describeBackups method

Future<DescribeBackupsResponse> describeBackups({
  1. List<String>? backupIds,
  2. List<Filter>? filters,
  3. int? maxResults,
  4. String? nextToken,
})

Returns the description of specific Amazon FSx backups, if a BackupIds value is provided for that backup. Otherwise, it returns all backups owned by your AWS account in the AWS Region of the endpoint that you're calling.

When retrieving all backups, you can optionally specify the MaxResults parameter to limit the number of backups in a response. If more backups remain, Amazon FSx returns a NextToken value in the response. In this case, send a later request with the NextToken request parameter set to the value of NextToken from the last response.

This action is used in an iterative process to retrieve a list of your backups. DescribeBackups is called first without a NextTokenvalue. Then the action continues to be called with the NextToken parameter set to the value of the last NextToken value until a response has no NextToken.

When using this action, keep the following in mind:

  • The implementation might return fewer than MaxResults file system descriptions while still including a NextToken value.
  • The order of backups returned in the response of one DescribeBackups call and the order of backups returned across the responses of a multi-call iteration is unspecified.

May throw BadRequest. May throw FileSystemNotFound. May throw BackupNotFound. May throw InternalServerError.

Parameter backupIds : IDs of the backups you want to retrieve (String). This overrides any filters. If any IDs are not found, BackupNotFound will be thrown.

Parameter filters : Filters structure. Supported names are file-system-id and backup-type.

Parameter maxResults : Maximum number of backups to return in the response (integer). This parameter value must be greater than 0. The number of items that Amazon FSx returns is the minimum of the MaxResults parameter specified in the request and the service's internal maximum number of items per page.

Parameter nextToken : Opaque pagination token returned from a previous DescribeBackups operation (String). If a token present, the action continues the list from where the returning call left off.
