Remediation

This finding is a configuration review, not evidence that Synapse Link or Fabric Mirroring is active. Before migrating, confirm that the account and its API support continuous backup. Review workload eligibility, retention, restore requirements, regional availability, and pricing impact. Migration from periodic to continuous backup is irreversible.

From Azure Portal​

  1. Open the Azure Cosmos DB account.
  2. Select Backup & Restore.
  3. Select Continuous backup.
  4. Choose the available continuous-backup retention option that meets the recovery requirement.
  5. Review the irreversible-change warning, then confirm the migration.

From Azure CLI​

az cosmosdb update \
  --name {{cosmosdb-account-name}} \
  --resource-group {{resource-group-name}} \
  --backup-policy-type Continuous

Verify the change:

az cosmosdb show \
  --name {{cosmosdb-account-name}} \
  --resource-group {{resource-group-name}} \
  --query "backupPolicy.type" \
  --output tsv

The command must return Continuous.
