2019/08/05 - AWS DataSync - 3 updated api methods
Changes Support VPC endpoints.
{'SecurityGroupArns': ['string'],
'SubnetArns': ['string'],
'VpcEndpointId': 'string'}
Activates an AWS DataSync agent that you have deployed on your host. The activation process associates your agent with your account. In the activation process, you specify information such as the AWS Region that you want to activate the agent in. You activate the agent in the AWS Region where your target locations (in Amazon S3 or Amazon EFS) reside. Your tasks are created in this AWS Region.
You can activate the agent in a VPC (Virtual private Cloud) or provide the agent access to a VPC endpoint so you can run tasks without going over the public Internet.
You can use an agent for more than one location. If a task uses multiple agents, all of them need to have status AVAILABLE for the task to run. If you use multiple agents for a source location, the status of all the agents must be AVAILABLE for the task to run.
Agents are automatically updated by AWS on a regular basis, using a mechanism that ensures minimal interruption to your tasks.

string
[REQUIRED]
Your agent activation key. You can get the activation key either by sending an HTTP GET request with redirects that enable you to get the agent IP address (port 80). Alternatively, you can get it from the AWS DataSync console.
The redirect URL returned in the response provides you the activation key for your agent in the query string parameter activationKey . It might also include other activation-related parameters; however, these are merely defaults. The arguments you pass to this API call determine the actual configuration of your agent.
For more information, see Activating an Agent in the AWS DataSync User Guide.
string
The name you configured for your agent. This value is a text reference that is used to identify the agent in the console.
list
The key-value pair that represents the tag that you want to associate with the agent. The value can be an empty string. This value helps you manage, filter, and search for your agents.
Note
Valid characters for key and value are letters, spaces, and numbers representable in UTF-8 format, and the following special characters: + - = . _ : / @.
(dict) --
Represents a single entry in a list of AWS resource tags. TagListEntry returns an array that contains a list of tasks when the ListTagsForResource operation is called.
Key (string) -- [REQUIRED]
The key for an AWS resource tag.
Value (string) --
The value for an AWS resource tag.
string
The ID of the VPC (Virtual Private Cloud) endpoint that the agent has access to. This is the client-side VPC endpoint, also called a PrivateLink. If you don't have a PrivateLink VPC endpoint, see Creating a VPC Endpoint Service Configuration in the AWS VPC User Guide.
VPC endpoint ID looks like this: vpce-01234d5aff67890e1 .
list
The Amazon Resource Names (ARNs) of the subnets in which DataSync will create Elastic Network Interfaces (ENIs) for each data transfer task. The agent that runs a task must be private. When you start a task that is associated with an agent created in a VPC, or one that has access to an IP address in a VPC, then the task is also private. In this case, DataSync creates four ENIs for each task in your subnet. For a data transfer to work, the agent must be able to route to all these four ENIs.

list
The ARNs of the security groups used to protect your data transfer task subnets. See CreateAgentRequest$SubnetArns.

(string) --
Options (dict) --
The set of configuration options that control the behavior of a single execution of the task that occurs when you call StartTaskExecution . You can configure these options to preserve metadata such as user ID (UID) and group (GID), file permissions, data integrity verification, and so on.
For each individual task execution, you can override these options by specifying the overriding OverrideOptions value to operation.
VerifyMode (string) --
A value that determines whether a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred.
Default value: POINT_IN_TIME_CONSISTENT.
POINT_IN_TIME_CONSISTENT: Perform verification (recommended).
NONE: Skip verification.
Atime (string) --
A file metadata value that shows the last time a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT, DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING phase). However, Atime 's behavior is not fully standard across platforms, so AWS DataSync can only do this on a best-effort basis.
Default value: BEST_EFFORT.
BEST_EFFORT: Attempt to preserve the per-file Atime value (recommended).
NONE: Ignore Atime .
Note
If Atime is set to BEST_EFFORT, Mtime must be set to PRESERVE.
If Atime is set to NONE, Mtime must also be NONE.
Mtime (string) --
A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase.
Default value: PRESERVE.
PRESERVE: Preserve original Mtime (recommended)
NONE: Ignore Mtime .
Note
If Mtime is set to PRESERVE, Atime must be set to BEST_EFFORT.
If Mtime is set to NONE, Atime must also be set to NONE.
Uid (string) --
The user ID (UID) of the file's owner.
Default value: INT_VALUE. This preserves the integer value of the ID.
INT_VALUE: Preserve the integer value of UID and group ID (GID) (recommended).
NONE: Ignore UID and GID.
Gid (string) --
The group ID (GID) of the file's owners.
Default value: INT_VALUE. This preserves the integer value of the ID.
INT_VALUE: Preserve the integer value of user ID (UID) and GID (recommended).
NONE: Ignore UID and GID.
PreserveDeletedFiles (string) --
A value that specifies whether files in the destination that don't exist in the source file system should be preserved.
Default value: PRESERVE.
PRESERVE: Ignore such destination files (recommended).
REMOVE: Delete destination files that aren’t present in the source.
PreserveDevices (string) --
A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and recreate the files with that device name and metadata on the destination.
Note
AWS DataSync can't sync the actual contents of such devices, because they are nonterminal and don't return an end-of-file (EOF) marker.
Default value: NONE.
NONE: Ignore special devices (recommended).
PRESERVE: Preserve character and block device metadata. This option isn't currently supported for Amazon EFS.
PosixPermissions (string) --
A value that determines which users or groups can access a file for a specific purpose such as reading, writing, or execution of the file.
Default value: PRESERVE.
PRESERVE: Preserve POSIX-style permissions (recommended).
NONE: Ignore permissions.
Note
AWS DataSync can preserve extant permissions of a source location.
BytesPerSecond (integer) --
A value that limits the bandwidth used by AWS DataSync. For example, if you want AWS DataSync to use a maximum of 1 MB, set this value to 1048576 ( =1024*1024 ).
Excludes (list) --
A list of filter rules that determines which files to exclude from a task. The list should contain a single filter string that consists of the patterns to exclude. The patterns are delimited by "|" (that is, a pipe), for example: "/folder1|/folder2"
(dict) --
Specifies which files, folders and objects to include or exclude when transferring files from source to destination.
FilterType (string) --
The type of filter rule to apply. AWS DataSync only supports the SIMPLE_PATTERN rule type.
Value (string) --
A single filter string that consists of the patterns to include or exclude. The patterns are delimited by "|" (that is, a pipe), for example: /folder1|/folder2
ErrorCode (string) --
Errors that AWS DataSync encountered during execution of the task. You can use this error code to help troubleshoot issues.
