Specifies whether automatic backups are enabled on the file system that you are creating.
Set the value to true to enable automatic backups. If you are creating a file
system that uses One Zone storage classes, automatic backups are enabled by default. For more
information, see Automatic backups in the
Amazon EFS User Guide.
Default is false. However, if you specify an AvailabilityZoneName,
the default is true.
Backup is not available in all Amazon Web Services Regions where Amazon EFS is available.
A string of up to 64 ASCII characters. Amazon EFS uses this to ensure idempotent creation.
A Boolean value that, if true, creates an encrypted file system. When creating an
encrypted file system, you have the option of specifying an existing Key Management Service key (KMS key).
If you don't specify a KMS key, then the default KMS key for
Amazon EFS, /aws/elasticfilesystem, is used to protect the encrypted file system.
The ID of the KMS key that you want to use to protect the encrypted file system. This parameter is required only if you want to use a non-default KMS key. If this parameter is not specified, the default KMS key for Amazon EFS is used. You can specify a KMS key ID using the following formats:
Key ID - A unique identifier of the key, for example
1234abcd-12ab-34cd-56ef-1234567890ab.
ARN - An Amazon Resource Name (ARN) for the key, for example
arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab.
Key alias - A previously created display name for a key, for example
alias/projectKey1.
Key alias ARN - An ARN for a key alias, for example
arn:aws:kms:us-west-2:444455556666:alias/projectKey1.
If you use KmsKeyId, you must set the CreateFileSystemRequest$Encrypted
parameter to true.
EFS accepts only symmetric KMS keys. You cannot use asymmetric KMS keys with Amazon EFS file systems.
The performance mode of the file system. We recommend generalPurpose
performance mode for most file systems. File systems using the maxIO performance
mode can scale to higher levels of aggregate throughput and operations per second with a
tradeoff of slightly higher latencies for most file operations. The performance mode
can't be changed after the file system has been created.
The maxIO mode is not supported on file systems using One Zone storage classes.
The throughput, measured in
MiB/s,
that you want to provision for a file system that you're creating. Valid values are
1-1024. Required if ThroughputMode is set to provisioned. The upper
limit for throughput is 1024 MiB/s. To increase this limit, contact Amazon Web Services Support. For
more information, see Amazon EFS quotas that you can increase in the Amazon EFS User Guide.
Use to create one or more tags associated with the file system. Each
tag is a user-defined key-value pair. Name your file system on creation by including a
"Key":"Name","Value":"{value}" key-value pair. Each key must be unique. For more
information, see Tagging Amazon Web Services resources
in the Amazon Web Services General Reference Guide.
Specifies the throughput mode for the file system. The mode can be bursting,
provisioned, or elastic. If you set ThroughputMode to
provisioned, you must also set a value for
ProvisionedThroughputInMibps. After you create the file system, you can
decrease your file system's throughput in Provisioned Throughput mode or change between
the throughput modes, with certain time restrictions. For more information, see Specifying
throughput with provisioned mode in the Amazon EFS User
Guide.
Default is bursting.
Used to create a file system that uses One Zone storage classes. It specifies the Amazon Web Services Availability Zone in which to create the file system. Use the format
us-east-1ato specify the Availability Zone. For more information about One Zone storage classes, see Using EFS storage classes in the Amazon EFS User Guide.One Zone storage classes are not available in all Availability Zones in Amazon Web Services Regions where Amazon EFS is available.
