Why Protect Your Data?• Protect against accidental corruption or

loss of data Human or program errors System failures (hardware, software,

network)

• Protect against malicious corruption or loss of data Viruses, Sabotage

• Protect against local and wide area disasters Disaster Recovery/Business

Continuance

• Because you have to! HIPAA, Sarbanes-Oxley,

SEC 17 A, EU DPA, etc.

No longer an option!

Interesting Points to Consider

• On average, companies value 100 megabytes of data at more than $1 million (Source: Ontrack Data International)

• Estimates show that 1 out of 500 data centers will have a severe disaster each year

• 93% of companies that lost their data center for 10 days or more due to a disaster filed for bankruptcy within one year of the disaster. 50% of businesses that found themselves without data management for this same time period filed for bankruptcy immediately. (Source: National Archives & Records Administration in Washington.)

Key Considerations

• Recovery Point Objective (RPO) How much data can you afford to lose?

• Recovery Time Objective (RTO) How long can you afford to be without

your data? What are downtime costs? What are downtime implications?

• Data Classification How critical is your data to the

operational and financial viability of the company?

All data is not created equal

• Budget How much money can you afford to

spend? Source: Enterprise Storage Group“The Evolution of Data Protection”

RTO vs. RPO vs. Budget $ trade-offsas one size does not fit all…

Data Protection Strategies

• Traditional Tape Backup Nightly backup to tape

Full backup on weekends Incremental or differential

on weekdays

RPO = up to 24 hours

• Snapshots Snapshot taken every 2 hours

RPO = up to 2 hours

Risk Mitigation

Page 12

Reducing Data Loss (RPO)

• Traditional Tape Backup 1. File share taken offline at 12:00 am

2. Backed up to tape

3. File share brought back online at 12:30 am

4. Corruption occurs at 4:30 pm

5. Previous night’s tape located

6. File share restored from previous night’s backup tape

7. File share back online at 6:00 pm

16 hours of work is lost!

• Snapshots1. Snapshot of File Share taken every

2 hours 12 am, 2 am, 4 am, 6 am, 8 am, 10 am,

12 pm, 2 pm, 4 pm, 6 pm, etc.

2. Corruption occurs at 4:30 pm

3. File share restored from 4:00 pm snapshot

4. File share back online at 4:45 pm

30 minutes of work is lost!

Improving Recovery Time (RTO)

• Traditional Tape Backup 1. File share taken offline at 12:00 am

2. Backed up to tape

3. File share brought back online at 12:30 am

4. Corruption occurs at 4:30 pm

5. Previous night’s tape located

6. File share restored from previous night’s backup tape

7. File share back online at 6:00 pm

Data unavailable for 1 ½ hours!

• Snapshots1. Snapshot of File Share taken every 2

hours 12 am, 2 am, 4 am, 6 am, 8 am, 10 am,

12 pm, 2 pm, 4 pm, 6 pm, etc.

2. Corruption occurs at 4:30 pm

3. File share restored from 4:00 pm snapshot

4. File share back online at 4:45 pm

Data unavailable for 15 minutes!
