Causes of Data Loss

THE BACKUP IMPERATIVE

(5)

What is Backup?

DATA LOSS AND BACKUP

Backup & Restore



Establish “Restore Points”



Sync is “NOT” Backup

Backup Benefits



Recovery to specific time selected



Automated Compliant Process



Protection against failure, human error or natural disaster

Backup & Restore Options



Tape or Disk



Hourly, Daily, Weekly, Monthly, Quarterly, Yearly



On-site, Off-site, Private, Public

The Language of Backup & Recovery

DATA LOSS AND BACKUP

Frequent Restore Points



Restore Point Objectives (RPO) to minimize data loss

today -1 -2 -7 -14 -30 -60 -365

Rapid Restore Time



Restore Time Objectives (RTO) to minimize down-time

+4 +3 +2 +1 +0.5 +0.1 0

Step 1

Perform backup to Public or Private Cloud

(Slow backups / restores, but safe data)

Hybrid Business Cloud Backup

DEFINITION:

Replicate backups to cloud

(Safe-keeping of data)

Move media by truck



Backup directly from agent



Replicate from local server

Cost Variables

Transport Via Encrypted Portable Disks

REPLICATING LARGE BACKUP SETS

Seeding and Feeding



“Seed” initial backup into the cloud



“Feed” an existing cloud backup

Portable disks complement WAN transport



10TB disk array delivers 1Gbps



Export and import backup sets

Security and compression



Transport should always be encrypted

(14)

Typical Hybrid Business Cloud Deployment

REPLICATE WITH BOTH PORTABLE DISKS AND WAN

Private vs. Public Cloud Targets

Pros

Cons

Private Cloud

(Owned

storage)

• More secure

• Less expensive

• Requires partner or expertise

• Up-front investment in hardware

Pros

Cons

Private Cloud

(Owned storage)

• More secure

• Less expensive

• Requires partner or expertise

• Up-front investment in hardware

Public Cloud

(Hosted storage)

• Lower investment

• Easily expansible

• Less secure & more expensive

Disaster Recovery Options

HYBRID BUSINESS CLOUD RECOVERY

Restore via big pipe … to servers in cloud

Restore via portable media … to LAN

Hybrid Business Cloud Backup

SUMMARY

Alternatives to Tape



Can be automated



Less expensive for small data volumes



Max Data-Protection Limit Imposed by nightly replication

Costs of Hybrid Business Cloud



Fixed costs: Very low



Variable costs: Bandwidth & target disk
