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”

Reducing Data Loss & Improving Recovery Time

with AssuredSnap

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

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.


3. File share restored from 4:00 pm snapshot


30 minutes of work is lost!

Risk Mitigation: Lost Revenue and Customer Confidence

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


5. Previous night’s tape located

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


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.


3. File share restored from 4:00 pm snapshot


Data unavailable for 15 minutes!

Speed application time-to-deployment for improved productivity and competitive advantage.

• Operational Access to and use of production data without impacting the data integrity of

production applications. Support Rapid Application development strategies

Use production data without effecting production data or impacting the production application.

Test with full production set vs. subset or “made-up” data; current vs. outdated data Run parallel benchmarks Reveal more problems sooner in test rather than in production

Snapshot Reset

• Logical delete of snapshot data followed by a snapshot create

• Re-use same volume attributes (WWN, SN, LUN, etc) for a new snapshot

• How it works:

Application Development & Test

• Two Methods Reset Snapshot Refresh Snapshot

• Snapshot Refresh Leverages the Original/Write Data Preservation function

Both original and modified data preserved Modified data may be deleted to “refresh” the snapshot back to its original

state

Use production data without effecting production data or impacting the production application

AssuredSnap

• R/Evolution AssuredSnap snapshot limits 16 snapshots per system included on 2000 Series, none on 5000 Series (change per OEM agreements) Licensed upgrade for up to 64 snapshots on 2000 Series, 256 on 5000 Series

• Snapshot volume access Mount for read-only or read-write Both original-state and modified data preserved Delete modified data on writable snapshot (i.e., refresh snapshot) Limited to 32 snapshots per volume

• Roll-forward/Roll-back All snapshots (i.e., both newer and older) are preserved even after performing

a rollback operation Rollback to the original or modified snapshot state Roll back or roll forward to a different snapshot if the initial roll-back was not the one

really needed

• Reset snapshot Logical snapshot delete, create; maintains same volume attributes (e.g., WWN, SN, LUN, etc) for the new

snapshot. Supports application snapshot scripting (requires consistency of WWN, SN, LUN, etc.).

e.g., Backup

• Automated snap pool space management (i.e., auto-grow) Policy set in MB/GB increments Triggered off capacity threshold (default = 90%)
