovery of your VMs
VM or file level restore
Incremental backups and data de-dupe to save disk space
Quick, simple and complete data protection for your VMs
Centralized Management through VMware Infrastructure client
Cost-effective use of storage for backup data

VMware Data Recovery Key Components
vCenter Server integration- vSphere Client Plugin- Wizard driven backup and restore job creation- Automatically import virtual machine inventory- Awareness of HA/VMotion/DRS- Leverage vCenter licensing engine
VMware vSphere- VSS support via VMware Tools
- Changed block tracking functionality allows backups to be more efficient
Destination Storage- Any VMFS storage: DAS, NFS, iSCSI or Fibre Channel
storage plus CIFS shares as target
- All backed up virtual machines are stored in a deduplicated datastore
Backup and Recovery Appliance- Linux appliance in OVF format - leverages vStorage
API for Data Protection to discover, manage backup and restore
- First backup is full VM, then incremental forever
- VM or file level restore
VMware vCenter Server
Improved Recovery with VMware Data Recovery
• Backups and restores can run simultaneously
• Highly customizible image level restore
Replace a lost VM
Restore to a different location/datastore
Select disks to restore
• Fast “roll back”:
Use change tracking to roll back a virtual disk/Virtual Machine to an earlier state
Only transfers modified blocks for fast restore
• Restore Rehearsal:
Run a restore of a VM to a different datastore and disable networking

Production
• Most common traditional scenario
• Very expensive architecture
• Leverage recovery infrastructure for test, development, training
• Reduces sunk cost of recovery site
• Production applications at both sites
• Each site acts as the recovery site for the other
• Less common scenario
• Protection against large localized failures in datacenter
Topologias
Padrão
1:1 mapping between each protected site and its recovery site
Shared Recovery Sites:
Multiple sites can be protected by a single, shared recovery site
Leverage for remote office/branch office topologies
