Bases: CfnResource

A CloudFormation AWS::DataSync::Task.

The AWS::DataSync::Task resource specifies a task. A task is a set of two locations (source and destination) and a set of Options that you use to control the behavior of a task. If you don’t specify Options when you create a task, AWS DataSync populates them with service defaults.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:: target (CfnResource)
Return type:: None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str)
value (Any)

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (Optional[RemovalPolicy])
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:: key (str)
See:
Return type:: Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Bases: object

Represents the options that are available to control the behavior of a StartTaskExecution operation. This behavior includes preserving metadata, such as user ID (UID), group ID (GID), and file permissions; overwriting files in the destination; data integrity verification; and so on.

A task has a set of default options associated with it. If you don’t specify an option in StartTaskExecution , the default value is used. You can override the default options on each task execution by specifying an overriding Options value to StartTaskExecution .

Parameters:

atime (Optional[str]) – A file metadata value that shows the last time that a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT , AWS 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 . .. epigraph:: If Atime is set to BEST_EFFORT , Mtime must be set to PRESERVE . If Atime is set to NONE , Mtime must also be NONE .
bytes_per_second (Union[int, float, None]) – 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).
gid (Optional[str]) – The group ID (GID) of the file’s owners. Default value: INT_VALUE INT_VALUE : Preserve the integer value of the user ID (UID) and group ID (GID) (recommended). NAME : Currently not supported. NONE : Ignore the UID and GID.
log_level (Optional[str]) – Specifies the type of logs that DataSync publishes to a Amazon CloudWatch Logs log group. To specify the log group, see CloudWatchLogGroupArn . If you set LogLevel to OFF , no logs are published. BASIC publishes logs on errors for individual files transferred. TRANSFER publishes logs for every file or object that is transferred and integrity checked.
mtime (Optional[str]) – A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase. This option is required for cases when you need to run the same task more than one time. Default value: PRESERVE PRESERVE : Preserve original Mtime (recommended) NONE : Ignore Mtime . .. epigraph:: 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 .
object_tags (Optional[str]) – Specifies whether object tags are preserved when transferring between object storage systems. If you want your DataSync task to ignore object tags, specify the NONE value. Default Value: PRESERVE
overwrite_mode (Optional[str]) – Specifies whether data at the destination location should be overwritten or preserved. If set to NEVER , a destination file for example will not be replaced by a source file (even if the destination file differs from the source file). If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes. Some storage classes have specific behaviors that can affect your Amazon S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync .
posix_permissions (Optional[str]) – 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. This option should be set only for Network File System (NFS), Amazon EFS, and Amazon S3 locations. For more information about what metadata is copied by DataSync, see Metadata Copied by DataSync . Default value: PRESERVE PRESERVE : Preserve POSIX-style permissions (recommended). NONE : Ignore permissions. .. epigraph:: AWS DataSync can preserve extant permissions of a source location.
preserve_deleted_files (Optional[str]) –
A value that specifies whether files in the destination that don’t exist in the source file system are preserved. This option can affect your storage costs. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the AWS DataSync User Guide . Default value: PRESERVE PRESERVE : Ignore destination files that aren’t present in the source (recommended). REMOVE : Delete destination files that aren’t present in the source.
preserve_devices (Optional[str]) – A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and re-create the files with that device name and metadata on the destination. DataSync does not copy the contents of such devices, only the name and metadata. .. epigraph:: 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.
security_descriptor_copy_flags (Optional[str]) – A value that determines which components of the SMB security descriptor are copied from source to destination objects. This value is only used for transfers between SMB and Amazon FSx for Windows File Server locations, or between two Amazon FSx for Windows File Server locations. For more information about how DataSync handles metadata, see How DataSync Handles Metadata and Special Files . Default value: OWNER_DACL OWNER_DACL : For each copied object, DataSync copies the following metadata: - Object owner. - NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object. When you use option, DataSync does NOT copy the NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object. OWNER_DACL_SACL : For each copied object, DataSync copies the following metadata: - Object owner. - NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object. - NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object. Copying SACLs requires granting additional permissions to the Windows user that DataSync uses to access your SMB location. For information about choosing a user that ensures sufficient permissions to files, folders, and metadata, see user . NONE : None of the SMB security descriptor components are copied. Destination objects are owned by the user that was provided for accessing the destination location. DACLs and SACLs are set based on the destination server’s configuration.
task_queueing (Optional[str]) – Specifies whether your transfer tasks should be put into a queue during certain scenarios when running multiple tasks . This is ENABLED by default.
transfer_mode (Optional[str]) – A value that determines whether DataSync transfers only the data and metadata that differ between the source and the destination location, or whether DataSync transfers all the content from the source, without comparing it to the destination location. CHANGED : DataSync copies only data or metadata that is new or different from the source location to the destination location. ALL : DataSync copies all source location content to the destination, without comparing it to existing content on the destination.
uid (Optional[str]) – The user ID (UID) of the file’s owner. Default value: INT_VALUE INT_VALUE : Preserve the integer value of the UID and group ID (GID) (recommended). NAME : Currently not supported NONE : Ignore the UID and GID.
verify_mode (Optional[str]) – A value that determines whether a data integrity verification is performed at the end of a task execution after all data and metadata have been transferred. For more information, see Configure task settings . Default value: POINT_IN_TIME_CONSISTENT ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred. POINT_IN_TIME_CONSISTENT : Scan the entire source and entire destination at the end of the transfer to verify that the source and destination are fully synchronized. This option isn’t supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes. NONE : No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

