•Próximos Passos

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
