implements SdkPojo, Serializable, ToCopyableBuilder<Options.Builder,​Options>

    Indicates how your transfer task is configured. These options include how DataSync handles files, objects, and their associated metadata during your transfer. You also can specify how to verify data integrity, set bandwidth limits for your task, among other options.

    Each option has a default value. Unless you need to, you don't have to configure any option before calling StartTaskExecution.

    You also can override your task options for each task execution. For example, you might want to adjust the LogLevel for an individual execution.

      • verifyMode

        public final VerifyMode verifyMode()

        Specifies how and when DataSync checks the integrity of your data during a transfer.

        • ONLY_FILES_TRANSFERRED (recommended) - DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination.

          We recommend this option when transferring to S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive storage classes. For more information, see Storage class considerations with Amazon S3 locations.

        • POINT_IN_TIME_CONSISTENT (default) - At the end of the transfer, DataSync scans the entire source and destination to verify that both locations are fully synchronized.

          If you use a manifest, DataSync only scans and verifies what's listed in the manifest.

          You can't use this option when transferring to S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive storage classes. For more information, see Storage class considerations with Amazon S3 locations.

        • NONE - DataSync doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer.

        If the service returns an enum value that is not available in the current SDK version, verifyMode will return VerifyMode.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from verifyModeAsString().

        Returns:

        Limits the bandwidth used by a DataSync task. For example, if you want DataSync to use a maximum of 1 MB, set this value to 1048576 (=1024*1024).

        Returns:

      • transferMode

        public final TransferMode transferMode()

        Determines whether DataSync transfers only the data and metadata that differ between the source and the destination location or transfers all the content from the source (without comparing what's in the destination).

        • CHANGED (default) - DataSync copies only data or metadata that is new or different content from the source location to the destination location.

        • ALL - DataSync copies everything in the source to the destination without comparing differences between the locations.

        If the service returns an enum value that is not available in the current SDK version, transferMode will return TransferMode.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from transferModeAsString().

      • securityDescriptorCopyFlags

        public final SmbSecurityDescriptorCopyFlags securityDescriptorCopyFlags()

        Specifies 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 FSx for Windows File Server locations. For more information, see how DataSync handles metadata.

        • OWNER_DACL (default) - For each copied object, DataSync copies the following metadata:

          • The object owner.

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

            DataSync won't copy NTFS system access control lists (SACLs) with this option.

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

          • The object owner.

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

          • 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 with the right permissions, see required permissions for SMB, FSx for Windows File Server, or FSx for ONTAP (depending on the type of location in your transfer).

        • 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.

        If the service returns an enum value that is not available in the current SDK version, securityDescriptorCopyFlags will return SmbSecurityDescriptorCopyFlags.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from securityDescriptorCopyFlagsAsString().
