Backup and Disaster recovery

Why do we backup data ?

• minimize time to recover
• minimize data loss
• balance cost with liability

How looks the traditional backup ?

• expensive
• time consuming
• high capex
• high opex
• only big companies can afford it
• requires department, processes, very complex

The best way to modernize the backup architecture is using cloud.

• API driven
• simple , secure and durable
• variable cost

Immediate cloud backup benefits :

Typical cloud service is AWS S3 and AWS S3 Glacier  designed for 99,999999999% durability.

Backup patterns :

File gateway 

Use cases : 

• back up on-premises data to the cloud
• hybrid cloud workflows
• low-latency on-premises access to cloud storage
• content distribution and collaboration

tape gateway

volume gateway

For the AWS computing :

EBS Snapshots

 

Amazon EFS Snapshots for databases

Cloud service for backup : AWS Backup : centralize compliance, automate backup, work across services.

Disaster Recovery

• natural disasters
• infrastructure availabilit and access
• rogue actors

Estimate is that only 49% organizations would be unlikely to survive if hit by a disaster.

Modernizing DR using cloud

• API driven
• Low overhead
• variable cost

Disaster in the cloud benefits :

• no upfront hardware investment needed
• only pay for rightsized compute/storage when needed
• lower it mgmt
• more automation
• easy and repeatable testing
• systems up in minutes

Conclusion

Using the cloud for backup and disaster recovery provides benefits and lower cost and immediate use. Provides value for organization to secure their digital assets.
