How do you ensure a backup is anonymized?

To ensure that a backup is anonymized, the key factor is to manage the exposure of any identifiable information contained within that backup. One effective method to achieve this is by not sending or sharing the dictionary file that may map user identifiers or sensitive data. Keeping the dictionary file on-site minimizes the risk that such identifiable information could be exposed or accessed by unauthorized parties, as it limits its availability to only those who are within the secure environment where the backup was created.

While encryption, access limitations, and storage location are important considerations for data security, they do not specifically address the issue of anonymization as directly as controlling the distribution of potentially sensitive mapping files. Encryption secures data in transit or at rest but does not inherently make the data untraceable or anonymous. Limiting access is crucial for security but has no impact on whether the data is anonymized itself. Storing backups in a different location can help with data redundancy and disaster recovery but again does not necessarily anonymize the data contained in those backups.
