Cloud Disaster Recovery Strategies 👇

Any DR strategy starts with finalizing:
𝟭. 𝗥𝗧𝗢 (𝗥𝗲𝗰𝗼𝘃𝗲𝗿𝘆 𝗧𝗶𝗺𝗲 𝗢𝗯𝗷𝗲𝗰𝘁𝗶𝘃𝗲):
How much downtime one can accept ?

𝟮. 𝗥𝗣𝗢 (𝗥𝗲𝗰𝗼𝘃𝗲𝗿𝘆 𝗣𝗼𝗶𝗻𝘁 𝗢𝗯𝗷𝗲𝗰𝘁𝗶𝘃𝗲):
How much data loss one can accept ?

Disaster Recovery Strategies:
𝟭. 𝗕𝗮𝗰𝗸𝘂𝗽 𝗮𝗻𝗱 𝗥𝗲𝘀𝘁𝗼𝗿𝗲:
Creating copies of data and systems periodically to be used for recovery in case of a disaster

Typical,
𝘙𝘛𝘖: Several hours to days
𝘙𝘗𝘖: Can vary from several hours to the last successful backup

𝟮. 𝗣𝗶𝗹𝗼𝘁 𝗟𝗶𝗴𝗵𝘁:
Maintaining essential components in a standby state to quickly scale up the infrastructure during a disaster

Typical,
𝘙𝘛𝘖: Mins to a few hours
𝘙𝘗𝘖: How frequently data is synchronized

𝟯. 𝗪𝗮𝗿𝗺 𝗦𝘁𝗮𝗻𝗱𝗯𝘆:
Preparing a partially operational environment with up-to-date data to minimize downtime during recovery

Typical,
𝘙𝘛𝘖: Mins to a few hours
𝘙𝘗𝘖: Within the last few minutes or hours

𝟰. 𝗛𝗼𝘁 𝗦𝗶𝘁𝗲 / 𝗠𝘂𝗹𝘁𝗶 𝗦𝗶𝘁𝗲:
Running a fully redundant, active production environment in parallel with the primary system, ensuring continuous business operations

Typical,
𝘙𝘛𝘖: Near-zero or a few minutes
𝘙𝘗𝘖: Very minimal, often within the last few seconds