PRESERVE : Preserve POSIX-style permissions (recommended).

NONE : Ignore permissions. .. epigraph:

AWS DataSync can preserve extant permissions of a source location.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-datasync-task-options.html#cfn-datasync-task-options-posixpermissions

preserve_deleted_files

A value that specifies whether files in the destination that don’t exist in the source file system are preserved.

This option can affect your storage costs. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync in the AWS DataSync User Guide .

Default value: PRESERVE

PRESERVE : Ignore destination files that aren’t present in the source (recommended).

REMOVE : Delete destination files that aren’t present in the source.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-datasync-task-options.html#cfn-datasync-task-options-preservedeletedfiles

preserve_devices

A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and re-create the files with that device name and metadata on the destination.

DataSync does not copy the contents of such devices, only the name and metadata. .. epigraph:

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.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-datasync-task-options.html#cfn-datasync-task-options-preservedevices

security_descriptor_copy_flags

A value that determines which components of the SMB security descriptor are copied from source to destination objects.

This value is only used for transfers between SMB and Amazon FSx for Windows File Server locations, or between two Amazon FSx for Windows File Server locations. For more information about how DataSync handles metadata, see How DataSync Handles Metadata and Special Files .

Default value: OWNER_DACL

OWNER_DACL : For each copied object, DataSync copies the following metadata:

Object owner.
NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.

When you use option, DataSync does NOT copy the NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

OWNER_DACL_SACL : For each copied object, DataSync copies the following metadata:

Object owner.
NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.
NTFS system access control lists (SACLs), which are used by administrators to log attempts to access a secured object.

Copying SACLs requires granting additional permissions to the Windows user that DataSync uses to access your SMB location. For information about choosing a user that ensures sufficient permissions to files, folders, and metadata, see user .

NONE : None of the SMB security descriptor components are copied. Destination objects are owned by the user that was provided for accessing the destination location. DACLs and SACLs are set based on the destination server’s configuration.

task_queueing

Specifies whether your transfer tasks should be put into a queue during certain scenarios when running multiple tasks . This is ENABLED by default.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-datasync-task-options.html#cfn-datasync-task-options-taskqueueing

transfer_mode

A value that determines whether DataSync transfers only the data and metadata that differ between the source and the destination location, or whether DataSync transfers all the content from the source, without comparing it to the destination location.

CHANGED : DataSync copies only data or metadata that is new or different from the source location to the destination location.

ALL : DataSync copies all source location content to the destination, without comparing it to existing content on the destination.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-datasync-task-options.html#cfn-datasync-task-options-transfermode

uid

The user ID (UID) of the file’s owner.

Default value: INT_VALUE

INT_VALUE : Preserve the integer value of the UID and group ID (GID) (recommended).

NAME : Currently not supported

NONE : Ignore the UID and GID.

Link:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-datasync-task-options.html#cfn-datasync-task-options-uid

verify_mode

A value that determines whether a data integrity verification is performed at the end of a task execution after all data and metadata have been transferred.

For more information, see Configure task settings .

Default value: POINT_IN_TIME_CONSISTENT

ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.

POINT_IN_TIME_CONSISTENT : Scan the entire source and entire destination at the end of the transfer to verify that the source and destination are fully synchronized. This option isn’t supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.

NONE : No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.

TaskScheduleProperty

class CfnTask.TaskScheduleProperty(*, schedule_expression)

Bases: object

Specifies the schedule you want your task to use for repeated executions.

For more information, see Schedule Expressions for Rules .

Parameters:: schedule_expression (str) – A cron expression that specifies when AWS DataSync initiates a scheduled transfer from a source to a destination location.
