Backup and Recovery
The process of creating copies of data and systems so they can be restored in the event of data loss, corruption, hardware failure, cyberattack, or disaster.
In-Depth Explanation
Backup and recovery encompasses the strategies, tools, and processes for creating data copies and restoring them when needed. It is a critical component of business continuity, protecting against data loss from hardware failure, human error, cyberattacks, and natural disasters.
Backup types:
- Full backup: Complete copy of all data (comprehensive but time-consuming)
- Incremental backup: Only data changed since last backup (faster, less storage)
- Differential backup: All data changed since last full backup (middle ground)
- Continuous/CDP: Continuous Data Protection capturing every change in real time
Backup strategies:
- 3-2-1 rule: 3 copies, 2 different media types, 1 offsite location
- 3-2-1-1-0: Add 1 air-gapped copy and 0 errors (verified backup integrity)
- Grandfather-father-son: Daily, weekly, and monthly backup rotation
- Retention policies: How long backups are kept (30 days, 1 year, 7 years)
Cloud backup solutions:
- AWS: S3, EBS snapshots, AWS Backup
- Azure: Azure Backup, Azure Site Recovery
- Google Cloud: Cloud Storage, persistent disk snapshots
- Third-party: Veeam, Acronis, Commvault, Druva
Recovery objectives:
- RPO (Recovery Point Objective): Maximum acceptable data loss (how recent must the backup be?)
- RTO (Recovery Time Objective): Maximum acceptable downtime (how fast must we recover?)
- Example: RPO of 1 hour means backups every hour; RTO of 4 hours means systems must be restored within 4 hours
Australian data backup considerations:
- Australian Privacy Principles require reasonable security measures including backup
- Consider data sovereignty -- where backup data is stored geographically
- Cloud providers with Australian regions help meet data residency requirements
- ACSC Essential Eight recommends regular backups and tested recovery procedures
Business Context
The average cost of data loss for an Australian mid-market business is $150,000-$500,000 per incident, making robust backup and recovery one of the most important investments a business can make.
How Clever Ops Uses This
Clever Ops implements comprehensive backup and recovery solutions for Australian businesses, configuring automated backup schedules, setting appropriate RPO/RTO targets, and ensuring data sovereignty compliance. We test recovery procedures regularly to verify backups actually work when needed.
Example Use Case
"An Australian professional services firm implements automated daily backups with 4-hour RPO to AWS Sydney region, and tests full recovery quarterly, reducing their data loss risk from days to hours."
