Restoring from a backup into a new cache

You can restore an existing backup from Valkey into a new Valkey cache or self-designed cluster, and restore an existing Redis OSS backup into a new Redis OSS cache or self-designed cluster. You can also restore an existing Memcached serverless cache bacup into a new Memcached serverless cache.

Restoring a backup into a serverless cache (Console)

Note

ElastiCache Serverless supports RDB files compatible with Valkey 7.2 and above, and Redis OSS versions between 5.0 and the latest version available.

To restore a backup to a serverless cache (console)

1. Sign in to the AWS Management Console and open the ElastiCache console at https://console.aws.amazon.com/elasticache/.

2. From the navigation pane, choose Backups.

3. In the list of backups, choose the box to the left of the backup name that you want to restore.

4. Choose Actions and then Restore.

5. Enter a name for the new serverless cache, and an optional description.

6. Click Create to create your new cache and import data from your backup.

Restoring a backup into a self-designed cluster (Console)

To restore a backup to a self-designed cluster (console)

1. Sign in to the AWS Management Console and open the ElastiCache console at https://console.aws.amazon.com/elasticache/.

2. From the navigation pane, choose Backups.

3. In the list of backups, choose the box to the left of the backup name you want to restore from.

4. Choose Actions and then Restore.

5. Choose Design your own cache and customize the cluster settings, such as node type, sizes, number of shards, replicas, AZ placement, and security settings.

6. Choose Create to create your new self-designed cache and import data from your backup.

Restoring a backup into a serverless cache (AWS CLI)

Note

ElastiCache Serverless supports RDB files compatible with Valkey 7.2 and above, and Redis OSS versions between 5.0 and the latest version available.

To restore a backup to a new serverless cache (AWS CLI)

The following AWS CLI example creates a new cache using create-serverless-cache and imports data from a backup.

For Linux, macOS, or Unix:

aws elasticache create-serverless-cache \

    --serverless-cache-name CacheName \
    --engine redis
    --snapshot-arns-to-restore Snapshot-ARN 

For Windows:

aws elasticache create-serverless-cache ^

    --serverless-cache-name CacheName ^
    --engine redis ^
    --snapshot-arns-to-restore Snapshot-ARN

Restoring a backup into a self-designed cluster (AWS CLI)

To restore a backup to a self-designed cluster (AWS CLI)

You can restore a Valkey or Redis OSS (cluster mode disabled) backup in two ways.

• aws elasticache create-serverless-cache \
      --serverless-cache-name CacheName \
      --engine redis
      --snapshot-arns-to-restore Snapshot-ARN 

• For Windows:

  aws elasticache create-serverless-cache ^
      --serverless-cache-name CacheName ^
      --engine redis ^
      --snapshot-arns-to-restore Snapshot-ARN

Restoring a backup into a self-designed cluster (AWS CLI)

To restore a backup to a self-designed cluster (AWS CLI)

You can restore a Valkey or Redis OSS serverless cache backup, and you can also restore a Valkey or Redis OSS self-designed cluster.

You can restore a Valkey or Redis OSS serverless cache backup in two ways.

• You can restore to a single-node Valkey or Redis OSS (cluster mode disabled) cluster using the AWS CLI operation create-cache-cluster.

• You can restore to a Valkey or Redis OSS cluster with read replicas (a replication group). To do this, you can use either Valkey or Redis OSS (cluster mode disabled) or Valkey or Redis OSS (cluster mode enabled) with the AWS CLI operation create-replication-group. In this case, you seed the restore with a Valkey or Redis OSS .rdb file. For more information on seeding a new self-designed cluster, see Tutorial: Seeding a new self-designed cluster with an externally created backup.

You can restore a Valkey or Redis OSS (cluster mode disabled) backup in two ways.

To do this, you can use either Valkey or Redis OSS (cluster mode disabled) or Valkey or Redis OSS (cluster mode enabled) with the AWS CLI operation create-replication-group. In this case, you seed the restore with a Valkey or Redis OSS .rdb file. For more information on seeding a new self-designed cluster, see Tutorial: Seeding a new self-designed cluster with an externally created backup.

When using either the create-cache-cluster or create-replication-group operation, be sure to include the parameter --snapshot-name or --snapshot-arns to seed the new cluster or replication group with the data from the backup.
