Always have in mind:
Backups are not important ….. only the recoveries
So test your backups by recover the data / system on regular basis – and document that procedure with screenshots. Also have this in mind, when u change or upgrade the systems or backup software.
How to develop a data protection and recovery strategy?
Which factors would simplify this complex task?
Data protection is the ongoing process of ensuring data integrity, ensuring uninterrupted access to stored data, and ensuring that lost data can be recovered with minimal permanent loss and within an acceptable period of time.
Disaster recovery is the planned response —comprised of processes, policies, and procedures—to the unlikely occurrence of a catastrophic application, database or network failure.
3 factors would be evaluated to setup the strategy – RPO/RTO/Costs
RTO:
The acceptable amount of time it can take to recover lost or corrupt data after a failure, also known as the Recovery Time Objective (RTO)
RPO:
The acceptable amount of permanent data loss that can occur as the result of a system failure, also known as the Recovery Point Objective (RPO)
Costs:
The cost to configure the data protection and recovery system to support the desired strategy
In general, the cost to implement a data protection and recovery strategy increases as the RTO and RPO thresholds decrease.
