Considerations for managing warm data:

  • Storage efficiency: Usually, warm data is held in cost-effective storage simply because it is unnecessary to use it frequently, but the access must be quick. Moreover, solutions for this type of data storage are less expensive than cold data storage.
  • Security and compliance: Warm data can contain sensitive information. Due to that, ensuring safety is crucial, meaning security audits and compliance checks are necessary to protect data from breaches and unauthorized access.
  • Data lifecycle management: Regular warm data lifecycle reviews are advisable because warm data might lose relevance over time. Hence, these audits are mandatory before transitioning to cold data storage.
