This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::ElastiCache::Snapshot object:

  $service_obj->Method(Att1 => { AutomaticFailover => $value, ..., VpcId => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::ElastiCache::Snapshot object:

  $result = $service_obj->Method(...);


Represents a copy of an entire Redis cluster as of the time when the snapshot was taken.


AutomaticFailover => Str

  Indicates the status of Multi-AZ with automatic failover for the source
Redis replication group.

Amazon ElastiCache for Redis does not support Multi-AZ with automatic failover on:

  • Redis versions earlier than 2.8.6.

  • Redis (cluster mode disabled): T1 and T2 cache node types.

  • Redis (cluster mode enabled): T1 node types.

AutoMinorVersionUpgrade => Bool

  This parameter is currently disabled.

CacheClusterCreateTime => Str

  The date and time when the source cluster was created.

CacheClusterId => Str

  The user-supplied identifier of the source cluster.

CacheNodeType => Str

  The name of the compute and memory capacity node type for the source

The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts.

  • General purpose:

    • Current generation:

      T2 node types: cache.t2.micro, cache.t2.small, cache.t2.medium

      M3 node types: cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge

      M4 node types: cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge

    • Previous generation: (not recommended)

      T1 node types: cache.t1.micro

      M1 node types: cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge

  • Compute optimized:

    • Previous generation: (not recommended)

      C1 node types: cache.c1.xlarge

  • Memory optimized:

    • Current generation:

      R3 node types: cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

      R4 node types; cache.r4.large, cache.r4.xlarge, cache.r4.2xlarge, cache.r4.4xlarge, cache.r4.8xlarge, cache.r4.16xlarge

    • Previous generation: (not recommended)

      M2 node types: cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge


  • All T2 instances are created in an Amazon Virtual Private Cloud (Amazon VPC).

  • Redis (cluster mode disabled): Redis backup/restore is not supported on T1 and T2 instances.

  • Redis (cluster mode enabled): Backup/restore is not supported on T1 instances.

  • Redis Append-only files (AOF) functionality is not supported for T1 or T2 instances.

For a complete listing of node types and specifications, see:

  • Amazon ElastiCache Product Features and Details (

  • Cache Node Type-Specific Parameters for Memcached (

  • Cache Node Type-Specific Parameters for Redis (

CacheParameterGroupName => Str

  The cache parameter group that is associated with the source cluster.

CacheSubnetGroupName => Str

  The name of the cache subnet group associated with the source cluster.

Engine => Str

  The name of the cache engine (C<memcached> or C<redis>) used by the
source cluster.

EngineVersion => Str

  The version of the cache engine version that is used by the source

NodeSnapshots => ArrayRef[Paws::ElastiCache::NodeSnapshot]

  A list of the cache nodes in the source cluster.

NumCacheNodes => Int

  The number of cache nodes in the source cluster.

For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.

NumNodeGroups => Int

  The number of node groups (shards) in this snapshot. When restoring
from a snapshot, the number of node groups (shards) in the snapshot and
in the restored replication group must be the same.

Port => Int

  The port number used by each cache nodes in the source cluster.

PreferredAvailabilityZone => Str

  The name of the Availability Zone in which the source cluster is

PreferredMaintenanceWindow => Str

  Specifies the weekly time range during which maintenance on the cluster
is performed. It is specified as a range in the format
ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window
is a 60 minute period.

Valid values for ddd are:

  • sun

  • mon

  • tue

  • wed

  • thu

  • fri

  • sat

Example: sun:23:00-mon:01:30

ReplicationGroupDescription => Str

  A description of the source replication group.

ReplicationGroupId => Str

  The unique identifier of the source replication group.

SnapshotName => Str

  The name of a snapshot. For an automatic snapshot, the name is
system-generated. For a manual snapshot, this is the user-provided

SnapshotRetentionLimit => Int

  For an automatic snapshot, the number of days for which ElastiCache
retains the snapshot before deleting it.

For manual snapshots, this field reflects the SnapshotRetentionLimit for the source cluster when the snapshot was created. This field is otherwise ignored: Manual snapshots do not expire, and can only be deleted using the DeleteSnapshot operation.

Important If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.

SnapshotSource => Str

  Indicates whether the snapshot is from an automatic backup
(C<automated>) or was created manually (C<manual>).

SnapshotStatus => Str

  The status of the snapshot. Valid values: C<creating> | C<available> |
C<restoring> | C<copying> | C<deleting>.

SnapshotWindow => Str

  The daily time range during which ElastiCache takes daily snapshots of
the source cluster.

TopicArn => Str

  The Amazon Resource Name (ARN) for the topic used by the source cluster
for publishing notifications.

VpcId => Str

  The Amazon Virtual Private Cloud identifier (VPC ID) of the cache
subnet group for the source cluster.
