Backup gateway connects Backup to your hypervisor, so you can create, store, and restore backups of your virtual machines (VMs) anywhere, whether on-premises or in the VMware Cloud (VMC) on Amazon Web Services.
Add on-premises resources by connecting to a hypervisor through a gateway. Backup will automatically discover the resources in your hypervisor.
Use Backup to assign virtual or on-premises resources to a backup plan, or run on-demand backups. Once you have backed up your resources, you can view them and restore them like any resource supported by Backup.
To download the Amazon Web Services software to get started, navigate to the Backup console, choose Gateways, then choose Create gateway.
\n\n## Installing\n\nTo install this package, use the CLI of your favorite package manager:\n\n- `npm install @aws-sdk/client-backup-gateway`\n- `yarn add @aws-sdk/client-backup-gateway`\n- `pnpm add @aws-sdk/client-backup-gateway`\n\n## Getting Started\n\n### Import\n\nThe AWS SDK is modulized by clients and commands.\nTo send a request, you only need to import the `BackupGatewayClient` and\nthe commands you need, for example `ListGatewaysCommand`:\n\n```js\n// ES5 example\nconst { BackupGatewayClient, ListGatewaysCommand } = require(\"@aws-sdk/client-backup-gateway\");\n```\n\n```ts\n// ES6+ example\nimport { BackupGatewayClient, ListGatewaysCommand } from \"@aws-sdk/client-backup-gateway\";\n```\n\n### Usage\n\nTo send a request:\n\n- Instantiate a client with configuration (e.g. credentials, region).\n - See [docs/CLIENTS](https://github.com/aws/aws-sdk-js-v3/blob/main/supplemental-docs/CLIENTS.md) for configuration details.\n - See [@aws-sdk/config](https://github.com/aws/aws-sdk-js-v3/blob/main/packages/config/README.md) for additional options.\n- Instantiate a command with input parameters.\n- Call the `send` operation on the client, providing the command object as input.\n\n```js\nconst client = new BackupGatewayClient({ region: \"REGION\" });\n\nconst params = { /** input parameters */ };\nconst command = new ListGatewaysCommand(params);\n```\n\n#### Supported Message Protocols\n\nThis client supports multiple protocols.\n\nThe default for this client is **AWS JSON (RPC) 1.0**.\n\nWe have selected this default based on our evaluation of the\nperformance characteristics of this protocol format in JavaScript. You don't need to change it,\nbut you have the option to do so, for example to support existing integrations or tests.\nSelecting a non-default protocol changes the format\nof the data sent over the network, but does not affect how you interact with the\nclient using JavaScript objects.\n\nInstall the `@aws-sdk/config` package to access alternate protocols.\n\nSee [AWS Protocols](https://smithy.io/2.0/aws/protocols/index.html) for more information.\n\n##### AWS JSON (RPC) 1.0\n\nThis protocol uses JSON payloads.\n```js\nimport { AwsJson1_0Protocol } from \"@aws-sdk/config/protocol\";\n\nconst client = new BackupGatewayClient({\n protocol: AwsJson1_0Protocol\n});\n```\n\n##### Smithy RPC v2 CBOR\n\nThis protocol uses CBOR payloads.\n```js\nimport { AwsSmithyRpcV2CborProtocol } from \"@aws-sdk/config/protocol\";\n\nconst client = new BackupGatewayClient({\n protocol: AwsSmithyRpcV2CborProtocol\n});\n```\n\n#### Async/await\n\nWe recommend using the [await](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await)\noperator to wait for the promise returned by send operation as follows:\n\n```js\n// async/await.\ntry {\n const data = await client.send(command);\n // process data.\n} catch (error) {\n // error handling.\n} finally {\n // finally.\n}\n```\n\n#### Promises\n\nYou can also use [Promise chaining](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises#chaining).\n\n```js\nclient\n .send(command)\n .then((data) => {\n // process data.\n })\n .catch((error) => {\n // error handling.\n })\n .finally(() => {\n // finally.\n });\n```\n\n#### Aggregated client\n\nThe aggregated client class is exported from the same package, but without the \"Client\" suffix.\n\n`BackupGateway` extends `BackupGatewayClient` and additionally supports all operations, waiters, and paginators as methods.\nThis style may be familiar to you from the AWS SDK for JavaScript v2.\n\nIf you are bundling the AWS SDK, we recommend using only the bare-bones client (`BackupGatewayClient`).\nMore details are in the blog post on\n[modular packages in AWS SDK for JavaScript](https://aws.amazon.com/blogs/developer/modular-packages-in-aws-sdk-for-javascript/).\n\n```ts\nimport { BackupGateway } from \"@aws-sdk/client-backup-gateway\";\n\nconst client = new BackupGateway({ region: \"REGION\" });\n\n// async/await.\ntry {\n const data = await client.listGateways(params);\n // process data.\n} catch (error) {\n // error handling.\n}\n\n// Promises.\nclient\n .listGateways(params)\n .then((data) => {\n // process data.\n })\n .catch((error) => {\n // error handling.\n });\n\n// callbacks (not recommended).\nclient.listGateways(params, (err, data) => {\n // process err and data.\n});\n```\n\n### Troubleshooting\n\nWhen the service returns an exception, the error will include the exception information,\nas well as response metadata (e.g. request id).\n\n```js\ntry {\n const data = await client.send(command);\n // process data.\n} catch (error) {\n const { requestId, cfId, extendedRequestId } = error.$metadata;\n console.log({ requestId, cfId, extendedRequestId });\n /**\n * The keys within exceptions are also parsed.\n * You can access them by specifying exception names:\n * if (error.name === 'SomeServiceException') {\n * const value = error.specialKeyInException;\n * }\n */\n}\n```\n\nSee also [docs/ERROR_HANDLING](https://github.com/aws/aws-sdk-js-v3/blob/main/supplemental-docs/ERROR_HANDLING.md).\n\n## Getting Help\n\nPlease use these community resources for getting help.\nWe use GitHub issues for tracking bugs and feature requests, but have limited bandwidth to address them.\n\n- Visit the [Developer Guide](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/welcome.html)\n or [API Reference](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/index.html).\n- Check out the blog posts tagged with [`aws-sdk-js`](https://aws.amazon.com/blogs/developer/tag/aws-sdk-js/)\n on AWS Developer Blog.\n- Ask a question on [StackOverflow](https://stackoverflow.com/questions/tagged/aws-sdk-js) and tag it with `aws-sdk-js`.\n- Join the AWS JavaScript community on [gitter](https://gitter.im/aws/aws-sdk-js-v3).\n- If it turns out that you may have found a bug, please [open an issue](https://github.com/aws/aws-sdk-js-v3/issues/new/choose).\n\nTo test your universal JavaScript code in Node.js, browser and react-native environments,\nvisit our [code samples repo](https://github.com/aws-samples/aws-sdk-js-tests).\n\n## Contributing\n\nThis client code is generated automatically.
