[AWS Resource Reference](https://docs.arpio.io/aws-reference-guides?hsLang=en#aws-resource-reference) # Amazon ElastiCache ## ElastiCache resource replication with Arpio Arpio supports replication of Amazon ElastiCache infrastructure into your recovery environment. Redis, Memcached, and Valkey ElastiCache nodes are supported. Arpio treats ElastiCache nodes as an ephemeral cache, and therefore does not replicate the data that is stored within these systems. Arpio provisions the following resource types from Amazon ElastiCache. #### Cache Cluster Arpio replicates ElastiCache cache clusters to the recovery environment. The complete topology of the cache cluster is replicated. Resources are only active during a test or an actual failover to minimize AWS expense. The following resources are automatically selected into recovery points when a cache cluster is selected: - The ElastiCache Parameter Group associated with the cache cluster - The ElastiCache Subnet Group associated with the cache cluster - The security groups associated with the cache cluster #### Replication Group Arpio clones ElastiCache replication groups to the recovery environment. The complete topology of the replication group is cloned. Resources are only active during a test or an actual failover to minimize AWS expense. The following resources are automatically selected into recovery points when a replication group is selected: - The ElastiCache cache clusters included in the replication group - User groups that are associated with the replication group #### Parameter Group Arpio copies ElastiCache parameter groups to the recovery environment. Parameter groups are copied identically, as no translation is needed in the recovery environment. #### Subnet Group Arpio copies ElastiCache subnet groups to the recovery environment. The subnet IDs and the VPC ID are translated to match the IDs of the cloned subnets and VPC in the recovery environment. #### User Arpio copies ElastiCache users to the recovery environment. Arpio is unable to read password values from users in the primary environment, so for users that have authentication type "password" configured, Arpio will generate a random password for them in the recovery environment. #### User Group Arpio copies ElastiCache user groups to the recovery environment and associates them with the corresponding replication groups that they were associated to within the primary environment. ### Redis AUTH Token If your ElastiCache is configured for Redis, then you have already configured a [Redis AUTH token](https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/auth.html) or password in your source cluster.  Because Arpio cannot read this token, you must configure a specific [Secrets Manager](https://docs.aws.amazon.com/secretsmanager/latest/userguide/intro.html) secret containing the appropriate token to your recovery environment after you add the cluster to your Arpio application.  Arpio will notify you when it's time to create this Secret and tell you the expected name of the recovery Secret via Arpio issue message. This secret must be configured as a plaintext string in Secrets Manager. - [Getting Started](https://docs.arpio.io/getting-started?hsLang=en#main-content) - [New Account Setup](https://docs.arpio.io/getting-started?hsLang=en#new-account-setup) - [New Application Setup](https://docs.arpio.io/getting-started?hsLang=en#new-application-setup) - [Arpio Fundamentals](https://docs.arpio.io/arpio-fundamentals?hsLang=en#main-content) - [Platform Fundamentals](https://docs.arpio.io/arpio-fundamentals?hsLang=en#platform-fundamentals) - [Platform Features](https://docs.arpio.io/arpio-fundamentals?hsLang=en#platform-features) - [Arpio Reference Guides](https://docs.arpio.io/arpio-reference-guides?hsLang=en#main-content) - [Arpio API](https://docs.arpio.io/arpio-reference-guides?hsLang=en#arpio-api) - [Lifecycle Events](https://docs.arpio.io/arpio-reference-guides?hsLang=en#lifecycle-events) - [Role-Based Access Controls (RBAC)](https://docs.arpio.io/arpio-reference-guides?hsLang=en#role-based-access-controls-rbac) - [Single Sign-On (SSO) Integration](https://docs.arpio.io/arpio-reference-guides?hsLang=en#single-sign-on-sso-integration) - [Test Planning](https://docs.arpio.io/arpio-reference-guides?hsLang=en#test-planning) - [Test & Recovery How-To](https://docs.arpio.io/arpio-reference-guides?hsLang=en#test-recovery-how-to) - [AWS Reference Guides](https://docs.arpio.io/aws-reference-guides?hsLang=en#main-content) - [AWS Resource Reference](https://docs.arpio.io/aws-reference-guides?hsLang=en#aws-resource-reference) - [AWS Configuration Tags](https://docs.arpio.io/aws-reference-guides?hsLang=en#aws-configuration-tags) - [AWS Access](https://docs.arpio.io/aws-reference-guides?hsLang=en#aws-access) - [AWS Testing](https://docs.arpio.io/aws-reference-guides?hsLang=en#aws-testing) - [AWS Solutions](https://docs.arpio.io/aws-reference-guides?hsLang=en#aws-solutions) - [Azure Reference Guides](https://docs.arpio.io/azure-reference-guides?hsLang=en#main-content) - [Azure Resource Reference](https://docs.arpio.io/azure-reference-guides?hsLang=en#azure-resource-reference) - [Azure Configuration Tags](https://docs.arpio.io/azure-reference-guides?hsLang=en#azure-configuration-tags) - [Azure Scenarios](https://docs.arpio.io/azure-reference-guides?hsLang=en#azure-scenarios) - [FAQ](https://docs.arpio.io/faq?hsLang=en#main-content) - [AWS FAQ](https://docs.arpio.io/faq?hsLang=en#aws-faq) - [Contact Support](https://docs.arpio.io/faq?hsLang=en#contact-support) - [License & Billing](https://docs.arpio.io/faq?hsLang=en#license-billing) - [Tests and Recoveries](https://docs.arpio.io/faq?hsLang=en#tests-and-recoveries) - Home - Products - Pricing - Blog - Company [![bubble-wand-tight.64](https://docs.arpio.io/hs-fs/hubfs/bubble-wand-tight.64.png?width=64&height=64&name=bubble-wand-tight.64.png "bubble-wand-tight.64")](https://arpio.io) Copyright © 2026, Arpio
